Operating Manual - XR1001, XR2001, and XR4001 Electronic Crossovers

1.INTRODUCTION

Your ASHLY crossover is the product of an in- tensive research effort which combined a reexamination of traditional crossover theory with practical field use. Over the years, a number of refinements and new models have been added to our crossover series, but the original design goals have remained the same: to produce a cross- over which is sonically accurate, is flexible enough to suit a wide variety of systems, and affords maximum pro- tection for speakers and drivers.

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 un- usual 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 bal- anced inputs, a peak level indicator, a precision regulated power supply, protection against abnormal input or out- put 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.

Due to the similarity of the operating controls on our various models, we have prepared this one manual to cover our complete crossover line. Specific notes on each model will be found in separate application notes. Many owners are unaware of the ease with which you can reconfigure your crossover for nonstandard operation. For example, a 4-way crossover can easily be used as a mono 2-way with tunable subsonic and ultrasonic cutoff filters, and a stereo 3-way can function as a mono 5-way cross- over. No internal modifications are necessary, and audio performance is not compromised. In addition, this manual covers normal setup and operation and offers troubleshoot- ing tips. Please take time to read it before

operating your crossover.

2.UNPACKING

As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to en- sure flawless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing materials , as they were carefully designed to reduce to minimum the possibility of

transportation damage should the unit again require pack- ing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to cover the damages can be initiated.

The right to any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton and packing materials are not avail- able for inspection by the carrier. Save all packing mate- rials until the claim has been settled.

3.AC POWER REQUIREMENTS

Unless otherwise indicated on the back of the unit, all crossovers should be connected to a 3-wire grounded outlet supplying 120 Volts, 50-60 Hz. Some export models are 240 volts, and are labeled accordingly.

This unit will perform normally from 92 to 130 volts AC. A “brownout” condition occurs when avail- able AC power falls low enough to take the unit’s DC power supply out of regulation, increasing noise and low- ering signal headroom. In general, avoid powering your audio system with AC circuits that additionally run large refrigeration compressors, air conditioners, electric heat- ers, lighting systems, etc.

This unit has an internal line fuse. In the un- likely event that the fuse should blow, refer the product to a qualified service technician. Power consumption is 15 watts.

4.SECURITY COVERS

For installations where it is desirable to protect the front panel controls from tampering or accidental misadjustment, use the Ashly security cover, which is available in both single and double rack space sizes. In- stallation is simple and does not require removal of the equipment from your rack. See your Ashly dealer for de- tails.
