Audio:
•Input Signal Types: Balanced or unbalanced analog line-level
•High-Pass Filter(70 V and 100 V operation only): -3 dB @ 80 Hz, -12 dB/octave
•THD+N: <0.1% at 1 kHz @ -3 dB full rated output power
•Crosstalk: -75 dB at 1 kHz
•Input Sensitivity: 1.23 Vrms, +4 dBu balanced; 0.316 Vrms, -10 dBV unbalanced; For 150 W (8 Ohms), 300 W (8 Ohms Bridged), 300 W(70 V/100 V)
•Gain: 29 dB @ 8 Ohms
•Protection: Over current, under voltage, over temperature, DC offset, extreme high frequency
•Go to Sleep Time: 25 minutes with no signal present (when set to POWER SAVER)
•Wake Time: 0.5 s typical
•Wake Threshold: 0.44 mV typical
Connectors:
•CH1-CH4: (2) 4-pin 5.08 mm pitch, 12 A plug with screw locking retainers; Power amplifier output; Wire Size: Terminals accept up to 12 AWG (3.31 mm2) NOTE: Output is direct-coupled, not transformer isolated
•AUDIO IN (UNBALANCED): (4) RCA connectors, female; Unbalanced line-level audio inputs (Summing on CH1 + CH2 and CH3 + CH4); Maximum Input Level: 2.24 Vrms, +7 dBV (+9.2 dBu)
•AUDIO IN (BALANCED): (4) 3-pin 3.5 mm detachable terminal block; Balanced line-level audio inputs; Channel pairs 1 - 2 and 3 - 4 can each be configured to operate as stereo channels or a downmixed mono channel; Maximum Input Level: 7.75 Vrms, +20 dBu; Input Impedance: 20k Ohms
•G: (1) 6-32 screw; Chassis ground lug
Controls & Indicators:
•PWR: (1) White/Red LED; White indicates amplifier is on and ready for use; Red indicates amplifier is in standby
•HI-Z: (1) White LED; Indicates when Hi-Z mode is enabled (70 V or 100 V); Channels 1 - 2 and 3 - 4 are bridged and set to 70 V or 100 V operation
•SIGNAL: (4) White LEDs (one per input); Indicates when an active input signal is present
•FAULT: (4) Red LEDs (one per input); Indicates that the input channel is faulted or clipping
•GAIN 1-4: (4) Screwdriver-adjustable rotary controls, one per input channel; Adjusts the input attenuation level for the corresponding input channel
•LoZ Modes: (2) Slide switches, 1 switch for CH1 + CH2, 1 switch for CH3 + CH4; Selects stereo, summed, or bridged operation; STEREO preserves channels 1 and 3 as left, and channels 2 and 4 as right. SUMMED mixes channels 1 and 2 into one channel and channels 3 and 4 into one channel. BRIDGED maps channels 1 and 3 to their respective outputs with higher power of amplification. Channels 2 and 4 are not connected.
•Operations Mode: (1) Slide switch; Sets the amplifier LoZ (4 or 8 Ohm) or Hi-Z operation (70 V or 100 V)
•Power Mode: (1) Slide switch; Selects "Power Saver" or "Always On" operation
Environmental:
•Humidity:10% to 90% RH (non-condensing)
Construction:
•Chassis: Metal, convection cooled (fanless)
•Front Panel: Metal, black finish with polycarbonate label overlay
•Mounting: Freestanding, surface mount, or 1/2 width 1 RU 19 in. rack mountable; gangable with other Crestron modular AMP series products (adhesive feet and surface mounting kit included; ganging kit and rack mounting kit optional)
