Appendix A: Service Information
Poor sound
• Is it loud and distorted? Make sure that you’re not
overdriving a stage in the signal chain. Verify that
all level controls are set properly.
• Are the input connectors plugged completely into
the jacks? Be sure all connections are secure.
• If possible, listen to the signal source with headphones
plugged into the preamp stage. If it sounds bad there,
it’s not the M•Caster Live.
Noise / Hum / Buzz
• Check the signal cable between the computer/mixer/
MP3 player/phone and the M•Caster Live. Make
sure all connections are secure. These problems
usually produce crackling noises, hum, or buzz.
• Make sure the signal cable is not routed near AC
cables, power transformers, or other EMI sources
(including wall warts and line lumps!). These sources
usually produce hum.
• Is there a light dimmer or other triac-based device
on the same AC circuit as the M•Caster Live?
Dimmers cause buzzing noises. Use an AC line
filter or plug the M•Caster Live into a dierent
AC circuit (or use the USB connection instead!).
• If possible, listen to the signal source with headphones
plugged in. If it sounds noisy there, it’s not the
M•Caster Live.

Troubleshooting
No power
• Please note that M•Caster Live’s USB (computer)
connection [#5] is audio only. It is not a source
of power.
• Our favorite question: Is it plugged in?
Make sure the outlet is live.
• Our next favorite question: Is the power switch on?
Gotcha. There is no power switch, but...
• Make sure the power cord is plugged all the way into
the AC outlet (if utilizing the wall wart). Or make sure
that the USB cable is connected securely to their
respective USB jacks.
• Are any of the input selector switch LEDs illuminated?
If not, make sure the AC (or USB) outlet is live.
If so, refer to “No sound” below.
• The internal AC line fuse may be blown. This is not
a user serviceable part. If you suspect the AC line
fuse is blown, please see the "Repair" section next.
No sound
• Do the input selector switches have the correct
source(s) selected?
• Is the level knob for the input source turned all the way
down? Verify that all the volume controls in the system
are properly adjusted.
• Is the signal source turned up? Make sure the signal
level from the computer, mixer, MP3 player, phone
(or whatever device immediately precedes
the M•Caster Live) is high enough to produce sound.
• Speaking of computers, if one is connected
to the M•Caster Live, make sure () that the cable
is plugged in to the correct jacks and (2) that the input
and output is changed to ‘M•Caster Live’ via Settings
on the computer.
