ti1600.5 - Operational Details
FRONT/REAR/ SUB INPUT
Connect signal cables from the head unit to these terminals.
LEVEL
Used to reach maximum amplifier power with a wide variety of headunits.
2ch/4ch/5ch INPUT SELECTOR
FRONT AND REAR SPEAKER OUTPUTS
2ch: Headunit has one pair of cables into front Input.
4ch: Headunit has two pairs of cables into front and rear inputs.
5ch: Headunit has three pairs of cables into front, rear and sub inputs.
Used to connect the amplifier to speakers. Minimum impedance is 2 ohm stereo/4 ohm
bridged. Use left channel + and right channel - for bridged mode.
SUB CHANNEL SPEAKER OUTPUTS
Used to connect the amplifier to subwoofers. Minimum impedance is 1 ohm.
HP/LP CROSSOVER FREQUENCY
Controls the crossover point for the speaker outputs.
CONFIG
FLAT/OFF: Crossovers are turned off
HP: High pass crossover is on
LP/BP: Low and High Pass crossovers are both on, creating a Bandpass (BP)
setting for midbass drivers.
Notes: The front HP and rear LP crossovers extend to 4kHz, so its possible
to run a component speaker system fully active. The tweeters would be
powered by the front channels and the midbasses by the rear channels. Be
sure to check with your speaker’s manufacture for the correct tweeter and
midbass crossover points to avoid speaker damage.
Subwoofer channel LP crossover and subsonic filter are always on.
Amplifier Owner’s Manual
BASS BOOST
LOW PASS LEVEL CONTROL (LPL)
Variable bass boost from 0 to +18dB @ 45 Hz.
This port is for connecting the optional remote level control (LPL44). This allows up
to 20dB of volume adjustment. This is not a bass boost, it controls the level of the
sub channel.
SUBSONIC CROSSOVER FREQUENCY
Controls the highpass crossover point for the speaker outputs to
eliminate extreme low frequencies.
REMOTE MONITORING DISPLAY (RMD)
Connect optional RMD Voltage Display to this port.
12V+
This must be connected to the fused positive terminal (+12V) of the car’s
battery. The fuse must be located within 18 inches of the battery. 1/0
gauge wire REQUIRED.
PEAK INDICATOR
Lights when the amplifier reaches near maximum output. Under normal
operation the peak indicator should be flashing during the peaks of the
music. Peak indicator should not stay lit for long periods of time (more
than 2 or 3 seconds), if this is the case you need to reduce system volume
or level of the amplifier.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming
from the head unit or ignition.
PROTECT INDICATOR
Lights red if there is a problem with the audio system, see the troubleshooting page.
GND
This must be connected to the negative terminal of the car’s battery or
bolted to a clean, unpainted part of the chassis of the vehicle. 1/0 gauge
wire REQUIRED.
Amplifier Owner’s Manual
System tuning
1. Install all system fuses.
Note: For subwoofers controlled by the Remote level
2. Set the amplifier’s input sensitivity controls to their
minimum positions (full counterclockwise).
control, keep the level setting from step 11 or 12. Use the
control to blend subwoofers with the rest of the system.
The correct subwoofer volume will change depending on
road noise and differences in recordings.
3. Set all amplifier crossover switches according to your
system’s design.
15. Fine tune crossover frequencies to achieve the smoothest
possible blending of each speaker set.
4. Make preliminary adjustments to the crossover frequency,
usually 80Hz is good starting point for high and low pass. It
may be necessary to fine tune the crossover frequency later 16. Adjust the Bass Equalization/Boost Controls on the
for the best overall sound quality.
amplifier, headunit or processor upstream if necessary to
increase output.
5. If using a Remote Subwoofer Level Control, set it to
maximum (full clockwise).
Note: Use these controls sparingly. Every 3dB of boost
requires double the power at 45Hz. If your subwoofer
system requires a lot of boost to sound good, there may
be a problem. Look for out-of-phase woofers, a leaking
subwoofer box, or incorrect box size.
6. Turn the headunit on with the volume set to minimum.
7. Visually check the amplifier’s has powered on by the power
LED.
17. With all levels set correctly, the system will reach overall
maximum undistorted output at the volume level set in
step 10.
8. Check the condition of all other components to make sure
they are powered up.
9. Set the headunit’s tone controls, balance, and fader to the
center (flat) position. Turn off any loudness or other signal
processing features.
10. Set the volume control of the headunit for maximum
undistorted output (on most headunits this will be
approximately 7/8 of maximum volume). Use a very clear,
dynamic recording and begin to listen.
11. Turn up the sensitivity or input level control on the
amplifier until the speakers reach maximum undistorted
output.
12. Repeat sensitivity level adjustments one at time for each
set of channels.
13. Reduce the headunit’s volume to a comfortable level.
14. Listen to various musical selections to check the overall
system balance. Compare front to rear, midbass to
midrange, etc. If one speaker set is too loud compared to
another, then its level must be lowered to blend correctly
with the other speakers.

TROUBLESHOOTING
NO POWER:
NO SOUND FROM ONE SIDE:
Check voltage at amplifier with a DMM (volt meter), +12v
Check the balance control in the head unit. Check speaker
connections. Check signal input connection.
and R (with head unit on) the voltage should register
between 12.2V and 14.6V when using the ground lead of
the amplifier. Check fuse at amplifier and at the battery. Use
a meter to verify connection from one end of the fuse to the
other, breaks may not always be visible. If the fuse is blown,
check the power wire and also the amplifier for a short. If
the short is in the amplifier itself, see your Phoenix Gold
dealer. If no short is present, replace the fuse.
VERY LOW OUTPUT:
Check your head unit’s fader control or the amplifier’s input
sensitivity level. Make sure subsonic frequency control is not
set too high and LP frequency control is not set too low at
the same time.
FREQUENT AMPLIFIER SHUTDOWN:
POWER WITHOUT SOUND:
This indicates chronic amplifier thermal shutdown because
of operation at consistently high internal temperatures.
High operating temperature can be caused by inadequate
ventilation. Make sure you are not running a lower than
recommend impedance. Also check for damaged speakers
or passive crossover systems. Finally, chronic thermal
shutdown may result from otherwise normal operation of
the amplifier at elevated output power levels, which can be
resolved by providing additional amplifier cooling, installing
Turn the amplifier off and check all input and output signal
cables and power connections. Check the speakers for
shorts with a DMM (volt meter) or by connecting them
to another audio source. After making sure everything is
correct, turn the amplifier on again.
POWER BUT PROTECT LED IS ON:
The red PROTECT LED lights when the amplifier shuts down
for either thermal or over-current protection. A high internal a higher-power amplifier, or reducing amplifier output level.
amplifier operating temperature will trigger thermal
shutdown: after it cools about 5°C, the amplifier will restart.
AMPLIFIER QUICKLY CYCLING ON AND OFF:
Check the amplifier’s connection to the battery. Check
battery voltage. If low, recharge or replace the battery.
Check all ground connections.
A shorted speaker lead or operation into unusually low
impedance loads will trigger over-current shutdown: cycle
power at the amplifier remote terminal to restore operation.
Check for shorted speaker wiring or damaged speakers or
crossover systems if over-current shutdown occurs.
