FRONT PANEL FEATURES

Input Jack – Designed to accept a

standard ¼ inch mono phone plug. For best
results, use a high -quality, shielded cable to
connect your instrument to the amplifier.

Gain Control – This regulates the first gain

stage of the preamplifier and controls the
amount of signal available to the system.

Set Level Indicator – Lights to indicate

that the preamp is sitting right on the sweet
spot of the gain balance and is at optimum
signal to noise as well as best overall head
room.

Compressor Indicator – Lights to

indicate that the signal has crossed the
threshold of the compression circuit and that
compression is taking place.

Compressor Bypass – Pulling the

enhance knob out will disengage the
compressor.

Enhance Control – Called the “Magic

Knob” by some, this complex control
simultaneously boosts the very low -bass,
upper middle, and high frequencies while
putting a dip in the lower middle frequencies.
It is flat when set to its minimum level.

Tone Control Section
Bass – This traditional shelving tone control

provides 15 db of boost or cut at 30 hz.

Quasi-Parametric Tone Control –

These three pairs of controls, with
overlapping frequencies, allow you to boost
or cut the tone at the desired frequency
center. The one octave fixed bandwidth
(Q=1) allows the controls to interac t
smoothly and musically.

Frequency control – Provided for low,

mid, and high frequency ranges, these
controls select the frequencies you wish to
boost or cut.

Boost/Cut Controls– Located beneath

each frequency selection control, these

controls will boos t or cut the selected
frequency by 15 db. They are flat at their
12:00 setting.

Treble – This is a traditional shelving-type

tone control. It provides 15 db of boost or
cut. The knee of the filter is at
approximately, 2KHz. The control is flat at
the 12:00 position.

EQ Clip Indicator – Flashes to indicate

clipping within the tone control circuit of the
preamplifier. This should never be lit up.

Master Level Control – Adjusts overall

system output.

Headphone Jack – Accepts standard ¼

stereo or mono he adphone plug.

Output Limit Indicators – Lights to

indicate activity of the power amplifier
limiting circuit, which protects the speaker
system from severe distortion. This LED
indicates that the amplifier has reached its
maximum output level.

On/Off Switch – This switch turns the

system power on or off. The switch
illuminates to indicate the presence of
current prior to the fuse.

REAR PANEL FEATURES

Combination Power Cord Jack and
Fuse Holder – The removable power cord

is attached here. Pulling the holder out of
the top of the power inlet accesses the fuse
carrier. Your unit was shipped with a spare
fuse inserted in the fuse carrier. USE ONLY

THE SAME SIZE AND TYPE FOR
REPLACMENT. U.S. users should make

sure the fuse holder is installed so the “115
VOLTS” reads right side up. For Europe the
230 should be right side up. Some European
models come with a holder marked (FUSE)
they are configured for 230 / 240 only and
must be adapted by a service tech for U.S.
standard voltage. The standard fuse for U.S.
use is (5) Amp slow blow or time delay.

Do not use fast blow fuses.

Amp Out – These two ¼ inch jacks accept

the speaker connection cables. The jacks
