SERVICE

Make sure to save your sales receipt. It’s useful in establishing when you bought the mixer and for insurance purposes if someone happens to borrow your entire studio while you are on vacation in Mazatlan.

TROUBLESHOOTING

We haven’t included a gigantic trouble-

 

shooting chart with circles and arrows and

 

captions on the back because our Service

 

Department and support persons are here to

 

handle that sort of thing. Still, there are

 

some simple tests you can make before you

 

call to determine if your MS 1202 is really

 

the culprit. This saves time all around and

LEVEL

prevents you from feeling sheepish when it

turns out that it’s really your Blort-Tronics

SETTING

Sonic Defrabulator that’s creating the prob-

STEPS

lem, and not our mixer.

 

Problem: Dead Input

 

Are the gain controls turned up? (Honest,

TECH

this happens.)

STUFF

Unplug all Channel Insert hook-ups.

 

Try the same instrument and cord in

 

another channel.

 

Problem: Dead Output

 

Are the gain controls turned up?

 

Unplug all Channel Insert hook-ups from

 

the mixer.

 

Switch output cords. For example, if the

 

left output is dead, switch the left and right

 

output cords at the mixer. If the problem

 

moves to the right, it’s not the mixer.

 

Problem: Noisy Output

 

Turn all gain knobs and AUX returns

 

down. If the noise goes away, bring levels

 

back up one at a time, checking for noise at

 

each step.

 

Unplug everything except the output

 

where the noise was detected. If the noise

 

goes away, plug everything back in one at a

 

time, checking for noise at each connection.

 

Problem: No Power

 

Check the MS 1202 fuse (see page 7).
