One model can be powered from ac lines between 90 Vac and 126 Vac, 50/60 Hz. The other can be powered from ac lines between 198 Vac and 252 Vac, 50/60 Hz. 1.1 90-126 Vac, 50/60 Hz Operation The mixer is provided with its voltage select switch on the back. For ac lines of 90 Vac to 110 Vac, use the 100 V setting. For ac lines of 108 Vac to 126 Vac, use the 120 V setting. 1.2 198-252 Vac, 50/60 Hz Operation The mixer is provided with its voltage select switch on the back. For ac lines of 198 Vac to 231 Vac, use the 220 V setting. For ac lines of 216 Vac to 252 Vac, use the 240 V setting. WARNING: Verify that the volt- Table I. Line Fuse age select switch is in the desired position for the intended ac line voltage BEFORE applying power to the mixer. Verify the proper fuse value is installed by referring to Table I. 2 VENTILATION The mixer should not be used in areas where the ambient temperature exceeds 60°C (140°F). During use care should be taken to keep air flowing past the heatsinks on the back of the mixer. 3 SIGNAL CONNECTIONS 3.1 Input Connections Balanced microphone inputs may be made to the 3-pin XLR-type connectors on the rear of the chassis. Unbalanced line inputs may be made to the Vi-inch phone (TS) connectors. The signal should be input on the tip and common on the sleeve of the 1/4-inch phone connector. 3.2 Output Connections All outputs of the mixer are unbalanced. The signal is on the tip and common is on the sleeve of the Va-inch phone connectors. 4 FEATURES 4.1 Input Channel (Refer to Figure 1.) The input channel is the starting point of the mixer. Each input channel will accept one signal source which may then be equalized, have reverb or other effects added, sent to a monitor system, and/or sent to the main system for the audience to hear. AC Line Voltage AC Line Fuse 90-126 V 198-252 V 3.0 A 1.6 A Each input has a low-impedance mic input (3-pin female XLR-type connector) and a high-imped-ance unbalanced mic/line input (’/«-inch phone jack). The line input will accept signals from an instrument, high-impedance microphone, tape deck, drum machine, or almost any other audio source. Always be sure that the channel fader or master faders are down before plugging or unplugging input sources. 1. Gain: This control adjusts the gain or amplification of the input amplifier. This is necessary to accommodate the wide variation in signal strength presented to the mixer by the variety of signal sources. The GAIN control allows the amplification of each input source to be optimized. This results in the best signal-to-noise ratio while reducing overload distortion. 2. Monitor Send: This control sets the level of the monitor buss signal from the input channel. It is independent of all input controls except the GAIN control. It is not affected by the channel equalizer controls or the channel fader. Thus, it is not affected by changes in the main mix. 3. EFX/REV Send: This control determines the amount of reverb from the internal spring and/or external effects that are added to the input signal. It is affected by the channel equalizer controls and the channel fader. Since each channel has its own EFX/REV SEND, some channels can have reverb or effects and others none. Note that since the internal reverb and external effects share a common send, they will always have the same sources. That is, it is not possible to have reverb on one input source and effects on another input source at the same time. It is possible to have reverb and effects simultaneously on both input channels. The EFX/REV SEND may also be used as a mono send. For instance, this might be useful for tape recording or a second monitor mix. 4. EQ Controls: Equalization can be simply described as a tone control. The EQ circuits used in the 100M have an immense amount of boost and cut capability. This range can be a bonus when dealing with instrument signals, poor acoustics, or other problems. For best results use them sparingly. three The Electro-Voice 100M Powered Mixing Console 2 3 4B 4C 5 6 LfFWONTTCfl RJGKT/MAJN •?*0 .18 -10 -4 0 3 t..................................-m 100W 10 O UAXJUUU POWER [Q I n GAIN MONITOR Ô O EFX/FtEV la- 0 ow'*---♦** PAN Ö GAIN MONTOR o o •-10 EFX/REV MO ti lCW’*-•« PAN 12S 2&0 600 IK 2K 4X ftK 1 «3 126 260 *00 IK 2X 4K IK -412----- LEFT/MONfTOR RIGHT/MAIN MONITOR Q PAN MONITOR Q Q PAN MONITOR -f- -a- - / J i f f / / / / / SUB L f SUB R 19 17 cy Ô phantomO POWER 43 V EFXSEND REVUEVEL Ô 42- EFX RETURN REV EQ -, 13 14 7igure 1.
