OPTIONS & ACCESSORIES
CAUTION: Modifications must be performed by qualified service professionals. AC power must be
disconnected, and the top panel must be removed before performing any of the following modifications to
the D60EQ.
IN
OUT
FILTER
High-Pass Filter
A
jumper strap labelled ‘FILTER’ on the amplifie
r
circuit board enables or disables an
18dB/octave 180Hz high-pass filter. When the
strap is in the "IN" (up) position, the filter is
enabled. When the strap is in the "OUT" (down)
position, the filter is disabled. To avoid high
magnetization currents which cause the
amplifier to current limit and distort the output
signal when low frequencies are present, the
high pass filter must
be strapped "IN" when
using the autoformer (8 ohm, 70V, 100V)
outputs. This strap is set "IN" when the unit is
shipped from the factory.
Rack Mounting
Rack mounting brackets are provided with the
D60EQ. To install these brackets, the top cove
r
of the unit must first be removed. The brackets
are then attached to the top cover using the
hardware supplied. The top cover is then
reattached.
