Product Specifications
Architectural Specifications
The amplifier shall be single channel with an input gain
control and an output level meter on the front panel.
The amplifier shall accommodate an unbalanced high
impedance input, or a balanced low impedance input
with an optional plug-in accessory transformer.
The amplifier shall be capable of delivering a min-
imum of 60 W, continuous sine wave, 20 Hz-20 kHz,
into a 4
Q
load. [6007: The amplifier shall incorporate
an output transformer allowing full power operation,
35 Hz-20 kHz, into an 8 0 , 1 6 Q or 70.7 V line as well
as a direct output terminal for a 4 O load.} [6008: No
output transformer and only a direct output terminal
shall be provided, but it shall be possible to install an
output transformer easily at any time.}
The amplifier shall have < 0.2% THD, 20 Hz-20 kHz,
@ 60 W, direct output. [6007: The amplifier shall have
< 0.2% THD, 35 Hz-20 kHz, @ 60 W, transformer
output.} Frequency response shall be ± 0.5 dB,
20 Hz-20 kHz, @ 1 W. Power bandwidth shall be
10 Hz-40 kHz.
Construction of the amplifier shall be modular. The
entire amplifier circuit, except for the power supply
[6007: and output transformer} shall be mounted on
a single circuit board attached to the heat sink, which
assembly shall be removable from the unit with the
mainframe still mounted in a rack. Cables connecting
the circuit board to the mainframe shall be of a length
sufficient to allow removal of the board without dis-
connection and shall disconnect easily at two plugs.
The amplifier shall occupy three standard EIA rack
spaces and shall operate on 120/240 V A C , 50/60 Hz.
