UP 2162 is a device with 2 separated and independent 160 W amplifiers, each having 2 audio inputs, of which one with priority function through a closing contact. Both the audio inputs are at ‘line’ level: for pre-amplified signals or music sources (e.g. CD players, tuners, etc.).The amplifier output is available either for low impedance loudspeakers (min. 4 ) or 100 – 70 V constant voltage line (for loudspeakers having 100 – 70 V transformers). The amplifier is Class D with switching power supply; the overall weight is extremely reduced plus it offers a wide audio bandwidth quality.FeaturesPower Amplifier designed for the transmission of announcements and / or musical programmesMain input on removable connectorAUX Input for music sources removable connectorControls for treble, bass and Gain on the AUX InputMain Input can have priority over the Aux Input (by means of an external command linked to the removable connector)Output speaker available either for low impedance loudspeakers (min. 4 ) or 100 – 70 V constant voltage lineFront panel LEDs indicate the device state (ON, PROT), the priority activation (PRIOR) and the signal/peak level (SIG/PK)Amplifier Specifications Power output: 2 x 160 W rmsFrequency Response: 50 Hz ÷ 18 kHzDistortion: <0.3%%Signal/noise rate: 80 dBCrosstalk: 80 dB Input Section Input sensitivity LINE: 0 dBuInput sensitivity AUX: 0 ÷ -20 dBuInput impedance LINE: 20 kInput impedance AUX: 20 kBass Tone: (100 Hz) ± 8 dBTreble Tone: (10 kHz) ± 8 dBControls: Master volume, Treble, Bass, GainOutput Section Output Loudspeaker Low impedance: 4 Output Loudspeaker Constant voltage: 70 V (31 ) / 100 V (62 )Protections: Overload, Short circuit, Thermal Power Requirement Operating voltage: 115-2 30V / 50-60 V ~ HzPower (consumption): 2 x 350 W Physical Specifications Height: 88 / 3,4 mm/inchWidth: 444 / 17,4 mm/inchDepth: 220 / 8,6 mm/inchNet weight: 7 / 15.43 kg/lbs.
