Facilities
A. Balanced Input
These removable barrier-block con-
nectors (Figure 1.1) make it quick and
easy to attach an input cable with just
three screws. Once the cable is at-
tached, the connector can be quickly
unplugged and, if desired, moved to
a different amplifier.
B. Input Attenuators
Each channel has a calibrated at-
tenuator (Figure 1.1) for accurate
level adjustment. They have 21
detented positions which “click” into
place for ease of use.
C. Subsonic/Bass Switch
A 4-position slide switch for each
channel (Figure 1.2) controls the sub-
sonic/bass filter. This filter is an 18 dB/
octave Butterworth high-pass filter
which can be selected to attenuate
frequencies below 50 Hz, 100 Hz or
300 Hz. It can also be switched off
(FLAT). The switch positions are la-
belled on the circuit board between
the two switches.
D. Horn Equalization Jumper
A jumper is provided for each chan-
nel (Figure 1.2) to enable/disable the
constant-directivity horn equalization.
The jumper for channel 1 (EQ1) is
shown in the ON position while the
channel 2 jumper (EQ2) is shown in
the OFF position. This equalization
circuit is a 6 dB/octave shelving net-
work with a 3 dB rise at 3.2 kHz and
a peak boost of 12.5 dB at 24 kHz.
