Warranty - Audio Research FOUNDATION Series Manual

Warranty

Audio Research Corporation products are
covered by a 3-Year Limited Warranty or a
90-Day Limited Warranty (vacuum tubes).
This Limited Warranty initiates from the date
of purchase, and is limited to the original
purchaser, or in the case of demonstration
equipment, limited to the balance of
warranty remaining after original shipment
to the retailer or importer.
In the United States, the specific terms,
conditions and remedies for fulfillment
of this Limited Warranty are listed on the
warranty card accompanying the product
in its shipping carton. The warranty terms
are also available on the internet at www.

warranty-statement. Outside the United
States, the authorized importing retailer or
distributor has accepted the responsibility
for warranty of Audio Research products
sold by them.
The specific terms and remedies for
fulfillment of the Limited Warranty may vary
from country to country. Warranty service
should normally be obtained from the
importing retailer or distributor from whom
the product was purchased.
In the unlikely event that technical service
beyond the ability of the importer is required,
Audio Research will fulfill the terms and
conditions of the Limited Warranty. Such
product must be returned at the purchaser's
expense to the Audio Research factory,
along with a photocopy of the dated
purchase receipt for the product, a written
description of the problem(s) encountered,
and any information necessary for return
shipment. The cost of return shipment is the
responsibility of the purchaser.

VT80 SE Specifications
POWER OUTPUT: 75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic
distortion typically 1% at 75 watts, below 0.05% at 1 watt. (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) 7Hz to 60kHz.
FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.7Hz to 80kHz.
INPUT SENSITIVITY: 1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)
INPUT IMPEDANCE: 300K ohms Balanced (150K ohms SE).
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT TAPS: 8 ohms, 4 ohms.
OUTPUT REGULATION: Approximately 1.0dB 8 OHM LOAD TO OPEN CIRUCIT
(Damping factor approximately 8).
OVERALL NEGATIVE FEEDBACK: 15dB
SLEW RATE: 10 volts/microsecond
RISE TIME: 4.0 microseconds
CHANNEL SEPARATION: 112dB
HUM & NOISE: –84dBV weighted, 8 ohms tap
SIGNAL TO NOISE: 112dB
CONTROLS: Power on/off, auto shut-off on/defeat, Input BAL/SE, RS232, 12V trigger
