Key Features:
- In the “fixed” mode, the WA-1B delivers the natural attack & release time of the optical element. In “manual” mode, dial in attack/release controls on the WA-1B front panel. In fixed/man mode, the release time combines settings in fixed and manual mode with the fixed attack (1 msec) mode.
- The dedicated sidechain bus selector offers three positions (Off, Bus 1, Bus 2), allowing you to interconnect and link up to 10 WA-1B compressors in your signal chain.
- The WA-1B is outfitted with a front-mounted meter-adjust control. By having this knob on the front panel, there’s no pause in creativity and no need to unrack gear in the middle of a session when you need to zero out the VU meter.
