00 kilohms. Output level across a bal-
anced 600 ohms shall be 8dBm/2V. Input sensitivity at full
output shall be 50mV or less; hum and noise shall be at least
-72dB below rated output. Inputs shall be via RCA-type
phono jack or screw terminal strip. Output shall be via
screw terminals.
The unit shall operate from
1
20V AC, 60Hz and shall con-
sume 4 watts.The unit shall measure 5-

power cord shall be provided.
GA6A
The amplifier shall be a Bogen Model GA6A, or equivalent,
capable of delivering 6 watts at not more than
1
% total har-
monic distortion from 75Hz to
1
5kHz. Frequency response
shall be 30Hz to
1
2kHz, +0dB, -3dB.The amplifier shall pro-
vide one low-impedance, balanced or unbalanced micro-
phone input and one high-impedance auxiliary input, with
individual front panel controls and mixing capability.
Microphone dynamic range shall be 46dB with mic sensitiv-
ity of 0.3mV Auxiliary input sensitivity shall be 0.2V or bet-
ter. Hum and noise shall be -50dB for microphone, and
-64db for auxiliary inputs.Tone adjustment shall allow 9dB
treble boost or attenuation at
1
0kHz, located on rear panel.
Outputs shall be provided on the rear panel for 8-ohm
speaker and 25V and 70V lines. Output and microphone
connections shall be made at rear-panel screw terminals;
auxiliary input shall be via a rear panel RCA-type phono
jack.
The amplifier shall operate from
1
20V AC, 60Hz, and shall
consume
1
6 watts. A rocker-type, front panel-mounted
switch shall illuminate when the unit is switched on.
Overload protection shall be by means of a thermally-actu-
ated circuit breaker and a replaceable fuse.The chassis shall
be constructed of zinc-plated galvanized steel with protec-
tive epoxy, and the cover from black vinyl-clad cold-rolled
steel.The front panel shall be finished in black.The unit shall
measure 8-
