CIJENA:

TECHNICAL SPECIFICATION:

POWER OUTPUT :
75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt. Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e. if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

POWER BANDWIDTH :
(-3dB points) 12Hz to 70kHz.

FREQUENCY RESPONSE :
(-3dB points at 1 watt) 1.0Hz to 70 kHz.

INPUT SENSITIVITY :
0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)

INPUT IMPEDANCE :
52.5K ohms Single-ended.

INPUTS
(5) 1, 2, 3, 4, 5 (Single Ended RCA connectors).

MAXIMUM INPUT :
10V RMS (any input).

OUTPUT POLARITY :
Non-Inverting (any input).

PUSH BUTTONS :
Volume up, Volume down (103 steps), Power, Input, Mute, Bias. All functions on IR remote control.

OUTPUT REGULATION :
Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).

OUTPUT TAPS :
8 ohms, 4 ohms.

OVERALL NEGATIVE FEEDBACK :
4dB.

SLEW RATE :
10 volts/microsecond.

RISE TIME :
4 microseconds.

HUM & NOISE :
Less than 1.0 mV RMS -88dB below rated output (IHF weighted, Vol down).

POWER SUPPLIES :
Electronically regulated Low and High voltage supplies for input stages. Automatic 40 sec. warm-up/brown-out mute.

POWER SUPPLY ENERGY STORAGE :
Approximately 350 joules.

POWER REQUIREMENTS :
100-125VAC 60Hz (200-250VAC 50Hz) 400 watts at rated output, 600 watts maximum, 210 watts at “idle’ 1.0 watt power off.

TUBES REQUIRED :
2-Matched pair KT120-Power Output; 2 -6H30 driver.

DIMENSIONS :
Width 14.5” (36.8 cm); Height 9.25” (23.5 cm); Depth 16.25” (41.3 cm); Rear connectors extend .88” beyond chassis.

WEIGHT :
16.5 kg Net; 22.4 kg Shipping.
