Overview The IO3 (input/output) Relay Board (the “IO3”) is a 1.7 inch x 2.5 inch circuit board that can be interfaced with the LDR3x Preamp Controller Board (versions 1 or 2) to enable switching between up to 3 audio input signals. In addition to its primary switching function, the IO3 also serves as an overall interface…
The encoder module is a rotary encoder with integral push button mounted on a small PCB with a 4-pin header and a 6-8 inch 4-pin cable . It comes fully assembled and ready to use. Use the cable to connect directly to any V25, V3 or V4 controller board, or to the OLED display adapter board.
The encoder module is normally included as part of the OLED display assembly which you can purchase here, but we also offer it as a stand-alone item in can you need a replacement for any reason.
Since inception, all Tortuga Audio preamp controllers and other preamp products have utilized a rotary encoder with integral push button as a means for manually controlling the preamp device. While limited in control functionality as compared to using an infrared remote control, the encoder has typically provided a means to control volume, power on/off, mute/unmute, channel balance, and even select between audio input sources.
