RETURN

jacks and engage the 

BREAK SWITCH

. Instant-

ly, the entire main mix is switched off and the 
intermission entertainment is switched on. 

Even if you just want silence during the 

breaks, this switch can act as a “Master Mute” 
switch, simply by plugging nothing into 

TAPE 

INPUT

 

.

PHONES LEVEL 

After the 

MAIN MIX

 Fader 

, the mix 

is sent through this knob, allowing you to set 
headphone levels as desired without disturbing 
the main mix level.

When a channel’s 

SOLO PFL

 

 is engaged, 

the main mix will be replaced by the solo sig-
nal, allowing the engineer to audition channels 
without disturbing the main mix.

The stereo 

PHONES

 jack 

 can drive any 

standard headphones to very loud levels. Walk-
person-type phones can also be used with an 
appropriate adapter. 

Note:

 Please see the “Safety Instructions” on 

page 2 for information on hearing protection.

UTILITY OUT LEVEL 

After the 

MAIN MIX

 Fader 

, the mix is 

sent through this knob, allowing you to set the 
levels at the 

UTILITY OUT

 

 as desired with-

out disturbing the main mix level.

SUB FADERS 

The typical exit for channel signals is through 

one or more sub mixes. The sub mix signal is 
fi rst controlled by this fader, which provides 10 
dB of gain fully up, unity gain at the “

U

” mark, 

and is effectively muted fully down. 

From here, the signal goes to two very differ-

ent locations: 

SUB OUT

 

 sends the sub mix 

directly out of the mixer via its TRS jacks; and 

SUB ASSIGN

 

 sends it to the 

MAIN MIX

 

Fader 

.

LEFT/RIGHT SUB ASSIGN 

As discussed in 

ASSIGN

 

, the only way to 

get channel outputs to the main mix is via the 
sub mixes, and this switch is the key. 

Continuing the assumption made in 

ASSIGN

 

, Subs 1 and 2 are the left-right stereo path 

from the channels to 

SUB

 Faders 

 

1

 and 

2

with 

SUB 1

 carrying the left signal and 

SUB 2

 

carrying the right. Engage 

SUB 1 ASSIGN LEFT

 

and 

SUB 2 ASSIGN RIGHT

, and you’re done. 

Take a look at the block diagram on page 22 — 
it’ll explain this and more, but in hieroglyphics. 

3.   Slowly turn up the 

MAIN MIX

 Fader 

 

until feedback just begins to occur. BE 
CAREFUL! Feedback can occur quickly 
and become very LOUD, very fast.

4.   Cut the appropriate slider until feedback 

stops.

Suggestions for better sound:

•   For better vocal sound, set the 125, 250, 

and 16K sliders to +5. 

Note:

 Make sure the singer is within 3 to 

6 inches of the microphone. No amount of 
EQ can save a wandering minstrel.

•   For more presence, set the 4K and 8K slid-

ers to +5.

•   To warm up the overall sound, set the 2K 

slider to –5.

•   REMEMBER, LESS IS BETTER.

TAPE LEVEL 

You can adjust the incoming level of your in-

termission entertainment, independent of the 
main mix level controls, via this feature. Here’s 
how: Patch the stereo device into the 

TAPE 

INPUT

 

. Put the device in play. Engage the 

BREAK SWITCH

 

 and set the 

TAPE LEVEL

 

 knob as desired. Assuming the 

MAIN MIX

 

Fader 

 is set, you should hear the device.

BREAK SWITCH 

No, when we say 

BREAK SWITCH

, we’re 

not asking you to break the switch, we’re of-
fering you a very handy feature. When it’s time 
for the talent to take a break, the engineer 
usually wants to stretch his legs. But walking 
away from a live mixer in a crowded club can 
be somewhat unnerving — what if some goon 
starts dinking around with the faders? 

No problem. Just plug in your intermission 

entertainment device to the 

TAPE INPUT
