ARCHITECT’S & ENGINEER’S
SPECIFICATION
The mixer amplifier shall incorporate a 150 W
monophonic amplifier, a 5-band graphic equalizer and a
monophonic mixer with 6 microphone/line-input chan-
nels. Microphone inputs shall be on XLR-type connec-
tors and line inputs shall be on balanced 1/4
″ Tip-Ring-
Sleeve phone connectors. An independent line-level
CD/tape input (routed to channel 6) shall be on phono
connectors. Each channel shall have an aux/reverb send,
2-band equalization and a level control.
The mixer shall provide an effects output on a 1/4
″
phone connector, as well as a preamp out and power
amp in for submix applications on 1/4
″ phone connec-
tors. An effects return shall be provided on a 1/4
′′ phone
connector, and it shall have an independent level con-
trol. Phantom Power of +48 V shall be provided for
operation of condenser microphones. The amplifier shall
be passively cooled. Amplifier output shall be provided
on two 1/4
″ phone connectors. Indicators shall be pro-
vided for peak level (3 dB before clipping), power and
amplifier protection. The unit shall be of a rack-mount
type.
The amplifier shall deliver maximum power equal
to or greater than 150 W into 4 ohms, signal-to-noise
equal to or greater than 95 dB, THD less than 0.1% and
frequency response of ±3 dB from 20 Hz to 50 kHz. The
mixer shall have residual noise of 70 dBu, signal-to-noise
equal to or greater than 70 dB and THD less than 0.03%.
Total power consumed at 1/8 audio power shall be 134
W (115 Vac). Dimensions shall be 19
″ (480 mm) wide,
9
″ (230 mm) deep and 3.5″ (88 mm; 2 rack spaces)
high. Weight shall be 17.6 lb. (8 kg). The mixer amplifier
shall carry a three-year warranty.
The mixer amplifier shall be a SAMSON S62.
