Quick Start - Continued
• Now, power up the sub88.
• Press and hold the rear panel SYETEM LEVEL DOWN
control for 5 seconds. This will let you start with the
monitor system turned all the way off.
Now, power up your active satellite speakers at set
the volume for the normal operating level.
• Apply a signal (like music from a CD or MP3 player)
and check the mixer master level meter to see that
you have a good signal.
Once you confirm a good signal is being sent from the
mixer, use the sub88's rear panel SYSTEM LEVEL UP and
DOWN controls to set the monitor system to the desired
operating volume. Bure sure to check the front panel VU
meter to avoid cliping the sub88's input.
Resolv sub88 Control Panel
The sub88’s control panel provides the connections and
user interface to the sub88’s internal electronic cross-
over and power amplifier section. The internal ampli-
fier is a 80 Watt power amplifier capable of producing
incredible bass output. The sub88 employs an elec-
tronic 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 tremen-
dous benefit in sound quality by running your satellites
speakers from the sub88’s High-Pass outputs. The rea-
son for this is that when your satellite speaker receives
the filtered output from the sub88, 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 sub88’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 satel-
lites to reproduce, resulting in a much cleaner sound
with more headroom.

Operating the Resolv sub88
Note: You can fine tune your system response to your par-
ticular liking by adjusting the crossover FREQUENCY control,
as well as, the balance between the sub and satellite levels. If
you do not have a digital real time analyzer, you’ll have to use
your ears by checking the sound of various recordings that are
familiar to you. You can also use a digital RTA like the Samson
D1500 to flatten the system perfectly.
