Stereo Aux Input Module (SAX1R): The SAX1R module is a stereo, high-impedance, unbalanced input module. It has two RCA jacks for its input connectors, and a gain/trim control that allows the gain to be adjusted up to +6 dB relative to 0 dB nominal gain. It has the ability to mute lower priority modules and be muted by higher priority modules. The module is able to assume any of 4 priority levels. It has a continuously variable ducking control that enables attenuation of the input signal from a minimum of 10 dB to a maximum of 48 dB relative to the normal unmuted condition and a gradual fade back from mute when the mute control is deactivated. The module has a VOX/gating circuit to control muting of lower priority modules and its internal gating circuit, with separate controls for gate threshold and duration. It has bass and treble controls with cut or boost of 10 dB at 100 Hz and 10 kHz, respectively. The module’s output is assignable to either or both of two mixing buses. It allows stereo sources to be mixed into mono and sent to either or both of two mix buses.Bogen Communications SAX1R Features:Gain/Trim controlBass& Treble controlsGate feature mutes lower priority modulesMute send& receiveVariable ducking level when mutedFade back from muteStereo-to-mono summing option4 Priority levelsBus assignableRCA connectorsBogen Communications SAX1R Specifications:Gain: 0 dB to 6 dBFrequency Response: +0/-3 dB, 5 Hz - 100 kHzS/N (20Hz - 20kHz): -100 dBVDistortion:Input Impedance: 50k ohmsTone: ±10 dB @ 100 Hz& 10 kHzDucking (level): -10 dB to -48 dBGate Threshold: 3 mV to 30 mVGate Duration: 0.5s to 5sPriority: Four levelsControls: Gain, Bass,Treble, Ducking, Gate Threshold,Gate DurationConnector: RCA typePower: ±24 V DCDimensions (W x H x D): 1-3/8" x 3-1/8" x 3-1/2"Weight: 2.6 oz.
