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. Ashly 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. This model also includes a 200:1 tuning range, output mute switches, and both TRS and XLR connectors. Like other Ashly products, the XR-1001 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.
What does this all means? Simply, this unit separates the highs and lows and delivers the appropriate frequencies (sound) to the amplifiers.
