INPUTS & SIGNAL PROCESSING MIC Line UNITS Input figures quoted at maximum front panel gain control setting. INPUT 1 & 2: (mic/Line) 3 way, 3.5mm phoenix, balanced, suitable for up to 600Ohm microphones or line level. Input impedance 8,700 8,700 ? Sensitivity -69 -45 dBu Overload -33 -9 dBu 100V: Isolated 100V line input Input impedance 120,000 ? Sensitivity +11 dBu Overload +47 dBu AGC: Compression of signal indicated by green INPUT LED when active and RED when overloaded. Input range >36 dB Output range ±1 dB Min. input level for AGC See sensitivity Attack time 3.5 ms Decay time 1.4 s METAL LOSS CORRECTION: Specially designed adjustable filter to compensate for the effects of metal loss. Gain @ 1kHz remains constant. Min. slope 0 dB/oct. Max. slope +3 dB/oct. LOOP IND: High shelf filter options to compensate for the effect of loop inductance on the class D output stage Low No effect Med 3dB max starting from ~1kHz High 4.8dB max starting from ~1kHz Test Signals: Internally generated signals for commissioning which when activated interrupt the input audio signal. Off Audio signal passed Field Single 1k tone Hz Freq Combined 100, 1k & 5k sine tones Hz DC Power Power figures for reference only. With unit set for maximum output with the input in AGC. Only use the provided DC power supply. Voltage 24 V Current idle 0.28 A Current pink noise 1.3 A Current sine 3.2 A OUTPUTS UNITS LOOP OUTPUT: 2x 2way, 5mm, phoenix.
