The amplifier is equipped with a (mic / line) Main Input on either removable connector or XLR or RJ 45 and an Auxiliary Input for music sources (e.g. CD players, tuners, etc.). The amplifier output is available either for low impedance loudspeakers or 100 – 70 V constant voltage line. The amplifier is Class D with switching power supply; the overall weight is extremely reduced plus it offers a wide audio bandwidth quality.FeaturesFull digital technology Power Amplifier 320 W RMSMain input on either removable connector or XLR or RJ 45Main Input can have priority over the Aux InputMain Input has a presence control commandMain Input has a high-pass filter useful for improving speech intelligibilityAux Input for music sources on RCA type connectorAux input with volume and tone controls100 V - 70 V and 4 Ohm outputsFront panel LEDs indicate the device state (ON, PROT), the priority activation (PRIOR) and the signal/peak level (SIG/PK)Amplifier Specifications Power output: 320 W rmsFrequency Response: 50 Hz ÷ 18 kHzDistortion: <0.3%Signal/noise rate: >60 (INPUTS 1-4); >80 (AUX IN) dBCrosstalk: >60 (INPUTS 1-4); >80 (AUX IN) dB Input Section Input sensitivity MIC: -58 dBuInput sensitivity PHANTOM: -21 dBuInput sensitivity LINE: 0 dBuInput sensitivity AUX: -6 ÷ +13 dBuInput impedance MIC: 10 kInput impedance PHANTOM: 5 kInput impedance LINE: 10 kInput impedance AUX: 20 kBass Tone: (80 Hz) ± 8 dBTreble Tone: (13 kHz) ± 8 dBPresence control: ( 2,15 kHz) + 10 dBHigh-pass filter: 150 HzControls: Master volume, Treble, Bass, Gain, PresenceOutput Section Output Loudspeaker Low impedance: 4 Output Loudspeaker Constant voltage: 70 V (31 ) / 100 V (62 )Protections: Overload, Short circuit, Thermal Power Requirementperating voltage: 115-2 30V / 50-60 V ~ HzPower (consumption): 600 W Physical Specifications Height: 88 / 3,4 mm/inchWidth: 444 / 17,4 mm/inchDepth: 220 / 8,6 mm/inchNet weight: 5.5 / 12.12 kg/lbs.
