4. Servicing: Do not attempt to service the Principal  
Grand subwoofer beyond that described in the  
operating instructions. All other services should be  
referred to qualified service personnel.  
5. Indoor use: Principal Grand is designed for indoor  
use only in a dry, domestic environment and for  
use within a temperature range of 10° 40°C (50°  
105°F).  
6. Objects and liquid damage: Do not let objects or  
liquids fall into the Principal Grand. Do not place a  
container with liquid on top of this product.  
7. Water and moisture: Do not operate the  
Principal Grand near water, for example near a  
bath-tub, or in a wet basement nor near a swim-  
ming pool.  
8. Wall or ceiling mounting: Principal Grand is  
neither suitable for mounting into the wall nor for  
mounting on the ceiling. If you choose a position  
on the wall or on a shelf, it will be necessary that  
the subwoofer be properly secured into position.  
Otherwise the subwoofer could fall due to the  
exceptional vibrations that can cause the unit to  
move or “walk.”  
9. Ventilation: Be sure to position the subwoofer so  
that its location or position does not interfere with  
its proper ventilation. The rear of the Principal  
Grand contains a metal panel that acts as a heat  
sink for the amplifier. It is particularly important  
that this area be clear to allow for proper air flow.

For this reason it is not recommended to build the  
Principal Grand into any cabinetry that does not  
contain special cooling capabilities.  
10.Heat: Position the Principal Grand away from heat  
sources such as radiators, heaters, stoves or other  
appliances (including amplifiers) that produce  
heat.  
11.Power sources: Connect this subwoofer to an  
appropriate AC power outlet only of the voltage  
type marked on the Principal Grand (this will vary  
depending on the voltage in the country you  
purchased the unit in).  
12.Power cord protection: Route the power cord so  
that it is not likely to be walked on or pinched by  
items placed on or near it paying particular atten-  
tion to the plug end, power socket and the input of  
the subwoofer itself.  
13.Lightning storms: Unplug the Principal Grand as  
well as the rest of your entire audio video system  
during electrical storms.  
14.Cleaning: This product should only be cleaned in  
accordance with this manual.

1 Power Cord Input  
2 Fuse Socket (use only the supplied fuse or one  
that is the same type and rating only!)  
3 Master Power Switch  
4 High-Level Inputs: This input derives the signal  
directly from the amplifiers output. This should be  
used when the Phono (RCA) Plug inputs are not  
available.  
5 Phono (RCA) Plug Inputs: This is the most  
common connection input that derives the signal  
either from the pre-amplifiers output or the subwoofer  
output of an audio video pro-cessor/receiver.  
Attention: If only one Phono (RCA) Plug connection  
is used for the subwoofer output of an audio/video  
processor/ receiver, it does not matter which, either  
left or right, input you use. If you have a need for  
additional gain, it may be necessary to use a Y-  
Adapter to use both Left and Right labeled inputs.  
6 Adjustable Crossover (Frequency) Control: The  
crossover point is determined by listening. Where this  
ultimately sets up best is determined by the in-room  
performance of your main loudspeakers unless the  
Principal Grand is being used exclusively for LFE. In  
such an application the crossover should be set to the  
highest point, thus relying exclusively on the base  
control  
available  
through  
your  
audio  
video  
processor/receiver.

7 Volume Control: This adjusts the overall volume  
level of the Principal Grand relative to the main  
loudspeakers regard-less of whether the High-Level or  
the Line-Level inputs are used.  
8 Phase Switch: This critical switch allows for the  
timing of the subwoofer to be in phase (in time) with  
the main loudspeakers. The correct location is the  
position that produces the greatest output when  
combined with the loudspeakers. After finding this  
stronger or louder position, it may be necessary to  
lower the overall volume of the Principal Grand.  
9 On/Auto Switch: The On-Position places the  
Principal Grand in an always On- position while the  
Auto-Position automati-cally places the Principal Grand  
into standby when there is no signal for 15 minutes.  
While in the Auto-Position the Principal Grand with  
return to On once signal is detected.  
Accessories  
Power cord 1 piece  
Fuse 1 piece (1 fuse already installed)

Setup procedure for the Principal Grand  
subwoofer  
1. In order to prevent scratches and finger-prints we  
have supplied with each Principal Grand a pair of our  
special cloth gloves. We highly recommend using  
these throughout the entire setup process.  
2. Connect the Principal Grand subwoofer using either  
a pair of speaker connections, a pair of Phono (RCA)  
cables for stereo or a single LFE cable subwoofer  
cable. In each case we recommend that you discuss  
the best connection scheme with your retailer and  
purchase the appropriate cable choice.  
3. Connect the Principal Grand to the AC power  
outlet.  
4. Turn on the Master Power Switch.  
Note: If the power LED does not immediately  
illuminate, please check that the On/Auto switch is in  
the Auto position. If this is the case, it will be  
necessary for the subwoofer to receive and audio  
signal before the LED will illuminate. For the setup  
procedure you may want to place this switch in the  
On-Position and then return it to the Auto-Position for  
normal operation.  
5. For the ideal final setup as well as the most  
efficient use of setup time, please follow these simple  
dial-in instructions.

6. After the Principal Grand subwoofer is fully broken  
in, it may be necessary for you to make some final,  
minor adjustments to the crossover and overall gain  
settings.  
Start with the controls in the following positions:  
i.  
Crossover Control: middle position  
Volume: start in the middle position  
Phase: 0°  
ii.  
iii.  
6. Listen: It is important that you listen to music  
while making the final proper adjustments to the  
Principal Grand. Start with a piece of music that has  
an abun-dance of consistent and rhythmic low bass. A  
recording with  
a
plucked double-bass properly  
recorded should work quite well for this process.  
a. Volume: Make necessary adjustments so that the  
volume of the subwoofer is similar to that of the main  
loudspeakers. It is possible that you will have to turn  
the Principal Grand´s gain control to near maximum.  
The choice of operating range of this special gain  
control we have used was determined by obtaining the  
best possible sound quality.  
b. Phase: While listening to music, switch the Phase-  
Control between 0° and 180°. Select the position that  
offers the greatest overall bass output this is the  
position that the Principal Grand subwoofer is working  
in time or in-phase with your main loudspeakers.

c. Crossover: After adjusting the Phase-Control, it will  
be necessary to determine the best crossover range  
for your in-room performance. Turn this control to the  
lowest setting available. It may be necessary to again  
adjust the overall volume. Most frequently at this point  
it will be necessary to raise the volume a position or  
two. Then adjust or raise the crossover setting until  
the overall bass performance begins to become  
overwhelming or “boomy.” When this happens, lower  
the crossover setting until the “boominess” goes away.  
e. Fine Adjustments: At this point you may find that a  
position or two higher on crossover will sound better  
with the overall volume a position or two lower. This  
will produce a slightly “warmer” bass contour while the  
opposite of having the volume a bit higher but a  
crossover setting that is slightly lower will produce a  
“faster” and more powerful lower bass output. This  
final fine adjustment process is of personal preference  
and thus listening to a couple different pieces of music  
should be used for this step.  
Note: It is usually better to use a lower crossover  
setting with slightly higher overall volume settings in  
order obtain the optimum in room bass extension.  
Since all speakers have different performance in all  
rooms and with different associated other equipment,  
it is impossible to determine what the final setting for  
the crossover, gain or even phase will ultimately be.  
The only way to properly setup this device, or any  
other piece of a fine audio or audio/video equipment,  
is by listening.  
Thank you and Happy Listening!
