Operator Manual – XR Series Crossovers
XR Crossovers
All Ashly crossovers are based upon the same powerful state-variable filter circuit, which
guarantees that two adjacent frequency band outputs always remain in phase. Our crossovers
offer a number of useful and unusual features, including continuous tuning, a response
control, and a unique output stage, which maintains low noise at any level setting. These
models also include a 200:1 tuning range, output mute switches, and both TRS and XLR
connectors.
Like other Ashly products, your crossover features low noise and distortion, active balanced
inputs, a peak level indicator, a precision regulated power supply, protection against
abnormal input or output conditions, and rugged mechanical construction. Conservative
design and an unusually thorough procedure for quality control have earned Ashly a
reputation for dependability in the recording, sound reinforcement, and broadcast fields.
Connectors & Cables
Your crossover is provided with two different connector types, wired in parallel. 1/4 inch
stereo phone jacks and three pin XLR type connectors will allow interfacing to most
Inputs
Inputs are 20KΩ active balanced, or 10KΩ unbalanced. The inputs of all Ashly crossovers
are in phase with the outputs.
Outputs
The outputs are low impedance (200Ω typical) pseudo-balanced using either connector.
Pseudo-balanced lines have an equivalent line impedance on both (+) and (-) lines,
allowing for long cable runs without compromising common mode rejection of unwanted
noise. For maximum headroom, terminate outputs into loads of 600Ω or greater.
Each model has an additional output labeled MONO LOW OUT. This output represents
the sum of low frequency outputs of both channels, for driving mono sub-woofers in a
stereo system, reducing the number of power amps needed.
professional audio products, with pin 2 hot
(+) and pin 3 (-). The inputs and outputs can
be used balanced or unbalanced. We
recommend balanced between components in
your system, as this minimizes ground-loop
or induced hum and noise.
If either inputs or outputs are used
unbalanced, the signal is on the (+)
connection and the (-) connection must be
tied to ground. A mono phone plug used as
an unbalanced connection will automatically
ground the ring of the jack which is the (-)
connection. When using a stereo plug or
XLR connector for unbalanced input or
output connections, the signal (-) MUST be
tied to ground, or loss of signal level may
result.
