LOWPASS ON/OFF
Pushing this button "IN" engages the Lowpass filter. Pushing this button
"OUT" will bypass the filter.
LOWPASS FREQUENCY
Turning this control sets the Lowpass crossover point from 50Hz (fully
counterclockwise) to 5kHz (fully clockwise).
HIGHPASS ON/OFF
Pushing this button "IN" engages the Highpass filter. Pushing this button
"OUT" will bypass the filter.
HIGHPASS FREQUENCY
Turning this control sets the Highpass crossover point from 15Hz (fully
counterclockwise) to 1.5kHz (fully clockwise).
Note: By engaging both Highpass and Lowpass filters and setting the desired
crossover points, a Bandpass filter can be created:
AUXILIARY CROSSOVER
Signal can be parallel routed from the INPUTS (X-OVER INPUT SELECT
button set to the "IN" position) or be directly sent to this crossover via the
AUX. X-OVER INPUT RCA jacks(X-OVER INPUT SELECT button set to
the "OUT" position). This configuration allows the AUX crossover to be used
with a separate stereo amplifier not equipped with its own on-board crossover
for the ultimate in system flexibility.
D7 CROSSOVER FREQUENCIES
Diamond Audio D7401 features fully variable crossovers. The frequency
control knobs (located in the tray on the top of the amplifier) when rotated all
the way to the left are labeled 50Hz Lowpass and 15Hz Highpass. When
rotated all the way to the right are labeled 5kHz Lowpass and 1.5kHz
Highpass.
To make basic setting of the crossover frequencies a little easier, we've
come up with the following rotational diagram:

FREQUENCY
Notice that the outer most circle of numbers (1:00, 2:00, etc.) represent
numbers as they appear on the face of a clock. The number underneath each
"hour" designation on the simulated clock face is the approximate crossover
frequency at that position.
BRIDGING
The D7401 is a mono-block (one channel) amplifier. There is no need to
"bridge" the outputs. The two sets of outputs are paralleled inside the amp for
installation convenience. This allows for a 4 Ohm load to be wired to each set
of outputs and the amp will see a 2 Ohm load. This also allows for a 2 Ohm
load to be wired to just one set of inputs (either one).
Note: It is important that a 2 Ohm minimum total speaker impedance load is
observed! If an impedance load of less than 2 Ohms is used, you will
eventually damage your amplifier and void your warranty.
