DETAILED FEATURES
Eight Fully Featured Preamplifier Channels:
Precision Gain Control: 0–55 dB continuous gain range utilizing high-quality Polyshine and Alps Alpine potentiometers.
Variable High-Pass Filter: 10Hz – 250Hz sweep range with a steep 24dB/octave slope for precise low-end cleanup.
48V Phantom Power: Independent relay-switched phantom power per channel for condenser mics and active DI boxes.
Polarity Invert (Phase): Relay-switched polarity flip per channel.
-20dB Input Pad: Relay-switched attenuation for high-output microphones and hot Line signals.
Short Signal Path Topology: Relay-controlled switching keeps audio traces minimal and isolated from front-panel switch noise.
Real-Time LED Metering: Dual-LED level indicators (Signal / Peak) per channel for accurate input gain staging.
Audio-Grade Components: Built with audio-grade Nichicon capacitors, precision resistors, and heavy-duty pots.
