subwoofer amps use the most durable and accurate designs possible.
Get familiar with yours!
Volume/Gain Use “gain” (in conjunction with your Audio Video Receiver
(AVR) subwoofer output level control) to achieve bass level calibration to
your liking. Start your setup with the sub’s volume/gain no more than 1/4
to 1/3 of the way up (turned clockwise from the left).
Phase. Think of long bass waves as conflicting or enhancing each other,
depending on the timing of their arrival at your listening location (either
together, or not). Set phase to zero if your AVR offers settings for the
distance from your seat to your subwoofer. Adjust in small steps for
smooth sound with music playing if your AVR lacks a subwoofer distance
setting.
Line In/Out. Use the sub’s “Line In” jack (RCA) to connect the subwoofer
to the output jack of your AVR. A simple RCA signal cable is all you need
for either type configuration. .
Auto-On. Your Powered Box allows itself to be in an “Auto-On” mode…
or “On” all the time. With the former setting (the switch in the “Auto” posi-
tion) your subwoofer will “sense” that a DVD or CD etc. has begun and
switch its audio circuits on immediately (the “hard” power switch men-
tioned below must be set to “on”, naturally). A few minutes after a movie,
the Auto-On light will turn from Green to Red, switching portions of the
sub’s power supply back off.
Sometimes, with very low listening levels, your subwoofer might not get
enough of a bass signal from your AVR to “trip” the Auto-On circuit.
Should you ever find this to be the case you may leave this switch to “On”,
or turn up the AVR’s subwoofer level some (be sure to recalibrate chan-
nels levels with your sound meter afterwards).
Power. This heavy-duty two-position switch next to the power cord will
completely cut the power to your sub amp. Flip this switch to off before
you ever move the sub or change inputs or outputs. Do not plug this sub
into receiver convenience power outlets. Allow five minutes of “off” time
before switching back “on”.
Fuse. User replaceable, contact your dealer if you have trouble finding
one. The fuse can be accessed by a small door immediately next to the
power cord fitting (where you should also find a spare one for your use).
