ART Dual Limiter Two-Channel PWM Compressor/Limiter

Dual Limiter - Classic PWM Limiter

The ART Dual Limiter is a 1 RU rack-mountable, two-channel PWM compressor/limiter designed to deliver dynamics processing with low noise and distortion for musicians and audio engineers in recording studios and live stage applications. Its linkable channels allow stereo or dual-mono operation and can be independently bypassed. Each channel features a selectable ratio and adjustable input, output, attack, and release.

XLR and 1/4" balanced inputs and outputs enable proper connectivity with audio interfaces and mixing consoles. Use the 1/4" detector loops to insert outboard gear before each channel's sidechain. Five-segment LEDs provide easy metering of gain reduction. The Dual Limiter's internal power supply eliminates the need for a bulky wall wart power adapter.

Features:

• Two channels of dynamics processing
• PWM (pulse width modulation) gain control circuit
• Low noise and distortion characteristics
• Selectable stereo linking
• XLR and 1/4" balanced inputs and outputs
• Per-channel 1/4" detector loops allow insertion of outboard gear before the sidechain
• Variable input and output levels per channel
• Variable attack and release controls per channel
• Hardwire bypass
• Five-segment gain reduction LED meters
• Internal power supply
• Occupies 1 RU of rack space
