1.) Mic Input - this is a 3 cond. XLR input jack for plugging in Lo-Z microphone or keyboard inputs. It has +15v Phantom
Power for condenser microphones.
2.) Line
Input #2 - this 1/4 2 conductor jack that allows you to plug in a Hi-z mic or keyboard or any line level source. It will
also accept guitar level signals as well.
3.) Line
Input #3 - this is a 1/4 2 conductor input jack that will also allow you to plug in a Hi-z mic or keyboard or any line level
source. It will also accept guitar level signals as well.
4.) Volume 1 - this is the level control for Input #1.
Slowly increase the control to increase the volume. If you are using a keyboard
with a preamp, set its level for a mid position before increasing this control, otherwise distortion may occur. Both inputs follow the same
tone circuit as the other input.
5.) Effects - this control determines how much signal from Input #1 goes to the effects buss. Clockwise sends more signal
to the buss.
6.) Volume 2 - this is the level control for Input #2. As above on Volume #1, the same applies.
7.) Effects On/Off - this switch determines whether the signal from Input #2 goes to the effects buss. The overall level on
the Effects Level control determines the effects level on that input.
8.) Volume 3 - this is the level control for Input #3. As above on Volume #1, the same applies.
9.) Effects On/Off - this switch determines whether the signal from Input #3 goes to the effects buss. The overall level on
the Effects Level control determines the effects level on that input.
10.) Low - this control is the bass control for the amplifier. It is active and is set to boost or cut frequencies at 100Hz. Turning
it fully clockwise, the signal is boosted +12db. Turning it counterclockwise, the low will be rolled off -12db.
11.) Lo-Mid - this control is the lower midrange control for the amplifier. It is active and set to boost or cut frequencies at
500Hz. Turning it fully clockwise, the signal is boosted +12db. Turning it counterclockwise, the low will be rolled off -12db.
12.) Hi-Mid - this control is the upper midrange control for the amplifier. It is active and set to boost or cut frequencies at
1.5KHz. Turning it fully clockwise, the signal is boosted +12db. Turning it counterclockwise, the low will be rolled off -12db.
13.) High - this control is the high frequency control for the amplifier. It is active and set to boost or cut frequencies at 5KHz.
Turning it fully clockwise, the signal is boosted +12db. Turning it counterclockwise, the low will be rolled off -12db.
14.) Master Volume - this is the Master Volume control for the entire amplifier.
15.) Effects On/Off - this switch engages the digital effects section.
16.) Effects Level - this control adds the digital effects section and mixes it into the main signal buss. Several different
effects are available.
17.) Program Select - this switch will select any of eight different effects. 4- Reverbs, 2- Echos, 1-Chorus and 1-Chorus/Reverb.
18.) Jewel Light - this jewel light lets you know that the amplifier is on.
19.) Power - this switch turns on and off the AC power to the amp.
Back Panel - (not pictured)
Speaker Out - this is a 2 conductor 1/4 speaker output jack. This will disconnect the internal speaker and allow an external
speaker cabinet to be employed. Rating is 8 ohms.
Line Output - this is a 2 conductor 1/4 line output jack. This will allow an external amplifier or mixing board to be supplied with
the signal from this amp.
Effects Loop I/O - these are 2-2 conductor 1/4 jacks. This will allow an external effects device or equalizer to be patched back in before
the power amp section in this amp. One is send and the
other is return.
Footswitch Jack - this is a 3 conductor 1/4 jack. This is for hooking up a footswitch to turn on/off the effects section.

Standard Dual Instrument Setup - in this setup one, two or three keyboards or
instruments are plugged into Inputs 1, 2 & 3. (Remember, if you are using pre-amplified
keyboards or a drum machine, we suggest that you turn their output levels to about mid
way up and this will give you a cleaner sound as well as giving you available headroom
for leads.) You can also plug in any combination of keyboards, microphones or guitars.
The multi-instrument setup is especially useful for teaching studios.
Of course, you can adjust the tone controls to any desired sound, but in this setup we
suggest these tone control settings. It will deliver a clear, clean sound that has enough
top end clarity to cut through. Add low and low mid for a beefier presence but be careful
as this can muddy up the sound.
Adjust the Effects section to suit the music or to your taste.

Standard Dual/Triple Microphone Setup - in this setup Lo-Z and two Hi-Z microphones
are plugged into Inputs 1, 2 &3. This is a basic mini-PA system. This can be also be used
for plugging in a CD player or cassette decks and a microphone for karaoke, teaching
studios, small public address or even DJ work. It can be used for singing over prerecorded
tapes with mixing capabilities.
As mentioned earlier, you can adjust the tone controls to any desired sound, but in this
setup we suggest these tone control settings. Of course it depends on the listening
environment. It will deliver a clear, clean sound that has enough top end clarity to let the
voices cut through.
Adjust the Effects section to suit the music or to your taste. In public address work, you
usually dont use Chorus or Delay unless you are singing.
