Ashly XR-4001 Quick start guide

XR-4001
The unit shall be a stereo four-way 24dB per
octave electronic crossover in a two rack space
metal chassis. The unit shall have separate front
panel input level controls on all channels for inter-
facing with broad range of nominal system levels.
Unity gain operation must be achievable by setting
these controls at the “U” position. Each of the unit’s
channels shall have independent, infinitely variable
adjustment of crossover frequency with controls
located on the front panel. This control shall pro-
vide a total range of 200:1 when used in conjunc-
tion with the unit’s adjacent Range switch. There
shall be a Response control calibrated in decibels
on each channel to adjust the damping of that filter
at the crossover point, thus allowing variable sys-
tem response adjustment to specific site require-
ments. The unit shall have separate clip indicators
to monitor all internal amplifiers for any possible
overload conditions. Each channel of the crossover
unit shall have a separate output level control and
mute switch located on the front panel. There shall
be separate inputs and outputs for each channel
on 1/4” TRS phone jacks and XLR connectors, any
of which may be used balanced or unbalanced.
In addition, there shall also be an independent
mono summed output labeled MONO LOW OUT (on
a separate 1/4” TRS jack and an XLR jack). The
crossover must be covered under a limited full Five
Year warranty. The shipping weight shall be sixteen
pounds, with an overall depth of eight inches. The
crossover shall be the Ashly model XR-4001. No
other unit shall be acceptable unless data submitted
from an independent test laboratory verifies that
the above specifications are fully met or exceeded.
