100M ENTERTAINER STEREO MIXER
OWNER'S MANUAL
The signals at the GRAPHIC EQ OUT jacks are line
level to drive power amplifiers and other line-level
devices.
The AMP IN jacks require line-level signals (+ 8 dBu
for amplifier clipping).
Use shielded cable for all connections at this point.
9. AC POWER REQUIREMENTS AND FUSE IN¬
FORMATION
***CAUTION***
Hazardous voltages and currents may be en¬
countered within the chassis. The service infor¬
mation contained within this document is for use
by Electro-Voice authorized warranty stations
and qualified service personnel only.
The 100M can operate on 100,120, 220 or 240 V ac,
50/60 Hz.
For 90-110 V, 60 Hz, use the 100-V setting (Japan).
For 108-126 V, 60 Hz, use the 120 V setting. For 198-
231 V, 50/60 Hz, use the 220-V setting. For 216-252
V 50/60 Hz, use the 240-V setting.
Replace the ac mains fuse with a 3-A Slo-Blo, type
MDL 3 fuse only (Export models, refer to the fuse data
label on rear of the unit). Repeated fuse blowing is a
sign of internal trouble and will only be aggravated
by replacing the blown fuse with one of larger value.
10. POWER ON/OFF SWITCH: Turns the entire
100M on and off.
11. PHANTOM POWER SWITCH: The PHANTOM
POWER switch controls the interna! 48 V phantom
power supply. Phantom powering is a compatible
system, that is, normally used dynamic microphones
may be used along side phantom powered con¬
denser microphones without damage.
Phantom powering imposes certain demands on
cables and microphones used. Since microphone
cables carry the electrical power that operates the
microphones, all solder connections within the mic
connectors must be of the highest quality. Otherwise,
extraneous noise may occur.
Some microphones may exhibit random noise
(cracking, sputtering or popping) when used in a
phantom-powered system. This problem is due to
the transformer or the microphone cartridge
developing a leak to the case. The leakage causes
the noise, not the phantom power. Possible solu¬
tions:
A. Turn off the phantom power.
B. Replace the mic.
C. Repair the mic.
Be careful not to plug in or unplug microphones with
phantom power present. Always turn the channel
fader or the master down before plugging in or un¬
plugging microphones to avoid loud, unpleasant
noises which could be harmful to speakers.
12. POWER AMPLIFIER ASSIGN MODE SWITCH:
This switch controls the assignment of the 10OM's in¬
ternal graphic equalizers (and amplifiers, if not reas¬
signed by patching). In the Stereo mode, the Left
equalizer is assigned to the Left stereo output, while
the Right equalizer is assigned to the Right stereo
output. In the MONITOR/MONO mode, the Left
equalizer is assigned to the MONITOR output, while
the Right equalizer is assigned to the MONO output.
13. REVERB FOOTSWITCH JACK: The REVERB
Footswitch jack allows the internal reverb to be
switched on and off remotely from the 100M. Use any
footswitch that connects the phone plugs hot wire to
ground (this includes 99% of all standard
footswitches). The footswitch cable does not need to
be shielded. The reverb is switched on when the hot
wire is grounded.
14. HEADPHONE JACK: The HEADPHONE jack is
located on the rear panel. It monitors the outputs of
the internal power amplifiers. It is suitable for stereo
phones with a rated impedance of 8 to 20,000 ohms.
