The MONITOR control configuration is factory preset to pre-EQUALIZER/pre VOLUME. As a result, the MONITOR signal is independent of the settings of the channel EQUALIZER and VOLUME controls. © VOLUME control The setting of the VOLUME control determines the level of its corresponding source in the mix of the signal levels of all input channel sources. As a precaution, if the channel is not being used, it is recommended that the VOLUME control be set to its minimum position to prevent unwanted noise from being added to the main signal. Master Control Section © TAPE TO MONITOR control The TAPE TO MONITOR control adjusts the level of the signal received from the rear panel TAPE IN inputs (RCA pin jacks TAPE IN 1 and 2). The adjusted signal is then fed to the master MONITOR control and the rear panel MON OUT jack. The TAPE TO MONITOR control selectively determines the output level of tape recorders or other such devices in the MON OUT signal. © TAPE IN control The TAPE IN control regulates the level of the signal sent from rear panel TAPE IN inputs. The regulated signal is then added to the SP OUT, REC. OUT and LINE OUT signals. The TAPE IN control sets the output level of tape recorders or other such devices in the main program signal. When recording from the REC OUT jacks, this control must be set at a minimum to avoid electronic feedback. As a result, recording and playback cannot be accomplished at the same time with one tape machine. © EFFECTS TO MONITOR control The EFFECTS TO MONITOR control adjusts the level of the combined signal received from the rear panel EFF RTN inputs (1/4" phone jacks EFF RTN 1 and 2) before the signal is fed to the rear panel MON OUT jack. The EFFECTS TO MONITOR control selectively determines the output level of external effects in the MON OUT signal. © EFFECTS RETURN control The EFFECTS RETURN control regulates the level of the combined signal sent from the rear panel EFF RTN inputs. The regulated signal is then added to the main program signal. The EFFECTS RETURN control sets the output level of external effects in the main program signal. © EFFECTS SEND control This control adjusts the output level of the overall mix derived from the input channel EFFECTS controls and feeds the signal to the rear panel EFF SEND jack. The EFFECTS SEND control should be used to optimally match the mixer EFF SEND output level to the input sensitivity of the connected external effect or signal processor. © MONITOR control The independent monitor bus features a master MONITOR control for adjustment of the overall monitoring level. This control adjusts the output level of the overall mix derived from the input channel MONITOR controls and feeds the signal to the rear panel MON OUT jack. © MASTER control The output level of the main program signal is regulated by the MASTER control. The regulated signal is fed directly to the rear panel LINE OUT jack and via the graphic equalizer to the rear panel SP OUT jacks. © Graphic Equalizer For precise response shaping of the SP OUT signal, the seven-band graphic equalizer provides 12 dB of boost or cut in each band. There are seven independent linear controls at the standard ISO center frequencies of 125, 250, 500, lk, 2k, 4k, and 8k Hz peaking. 3 © LIMITER indicator EMI620 is equipped with a limiter circuit which can limit the maximum level of signal at the SP OUT to prevent the signal from distorting. The LIMITER indicator is lit when the limiter cirT cuit is activated. © PROTECTION indicator The PROTECTION indicator lights for approximately 6 seconds after the POWER switch is pressed to indicate that the protection circuitry is operating. No sound is output at the SP OUT while this indicator is lit. This indicator will also light and the sound will be cut off at the SP OUT when the protection circuitry is activated at any other time during the amplifier operation due to factors such as a detection of excessive DC voltage at the SP OUT or a thermal overload. When the problem is corrected, the protection circuitry is automatically deactivated, the indicator goes out, and the amplifier resumes normal operation.
