[제품 설명]

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 interfacing with broad range of nominal system levels. Unity gain operation must be achievable by setting these controls at the “U” position.

Each of the units channels shall have independent, infinitely variable adjustment of crossover frequency with controls located on the front panel. This control shall provide a total range of 200:1 when used in conjunction with the units 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 system response adjustment to specific site requirements. 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 made in America and covered under a limited full Five Year warranty. The shipping weight shall be ten pounds, with an overall depth of eight inches.

The crossover shall be the Ashly model XR- 4001, manufactured by Ashly Audio Inc. of Rochester, New York. No other unit shall be acceptable unless data submitted from an independent test laboratory verifies that the above specifications are fully met or exceeded.
