Quick Start Guide  
* The PCA-2 does not include a phono preampli-  
fier stage. To connect a turntable, use a phono  
peamplifier.  
1. Place the PCA-2 in a rack or on a shelf in the  
audio/video system.  
2. Turn off all associated components  
3a. Connect the left and right analog audio out-  
puts from all audio/video source equipment to  
any of the inputs labeled 1-7 on the back of the  
PCA-2. Use input 1 for XLR type connections  
and inputs 2-7 for RCA type connections.  
For a complete list of input names see appendix  
A.  
3b. Connect the left and right analog audio out-  
puts from the back of the PCA-2 to the inputs of  
an audio amplifier. Use XLR type connectors if  
XLR inputs are available on the amplifier.  
There are 2 pair of both XLR and RCA outputs.  
There is no sonic difference between each pair  
of outputs.  
4. Plug the PCA-2 into the wall AC outlet. Use  
the supplied AC power cable, or an aftermarket  
power cable. For optimum results we recom-  
mend the use of a PS Audio xStream Power  
Cable.  
5. Once the PCA-2 is connected to power, the  
PCA-2 will initiate a countdown sequence from  
30 seconds. During this time the PCA-2 is initial-  
izing its internal circuitry.  
6. The PCA-2 will default to the 1st input (1 XLR)  
when it is ready for use.  
7. Use the Input Up/Down buttons to select the  
desired input and slowly raise the volume level  
using the front panel knob or the included IR  
remote control to a comfortable setting.  
Default Settings  
The PCA-2 comes from the factory with standard  
default settings that should work well for most  
situations. There are 25 custom setup param-  
eters which can be adjusted by the user as well  
as custom input names for all 7 inputs.

Note: Unplug the power cord before checking  
the fuse.  
Rear Panel Layout  
1. PS Bus and 12 Volt Triggers  
6. Analog Inputs  
The PCA-2 comes equipped with a built in PS  
Bus. The PS Bus allows other PS Audio prod-  
ucts equipped with a PS Bus to communicate via  
standard RJ11 phone cable.  
One analog XLR (balanced) and six analog RCA  
(single-ended) inputs allow for the connection of  
up to seven external sources.  
For a complete list of input names see Appendix  
A.  
Note: The phone cable must have at least  
four wires attached to the connector (a 2-line  
phone cable) to function properly.  
7. Expansion Slot Cover  
This cover is to be removed upon installing an  
expansion card for the PCA-2 (cards sold sepa-  
rately). See the instructions included with the  
expansion card for installation details.  
If communication between other non-PS prod-  
ucts is desired the 12 Volt Trigger can be used  
with other 12 Volt Trigger equipped products to  
relay commands such as power status. There  
are 2 output triggers and 1 input trigger (See  
“Using the 12 Volt Trigger” for more information).  
8. Loop Output  
The loop output is to be connected to the input  
of a device such as a tape deck or an equal-  
izer. The return loop signal should be connected  
to input number seven and can be activated by  
pressing the loop button.  
2. Ground Terminal  
The PCA-2 includes a grounding post for use  
with associated equipment, such as a turntable.  
Attach the grounding wire by tightening the bind-  
ing post to the wire.  
9. Analog Outputs  
Two pair of XLR and two pair of RCA analog out-  
puts are both active at all times to allow connec-  
tivity to any combination of amplifiers or to use  
the system in a bi-amped configuration. There  
is no sonic difference between each pair of out-  
puts.  
3. IEC Power Input  
15 amp male IEC standard power socket.  
4. Accessory Power Inputs  
Two Neutrik power connectors attach to the  
PCA-2 for use with the optional external power  
supply (sold separately).  
*The PCA-2 does not include a phono preampli-  
fier stage. To connect a turntable, use a phono  
peamplifier.  
5. Fuse  
The fuse is a 3 Amp fast blow. It can be removed  
by inserting a flat device into the fuse holder and  
twisting counter-clockwise.

Mute  
Front Panel Controls  
Pressing the Mute button will silence the output  
of the PCA-2. If Mute is activated, the number  
of the current input will still be displayed while  
the display will read MUTE. To exit the mute  
status, press mute again or simply adjust the vol-  
ume control.  
The PCA-2 front panel includes a volume knob  
and the following five buttons:

By default the PCA-2 will not produce any signal  
when in mute, however the mute volume level  
can be specified by the user (see Setup Menu).  
Mute  
Power On/Off  
Volume Knob  
The Power Button activates the front panel dis-  
play, engages the volume control and routes the  
input signal to the appropriate output(s). The PS  
logo will also illuminate blue.  
Adjusting the Volume Knob will increase or  
decrease the output volume. When the volume  
is adjusted it will numerically display the volume  
level in the display window. After 3 seconds the  
display will return to the input name. By default  
the volume level is displayed in a 0 to 100 scale.  
A decibel reference level scale from -90dB to  
+10dB can also be used (see Setup Menu).  
Pressing the Power Button again will put the  
PCA-2 in a standby mode. It will consume very  
little power and not pass any signal to the ampli-  
fier. The display and the logo will not illuminate.  
For optimum performance keep the PCA-2  
attached to a live outlet.  
Input Up/Down  
The Input Up/Down buttons cycle though  
all inputs. The front panel will display the  
number of the present input as well as  
the input name. This name can be  
specified by the user (see Setup  
Menu).  
Loop  
The Loop function will acti-  
vate the Loop output. Loop  
Output is a fixed level  
output, which is not  
affected by the vol-  
ume control. LOOP  
will illuminate in the  
front panel display  
when it is active.  
The Loop function  
is useful in conjunc-  
tion with recording  
devices or equaliza-  
tion equipment.

3. Volume  
Pressing the volume + or - buttons will increase  
or decrease the output volume. When the vol-  
ume is adjusted it will numerically display the vol-  
ume level in the display window. After 3 seconds  
it will return to display the input name. By default  
the volume level is displayed in a 0 to 100 scale.  
A decibel reference level scale from -90dB to  
+10dB can also be used (see also Setup Menu).  
4. Balance  
The Balance control is used to offset the relative  
volume level from one channel to the other. Use  
this control if your speakers, listening room or  
listening position are asymmetrical and must be  
corrected to overcome volume differences from  
proximity to the speakers or room resonances.  
The display will show an arrow which will point to  
the direction of the channel which is being offset.  
A number will illuminate showing the amount of  
offset in decibels.  
When the display reads [ <-- --> ] the system  
is centered and will send an equal level to each  
speaker.  
IR Remote Control  
5. Phase  
The Phase button will invert the polarity (some-

audio signal 180˚. Once pressed, PHASE will  
illuminate in the front panel display. Inverting the  
phase may be desired if there is a component  
in your system which inverts the absolute phase  
(polarity) and needs to be corrected. Pressing  
this button a second time will return the phase to  
the original non-inverting polarity.  
1. Power  
The Power button will toggle the PCA-2 from  
an active state to standby. While in standby no  
sound will pass through the PCA-2. The PCA-2  
will consume very little power in standby mode.  
6. HT (Home Theater Bypass)  
2. Mute  
Pressing the HT button will switch to the desig-  
nated Home Theater Bypass input. The desig-  
nated input can be specified in the setup mode.  
By default it is not assigned to any of the inputs,  
and pressing the HT button does not activate  
any function.  
Pressing the Mute button will silence the output  
of the PCA-2. If Mute is activated the number of  
the present input will still be displayed but the  
display will read MUTE. To exit the mute status,  
press mute again or adjust the volume control.  
By default the PCA-2 will not produce any signal  
when in mute, however the mute volume level  
can be specified by the user (see Setup Menu).  
In this mode the volume control will be bypassed  
and the audio signal will pass through the unit.  
The balance controls are also bypassed in this

There are 25 additional parameters that you can  
access in the Setup Menu. The Setup Menu is  
activated by pressing the Input Up and Input  
Down buttons simultaneously while powering on  
the PCA-2.  
CAUTION: Engaging the HT input without  
using a separate HT controller to control the  
volume may result in damage to your speak-  
ers.  
Pressing Input Up/Down will scroll through the  
25 setup parameters. The setup parameters are:

The default setting is either 100 (standard mode)  
or +10 (decibel mode).  
The default setting is STD.  
Volume On  
Headphone Operation  
The Volume ON setting can be adjusted to set  
a threshold for the volume level of the PCA-2  
when it is powered on. This is a useful protection  
feature to ensure that the PCA-2 is never set to  
too high a volume level for immediate playback,  
thus preventing damage to the connected speak-  
ers or amplifier.  
The Headphone operation setting allows the  
PCA-2 to either automatically mute the main out-  
puts or leave them active while the headphones  
are plugged in.  
Press the loop button to access the selec-  
tion screen. Rotate the volume knob to choose  
between ON or MUTE. If set to ON the PCA-2  
will continue to send audio to the main outputs  
if headphones are connected to the front panel  
jack. If set to MUTE the PCA-2 will mute the  
main outputs while headphones are connected  
to the front panel jack.  
Press the loop button to access the selection  
screen. Rotate the volume knob to select the  
Volume On threshold. The readout will display  
either a 0 to 100 scale or -90 to +10 dB scale,  
depending on what scale is chosen in Volume  
Display Mode.  
The default setting is MUTE.  
A good example of the Volume On threshold  
would be the following. Consider the V ON set-  
ting to be 60. If the last volume setting was only  
30, the PCA-2 will power on at 30 because it  
falls below the safe limits. However, if the last  
volume used was 80, the PCA-2 will automatical-  
ly activate the Volume On threshold and power  
on at a volume setting of 60, therefore prevent-  
ing damage to the connected speakers or ampli-  
fier.  
Network Address  
If more than one piece of PS Audio equipment  
is used in a system, then each piece connected  
to the PS Bus must have a unique Network  
Address. In this way, each piece of PS Audio  
equipment can easily be recognized and identi-  
fied in the Network Bus.  
Press the loop button to access the selection  
screen. There are 8 possible Addresses which  
can be selected by rotating the volume knob  
while in the Network Address mode.  
The default setting is either 100 (standard mode)  
or +10 (decibel mode). This indicates that the  
PCA-2 will power on with the last volume setting  
used and there is no threshold level in effect.  
If no Network Address is set then the PCA-2 will  
operate independently of any other PS Audio  
equipment on the PS Bus.  
Maximum Volume  
The Maximum Volume setting can be adjusted to  
limit the volume level of the PCA-2. This setting  
is useful if the PCA-2 is used in an environment  
where the volume could accidentally be bumped  
or turned to a volume that could potentially dam-  
age the connected speakers or amplifier.  
Network Group  
It is possible to assign the PCA-2 to a unique  
Network Group. Separate groups will allow all  
PS Audio products to exist on the same bus  
and still be able to communicate individually (by  
group).  
Press the loop button to access the selection  
screen. Rotate the volume knob to select the

directly with the PCA-2 while multi-channel  
sources can be selected by the HT controller  
while the PCA-2 is set to HT bypass mode.  
Reset  
If at any time it is necessary to reset all param-  
eters of the PCA-2 to their default settings, it can  
be done by pressing the Loop button twice while  
in RESET mode (See also the troubleshooting  
guide).  
CAUTION: Engaging the HT input without  
using a separate HT controller to control the  
volume may result in damage to your speak-  
ers.  
Using the Loop function  
Using the Home Theater Bypass  
The Loop function is used for sources with  
record monitoring or equalization functions,  
such as an external analog recording device or  
an external graphic or parametric equalizer. The  
loop function differs from a standard input as it  
will allow for monitoring of the source as the sig-  
nal passes through the associated equipment.  
The PCA-2 is designed to function as a stand-  
alone stereo preamp. However it can also inte-  
grate seamlessly into any home theater system  
and deliver uncompromised performance with  
2-channel sources.  
When using the Home Theater Bypass Function  
the PCA-2 will simply pass the audio signal from  
the specified input directly to all outputs. This will  
bypass the volume control and any balance set-  
tings.  
To use the Loop function, connect the associated  
equipment to Input 7. Then connect the Loop  
Out on the back of the PCA-2 to the input or  
"monitor in" on the associated equipment.  
The Home Theater Bypass Function is designed  
to work with a separate HT controller and mul-  
tichannel amplifier, however it will also function  
with some HT Receivers equipped with Pre-Outs  
and Main Inputs. The process for integrating the  
PCA-2 into a theater system is described below.  
To use the connected device in loop mode,  
select the desired input and then press the loop  
button on the remote or front panel. This will  
engage the loop operation and the signal will first  
pass through the connected equipment before  
the signal is sent through the volume control and  
output of the PCA-2.  
Connect the front left and front right Pre-outputs  
on the home theater controller to the desired  
input on the PCA-2. Either XLR or RCA type  
connectors can be used. The main output on the  
PCA-2 should then be connected to the front left  
and front right inputs on the multi-channel ampli-  
fier or the receiver Main Inputs. The remaining  
channels should connect directly to the amplifier  
from the HT controller.  
The Loop Input (Input 7) can also function as a  
normal audio input while the loop function is not  
activated.  
Using the 12 Volt Triggers  
The PCA-2 is equipped with three 12 Volt output  
triggers. Two triggers are for output and one is  
an input trigger.  
To designate the specific input as the HT Bypass  
simply select the input used for the bypass in the  
Setup Menu. (See Setup Menu for more informa-  
tion on selecting the HT Bypass input).  
The output triggers can be used to activate  
another audio/video product when the PCA-2 is  
powered on. Use a 3.5 mm mini jack cable to  
connect the device to the PCA-2.  
All 2-channel sources should be connected to  
the inputs on the PCA-2. Any multi-channel  
sources should be connected to the HT con-  
The input trigger will allow other devices to  
10

change the power status of the PCA-2 when con-  
nected. Use a 3.5 mm mini jack cable to connect  
the device to the PCA-2.  
Since control is bi-directional, one unit does not act  
as the “slave” or “master”. Instead each component  
has the capability to control the other.  
For more information on how to set the Network  
Group and Network Address for the PCA-2 see the  
Setup Menu section.  
While the PS Bus and the 12 Volt triggers can be  
used simultaneously they should not both be used  
with the same piece of equipment.  
For more information on how to set up the Network  
Group and Network Address for other PS Audio  
products please refer to the instruction manual sup-  
plied with the product.  
Using the PS Bus  
The PS Bus uses standard RJ11 (phone) cable to  
allow multiple pieces of PS Audio components to  
communicate with each other. The PS Bus offers  
more functionality than a standard 12 Volt trigger.  
The PS Bus can control other modes such as the  
display dim and power status to each amplifier  
channel.  
Note: The phone cable must have at least four  
wires attached to the connector (a 2-line phone  
cable) to function properly.  
To allow control between 2 or more PS audio prod-  
ucts set the Network Group to the same number  
for both products. Next set the Network Address to  
unique numbers so each product will have a  
discrete Network Address.  
*HCA-2 not included.

Trouble Shooting Guide  
The PCA-2 was designed to provide many years  
or reliable, trouble-free operation. In the event the  
PCA-2 is not working correctly, please refer to the  
following suggestions:

The PCA-2 allows the user to adjust the gain of  
setting from the last time it was used and ensure  
that this volume setting is safe for immediate play-  
each individual input. Follow these steps to check  
back. This information will be stored in memory  
this setting and make any necessary adjustments.  
even if the PCA-2 is powered down into standby.  
Turn the PCA-2 off. Press and hold both “Input”  
buttons and turn the PCA-2 back on. You are now  
in the Setup Menu.  
However, if the last volume setting was left above  
the Volume On threshold, the PCA-2 will acti-  
vate this protection system during the power up  
sequence.  
Scroll using the “Input Up/Down” buttons until you  
reach the appropriate input number and the word  
“GAIN” displayed after it, for example “3 GAIN.”  
Press the “Loop” button to enter this setting. Using  
the volume knob, adjust the gain setting to the  
desired level.  
To determine this threshold, the PCA-2 will refer  
to the setting called Volume On, or “V ON.” Follow  
these steps to check this setting and make any  
necessary adjustments.  
Turn the PCA-2 off. Press and hold both “Input”  
buttons and turn the PCA-2 back on. You are now  
in the Setup Menu.  
Exit the setup mode by pressing the power button.  
One channel (left or right) plays too loud or too  
quiet  
The balance control for the PCA-2 can be found  
on the remote control. Use these buttons to adjust  
the left and right channel levels to achieve the  
appropriate amount of balance.  
Scroll using the “Input Up/Down” buttons until you  
reach “V ON.” Press the “Loop” button to enter this  
setting and a number will be displayed. This level  
represents the Volume On threshold of the PCA-2  
after being powered on from standby. Using the  
volume knob, adjust the initial volume setting to  
the desired level.  
When the display reads [ <-- --> ] the system is  
centered and will send an equal level to each  
speaker.  
A low setting will ensure that the PCA-2 never  
powers up at a dangerous volume level.  
The volume is displaying negative numbers  
The PCA-2 is set to display the volume level in  
decibels, from -90 dB to +10 dB. This mode dis-  
plays the actual amount of attenuation. The PCA-2  
also allows the user to display the volume in a less  
technical format, from 0 to 100. Follow these steps  
to check this setting and make any necessary  
adjustments.  
Exit the setup mode by pressing the power button.

How do I reset the settings to factory default?  
The PCA-2 was designed to easily reset the  
microprocessor back to the original factory  
default. If the PCA-2 is displaying any characters  
in the front panel that seem abnormal, if the front  
panel buttons do not correlate with the display  
read-outs or to simply reset all settings back to  
the factory defaults follow these instructions.
