CONTROLS AND CONNECTIONS (5) CHANNEL PEAK LED The Peak LED illuminates when a channel input is overloading. (5) It detects the peak level after the Equalizer Controls (6) and (4) will light just before clipping to warn that the signal is approaching overload. You do not want the Peak LED to light except very intermittently. If it lights persistently, reduce the Gain Control (4). If the Gain control is set to minimum, the (6) output level of the preceding equipment should be lowered.
CONTROLS AND CONNECTIONS 2. MASTER AND EFFECTS SECTION (23) (24) (13) bus or the internal DSP Echo Effects. The channel Effects Send control is mono, post-EQ, and post-Ch Volume meaning the signal level sent to the Effects Send bus will be affected by the Channel Volume Control (11) setting. For almost all effects send purposes, post-volume is desirable so that when a Ch Volume level is adjusted, any reverb send from that channel follows the volume.
CONTROLS AND CONNECTIONS can be used to maintain proper levels. When set to Main Left & Right, the top red Peak LED will light when the powered output signal is just below clipping. It is acceptable if the red LED lights occasionally. If the red LED lights more than occasionally, you should turn down the Main Left & Right Volume Faders (19) to avoid audible distortion and clipping, which can cause damage to your speakers and even the internal amplifier.
CONTROLS AND CONNECTIONS 4. REAR PANEL This mono unbalanced 1/4” jack outputs the channel signals which can be adjusted by the Effects Send Controls (7 & 12). (36) (28) EFFECTS RETURN INPUT This mono unbalanced 1/4” jack enables convenient inputs to the Effects Channel. If you connect a signal to the return jacks, the signal will be routed to the effects Channel Volume Control (11).
