JBL ASC24: The Ultimate 2x4-Channel Crossover and Signal Processor for Immersive Audio
May only be bought as part of a complete system
Get ready to elevate your audio experience with the JBL ASC24! This amazing device provides two analog channels of two-way signal processing for Array Series loudspeakers, delivering outstanding sonic quality like never before. Here's why you need it:
- • Exceptional Signal Processing: With 24dB per octave Linkwitz-Riley type crossover filters, phase compensation, equalization, and limiting for each output, the ASC24 ensures a smooth amplitude response and maximum safe dynamic range.
- • Low Noise Performance: Using low noise components in the active signal path, this processor guarantees quiet operation for any application.
- • User-Friendly Controls: The front panel features level trim controls and channel mutes for quick and easy adjustment.
The ASC24 is designed to meet the highest standards of audio quality. It has a very low noise floor, a frequency response of 30 Hz to 20 kHz, and a 30Hz high-pass filter to protect against infrasonic damage. The mid-filter type limiting circuitry reduces band spreading and produces a smoother response around the crossover point during limiting. Plus, the limiter is placed in a side-chain to the audio signal, removing it from the direct audio circuit during lower operational levels.
