Samson SUB88 Operating the Resolv sub88

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.
