All AUX controls are “post-EQ/post-fader,” meaning that their signal is derived from a point after the channel EQ stage and fader. This means that the AUX signal is affected by the channel EQ and fader settings. 0 PAN Control The PAN controls assign the signal from the corresponding channel to any desired position in the "stereo sound field.” If a PAN control is set to the maximum “L” (LEFT) position, the signal from that channel will appear only at the left-channel output (ST OUT L). If the PAN control is set fully “FT (RIGHT), the signal will appear only at the ST OUT R output jack. If a PAN control is set to its center position, then the signal from that channel will appear equally at both the left- and right-channel outputs, and the sound will appear at the center of the stereo sound field (at a point midway between the two stereo speakers). Other PAN control settings place the sound at positions roughly corresponding to the PAN control setting by varying the level of the signal sent to the left- and right-channel outputs. : - : LEFT RIGHT “ SPEAKER SPEAKER \l/ \l/ /|\ \l/ 0 Channel Fader This is the main level control for each input channel. It determines the level of the signal sent from the corresponding input channel to the master stereo buss. The settings of the input channel faders determines the “mix” or balance of sound levels between the instruments or other sources connected to the inputs. NOTE: -- If a channel is not being used, its fader should be set to the minimum position to prevent unwanted noise from being added to the main program signals. -3 - • Master Control Section O AUX SND Controls These adjust the overall output level of the AUX 1 and AUX 2 “mixes” set up using the corresponding channel AUX controls. AUX SND 1 sets the overall level of the AUX 1 mix signal appearing at the AUX SND 1 jack, and AUX SND 2 sets the overall level of the AUX 2 mix signal appearing at the AUX SND 2 jack. These controls should be used to optimally match the AUX SND output level of the mixer to the input sensitivity of the external signal processing device or power amplifier used. O AUX RTN Controls These controls adjust the level of the signal received at the corresponding rear-panel AUX RTN jacks and mixed into the main program on the master stereo buss. Stereo inputs are provided for each AUX RTN input, providing compatibility with the many mono-in/ stereo-out signal processors currently available. 0 MASTER Fader The MASTER fader controls the master output levels of both the left and right channels, and thus the level of the signals appearing at the ST OUT L and R jacks. PHONES Control Adjusts the level of the master stereo program signal applied to the rear-panel PHONES jack. Use the PHONES control to set the most comfortable headphone monitoring level. Level Indicators The AM602 has left- and right-channel SIGNAL and CLIP LEDs. The SIGNAL LEDs light when a signal of sufficiently high level is detected in the corresponding channel, and the CLIP LEDs will light if the signal in the corresponding channel reaches a level 3-dB below clipping. If the either of the CLIP indicators lights more than just occasionally on high-level peaks, the fader levels or levels of the sources connected to the mixer’s inputs should be reduced to prevent possible overload distortion. ® POWER Switch (Rear panel) Flip to the ON position to turn power ON, or to the OFF position to turn power OFF. The POWER indicator LED will light when the power switch is turned ON. - CAUTION: -- Make sure the MASTER fader is set to minimum when turning the POWER switch ON. ' CONNECTORS INPUT Connectors The AM602 has a total of 6 input channels, each of which has a single 1/4" monaural phone INPUT jack. See “© MIC/LINE Switch” for a description of the MIC/LINE switches associated with INPUT jacks 1 and 2. When a MIC/LINE switch is set to MIC, the input level and impedance for that channel are set to -50 dB/50—600 ohms. When set to LINE, the input level and impedance are -10 dB/600 ohms. The input level and impedance for INPUTS without MIC/LINE switches are -10 dB/600 ohms. AUX SND Jacks These jacks deliver the AUX 1 and AUX 2 mixes, respectively, to feed an external signal processor, a monitor system, etc. Nominal output level and impedance of the AUX SND jacks are -10 dB/10 kohms. ® AUX RTN Jacks The output from signal processors fed by the AUX' SND jacks can be returned to the master stereo buss via these jacks. Stereo AUX RTN jacks offer compatibility with the wide range of mono-in/stereo-out signal processors currently available. The AUX RTN jacks can also be used to add external signals other than the output from signal processor to the stereo buss. Nominal input level and impedance are -20 dB/600 ohms. ® PHONES Jack The PHONES jack delivers the mixer’s master stereo program signal to a pair of standard 8 ohm stereo headphones. The PHONES control adjusts the headphone monitoring level. ...
