Keep This Manual For Future Reference. FCC INFORMATION (U. S. A. ) 1. IMPORTANT NOTICE: DO NOT MODIFY THIS UNIT! [. . . ] The indicator will light red when the level reaches +17dB to warn that clipping is imminent. r r t t e Equalizer Provides +/-15dB of control over high, mid and low frequency ranges at the center frequencies listed below. HIGH : 10kHz (shelving) MID : 2. 5 kHz (peaking) LOW : 100Hz (shelving) Frequency response will be flat when the knob is positioned at "G". +20 +15 +10 y u Response [dB] i i +5 0 ­5 ­10 ­15 ­20 20 100 1k Frequency [Hz] 10k 20k o r AUX1, AUX2 Controls t POST Switch Individually controls the level of the signal sent from each channel to the AUX1 and AUX2 buses. The signal taken from before the channel fader is sent to AUX1. Depending upon the POST switch setting, the signal taken from either before (POST Switch = ?) or after (POST Switch = >) the channel fader is sent to AUX2. When a stereo channel is used, L and R signals are combined and sent to the AUX1 and AUX2 buses. MV12/6 -- Owner's Manual 4 Front & Rear Panels y EFFECT Control Controls the level of the signal sent from each channel to the EFFECT bus. This control is located after the channel fader so its level will also be affected by the channel fader setting. When a stereo channel is used, L and R channel signals are combined and sent to the EFFECT bus. u PAN Control (CH1-8) BAL Control (CH9-12) The PAN control knobs set the position within the stereo field of each signal that is sent to the GROUP bus 1-2, GROUP bus 3-4 and STEREO bus L-R. The BAL control knobs set the balance between left and right channels and assigns the signals that are received at INPUT L (CH9, 11) to GROUP buses 1/3 or STEREO bus L, and the signals received at INPUT R (CH10, 12) to GROUP buses 2/4 or STEREO bus R. i GROUP, ST Select Switches Used to send the signal of each channel to the GROUP bus 1-2, GROUP bus 3-4 and STEREO bus L-R. · ON Switch Switches the built-in digital effect ON (>) or OFF (?). When set to OFF, the signal from the built-in effect is not sent. · AUX1, AUX2 Control Controls the level of the signal that is sent from the built-in digital effects to the AUX1 and AUX2 buses. · GROUP/ST Control Controls the level of the signal that is sent from the built-in digital effects to GROUP buses 1-4 and the STEREO bus. · GROUP, ST Select Switches Sends the signal from the built-in digital effects to GROUP buses 1-4 and the STEREO bus. When the switch is ON (>), the signal is sent to its corresponding buses. i TAPE IN Control Controls the level of the signal that is sent from the TAPE IN jack to the STEREO bus. o ST GRAPHIC EQUALIZER A stereo 7-band graphic equalizer that offers tone adjustment to the signal that is output to the ST OUT jacks. A +/-12dB boost or cut is provided at each of the frequency bands 125, 250, 500, 1k, 2k, 4k and 8kHz. !0 PHONES/MONITOR Output and Meter Select Switch Selects the signal that is sent to the MONITOR jack, PHONES jack and the level meter. The three switches are used in combination to select TAPE IN, ST, GROUP 1-2 and GROUP 3-4 signals. Signal TAPE IN ST GROUP 1-2 GROUP 3-4 ?? !1 PHONES/MONITOR Control Controls the level of the signal that is sent to the MONITOR jack and PHONES jack. !2 PHONES Jack This is a stereo phone type jack for connecting a pair of headphones (nominal output/impedance of 3mW/40). Use the !0 PHONES/MONITOR output and meter select switch to select the source to be monitored with the headphones. !3 LEVEL Meter The LEDs indicate the output level of the signal selected with the PHONES/MONITOR output and Meter Select Switch !0. "0" indicates a nominal level, and the PEAK indicator will light when clipping is imminent. !4 POWER Indicator The indicator will light when the main unit's power is ON. !5 LAMP Connector A XLR type lamp (AC or DC12V, 0. 5A Max) can be attached here.

The fader's "0" position is an average level. t Use the volume control on the power amp to adjust the speaker's volume. If it is necessary, use monitor devices (a pair of headphones, monitor speaker, etc. ) or recording devices.
