Samson Power Amplifier Servo 4060 - Manual (Page 2)

The power amplifier, being of four channels, shall
deliver a minimum of 60 watts into loads of 4 ohms, or
120 watts into loads of 8 ohms when in the bridged
mode, or 120 watts + 60 watts + 60 watts (one side
bridged). It shall be passively cooled, and shall have inter-
nal short-circuit and thermal protection circuitry. A pro-
tection LED indicator shall activate and the power amplifi-
er shall disconnect the amp loads to protect against short
circuits, overheating, severe overcurrent conditions or DC
offset present at the outputs. The power amplifier shall
have slow start-up and muted inputs on turn-on. Inputs
shall be on 1/4
″
Tip-Ring-Sleeve balanced phone connec-
tors and unbalanced RCA gold-plated connectors. Outputs
shall be on insulated binding post connectors.The front
panel shall have 4 independent level controls, each with a
level indicator, a master power switch and amplifier pro-
tection LED.
The power amplifier shall have a frequency response
of 10 Hz to 85 kHz (-3 dB), signal-to-noise equal to or
greater than 103 dB and THD less than 0.03%. Total
power consumed at full audio power shall be 360 W (120
Vac/60 Hz) and 395 W (220 Vac/50 Hz)). The dimensions
shall allow for standard 19
″
EIA rack mounting or 17.5
″
(444 mm) wide without rack ears. It shall be 3.25
″
(82.5
mm; 2 rack spaces) high and 10.75
″
(273 mm) deep.
Weight shall be 25 lb. (11.3kg). The power amplifier shall
carry a three-year warranty.
The power amplifier shall be a SAMSON SERVO 4060.
