Includes power supply and rack mount bolts/washers.

The Aphex Model 105 is a professional 4-channel logic-assisted noise gate built into a compact 1U rack space. It features four discrete audio channels, an exclusive VCA 1001 core, and a dynamic range exceeding 120dB.

Core Technology & Circuitry

• VCA 1001: Uses an exclusive Aphex Voltage Controlled Attenuator for a clean audio path with virtually zero clicks or pops during fast gating.
• Logic Assisted Detector: Provides stable, accurate triggering no matter how fast your attack time is set.
• Peak Stretch: Dynamically widens the level gap between unwanted background noise and your main audio signal.

Controls & Rear Panel

• Channel Controls: Includes adjustable parameters for threshold, attack, hold, and release, plus switchable attenuation from 6dB to 90dB.
• Operational Levels: Each channel features a rear-panel switch for -10dBV or +4dBu balanced 1/4-inch jack operation.
• Sidechain Access: Includes key trigger inputs on the back with front-panel active indicators.
