Boasting a hefty 75 watts per channel, the VSI 75 offers listeners an introduction into the world of Audio Research, and the magic sonic ability it brings.

Audio Research VSI 75 Integrated Amplifier

The VSi75 integrated amplifier breaks new ground in an ‘all in one’ product design, and sets a new benchmark in the lifelike reproduction of music. The VSi75 continues the design series of ‘open chassis’ products from Audio Research such as the VSi60 and VS115, yet incorporates new developments from the Reference series product to combine in a visually striking and sonically astonishing product.

Specifications
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 KT150-Power Output; 2 -6H30 driver.
