Setting up the RESOLV 120a

CONFIGURING YOUR SPEAKER SYSTEM
Before you start plugging in cables, you should take a minute and decide how you want to interface your new
subwoofer. There are several ways you can interface the RESOLV 120a and two specific categories should be considered.
First, Stereo vs Mono operation, and second, whether High (powered) or Low (line) level inputs and outputs will be used.
Common Sub Operation
® ®
In most cases, a common sub ( mono) bass operation is
desired. This is true for several reasons, but mostly because
low frequencies produced by a subwoofer tend to be non-
directional. Since low frequency sound waves take so much
space to develop, you can't tell if the sub-bass is coming
from the left or right side,unless of course you're in a very
large room. Because of this phenomenon, just about all
sub-bass material is mixed in mono.
Stereo Sub Operation
Two RESOLV 120a's can be used in stereo in larger control
rooms for increased low end. In addition, two RESOLV
120a's can be used in stereo, even in smaller control rooms,
to help minimize standing waves. By using two subwoof-
®
®
ers at lower power, you can achieve a more even response
throughout the room.
Placing the RESOLV 120a
Because the low frequencies reproduced by the RESOLV
120a are non-directional, you can position the unit almost
anywhere. It is however, a good idea to keep the RESOLV
120a away from corners. Ideally the RESOLV 120a should
be positioned in the middle, and up close to, the wall you
are facing in the mixing position.

Operating the RESOLV 120a

RESOLV 120a Control Panel

The RESOLV 120a's control panel provides the connections and user interface to the RESOLV 120a's internal electronic
crossover and power amplifier section. The internal amplifier is a 120 Watt power amplifier capable of producing incred-
ible bass output. The RESOLV 120a employs an electronic crossover that adjusts the high frequency cutoff point for
the subwoofer, and also a high-pass output for your satellite speakers. You will achieve a tremendous benefit in sound
quality by running your satellites speakers from the RESOLV 120a's High-Pass outputs. The reason for this is that when
your satellite speaker receives the filtered output from the RESOLV 120a, it will no longer be looking at the frequencies
below the crossover point. Let's say your satellite speaker has a natural frequency roll-off at 70 Hz, and you are sending
full range signal (as low as 20Hz) to the satellite amplifier and speaker. Even though the speaker can only reproduce
70Hz and up, the amplifier is still outputting 20-70Hz, which is wasted power and ultimately turns into heat. By using the
RESOLV 120a's High-Pass output, the satellite amplifier and speaker never see the frequencies lower than what's set by
the Sweep frequency. This means you'll have more power dedicated to the frequencies you want the satellites to repro-
duce, resulting in a much cleaner sound with more headroom.
