Model S-9400 Solid State Stereo/Dynaquad Amplifier
The perfect
match for the S-2400 tuner. Model S-9400 represents true superiority in
features, flexibility and specifications. Inputs for two phonos, microphones,
two auxiliary inputs, tape deck plus 4-channel decoder (or a second tape deck).
Power output of 100 watts RMS (8 ohms, both channels driven at 1 kHz) is
outstanding. And built-in Dynaquad Four-Channel matrixing circuit offers
thrilling 4-channel sound. Distinctive styling matches the S-2400 tuner (the
walnut case is included at no extra
charge)
Design
Features
160 watts of
power (IHF) at 8 ohms, 50 + 50 watts (RMS) at 8 ohms (at 1 kHz); 40 + 40 watts
from 20 - 20,000 Hz. Direct coupled output circuitry. 3 stage preamp section
with FET for improved overload equalization accuracy. Instant overload
protection (power monitoring relay electronically disconnects speakers if any
D.C. potential is detected thus eliminating any damage to amplifier or
speakers.)
Control
Features
Master
on/off volume control which automatically adds bass at low volume settings.
Five position program source selector with complementary indicator lights. High
and low filters for eliminating high frequency hiss and low frequency rumble.
Linear balance control. Speaker selector switch for controlling 2 sets of
speakers, individually or simultaneously. Tape monitor switch for tape playback
or direct tape monitoring while recording. Front panel tape jacks for
headphones and tape-to-tape dubbing. Loudness switch for defeating automatic
bass compensation in loudness control. Full mode switch for monitoring each
channel separately, stereo, stereo reverse, or mono.
Four Channel
Features
Special
individual inputs and outputs for a four channel decoder (may also be used as a
second tape monitor) - controllable with front panel "four channel"
switch. Built-in Dynaquad four channel matrixing circuit - merely add 2
additional speakers for thrilling four channel sound.
