The VRX918SP input panel features analog audio inputs and sophisticated onboard digital signal processingtechnology. Precision Bandpass limiting and automatic self-protection functions ensure maximum performance.CONTROLS1. AUDIO OUTTwo-position push-button DSP preset selection switch,enables an 80Hz Hi-Pass filter (graph 1) or direct loopthrough (graph 2) to the audio output. When set to the“Hi-Pass 80Hz” position, the signal leading to theAUIDIO OUT connector is shaped in such a way (graph 1)that allows a smooth transition to a connected full rangespeaker, crossed over at 80Hz.(The Hi-Pass frequency is fixed at 80Hz)When connecting to a second VRX918SP sub wooferset the switch of the first subwoofer to bypass and thelast subwoofer to Hi-Pass, so that the last subwooferin the signal chain provides the xover to the full rangesystem.2. SUB WOOFER LO-PASSTwo-position push button DSP preset selection switch,engages either an 80Hz or 120Hz Lo-Pass filter (graph 3).The default 80Hz position is recommended. The120HzLo-Pass filter option becomes useful when externalsignal processing is used or if the low frequency extensionof the companion full range system does not reach 80Hz3. ATTENUATIONDetented rotary input sensitivity control attenuates level in 0.5 dB steps. The Input Sensitivity is +4 dBUnominal (+20 dBU clip) with the control fully counter clockwise, and -10 dBV nominal (+4 dBU clip) withthe control fully clockwise. (Note: Professional mixing boards with XLR outputs should use the fully counter-clockwise position as a starting point. Whereas semi-professional equipment with 1.4 inch jack’s, RCAconnectors and unbalanced sources should start at the middle position - watch for clipping (peak LED)!4. RESETPress to reset line voltage circuit breaker.5. LINE SELECTTwo-position slide switch, set to 115V position for (100-120V~) or 230V position for (220-240V~) operation.123678451112910VRX918SP INPUT PANELgraph 1graph 31780Hz80Hz 120Hzgraph 2AudioOutAudioOut
