Relay Volume Control Finished Board – 0-300 Step Volume AdjustmentThis Relay Volume Control Board offers precise volume adjustment and excellent left-right channel balance, making it a superior replacement for traditional potentiometers. Designed for audiophiles, it combines simplicity and practicality, perfect for DIY upgrades.
Key Features:1. High-Quality Components
- Takamisawa Signal Relays: Minimal signal loss.
- DALE Blue Resistor (USA): Ensures high channel balance, low error, and accurate sound reproduction.
2. Advanced Volume Control - 360-Degree Encoder Knob: Smooth 0-300 step volume adjustment. Turn right to increase volume, left to decrease.
- Balanced Output: Audio and control circuits are fully isolated, ensuring no signal interference.
3. Multi-Channel Output Control - The 6P socket on the board outputs control signals for 3 or 4-channel input switching (compatible with our 3/4-channel input switch boards).
- Adjustable via SET points: Disconnect SET for 4-channel control; connect SET for 3-channel control.
4. OLED Display - Orange Display: Shows input status (left) and volume level (right).
- 5-Level Brightness Adjustment: Customize display brightness to your preference.
5. Remote Control Functionality - Control volume (up/down), mute, and input switching remotely.
- Volume Ramping: Press and hold for continuous volume adjustment.
6. Remote Learning Function - Learn commands from NEC-encoded remotes (common in audio equipment).
7. Power-On Memory - Remembers the last volume and input settings before shutdown.
8. Independent Volume Adjustment for 4 Inputs - Set different volume levels for each input (e.g., CD at 20, phone at 50) for consistent output levels.
- Option for global volume control, adjusting all inputs simultaneously.
9. Power-On Volume Limiting - Set a maximum volume limit. On power-up, if the last volume exceeds the limit, it automatically adjusts to the set value.
10. Remote Power On/Off - Use an optional relay board to control power for other circuits (e.g., preamp or amplifier).
- Choose between 10A (small devices) or 30A (high-power devices) relay boards.
11. Smooth Transitions - Advanced software algorithms ensure seamless volume changes without popping noises.
12. Balanced Volume Control - Combine two boards for balanced circuit volume adjustment.

Operation Guide:1. Volume Adjustment: Rotate the encoder knob; the 3-digit display shows the volume level.
2. Input Switching: Press the knob to switch inputs; the left digit shows the input status.
3. Mute Function: Long-press the knob until the volume flashes to mute. Repeat to unmute.
4. Brightness Adjustment: Long-press until "L" appears, then rotate to adjust brightness (1-5 levels).
5. Volume Mode: Long-press until "U-" appears, then toggle between "U-4" (individual input control) and "U-A" (global control).
6. Volume Limiting: Long-press to set the maximum volume limit.
7. Remote Learning: Long-press until "8888" appears, then follow prompts to learn remote commands.
8. Disable Remote: Long-press until "ir" appears, then toggle between "ir1" and "ir2" to disable the included remote.
