Learn what the MOON 791 network player / preamplifier adds to an existing hi-fi system and follow a step-by-step process to connect it to your amplifier.
Quick answer
The MOON 791 network player / preamplifier adds streaming, digital-to-analog conversion, and analog preamplifier control to an existing power amplifier or integrated amp. To integrate it, connect its analog outputs to your amplifier’s input, set the 791 as your source, and configure your network.
What the 791 actually adds to your system
The 791 combines three components in one chassis: a network player based on MiND 2, a full DAC, and a high-quality analog preamplifier. This means you can stream music from your network, convert digital signals from other sources, and control volume without adding separate boxes.
The analog regulation M-VOL3 and dual-mono topology are designed to maintain clarity and a quiet background even at low listening levels. This is particularly useful if you listen at night or in a small room where noise floor matters.
When to use the 791 as your preamp
Use the 791 as your system’s preamplifier if you have a power amplifier or an integrated amplifier with a bypass or main-in input. If your integrated amplifier lacks a bypass, you can still connect the 791 to a regular line input, but you’ll be running two volume controls in series—set the integrated amp’s volume to a fixed level and use the 791 for adjustments.
If you already own a high-quality standalone preamp, you might use the 791 as a source only, connecting its fixed outputs to your preamp. The 791’s preamp section is then bypassed, but you still gain streaming and DAC capabilities.
Step-by-step: connect the 791 to your amplifier
- Check your amplifier’s inputs: Identify whether your amplifier has a power-amp input, a main-in, or a bypass input. If it does, you can use the 791 as a full preamp. If not, use a regular line input and set the amplifier’s volume to a moderate fixed level. Using a bypass input avoids double volume control and keeps the signal path clean.
- Connect the analog outputs: Use high-quality RCA or XLR cables (depending on your 791’s outputs and your amplifier’s inputs) to connect the 791’s preamp outputs to your amplifier’s chosen input. Ensure the connection is snug but not over-tightened. Match cable type to the connectors on both units; don’t force a cable into the wrong socket.
- Set the 791 as the active source: On the 791, select the correct input if it has multiple sources, and set the volume to a low level before playing anything. On your amplifier, select the input you used. Always start with the volume low to protect your speakers and your ears.
- Connect to your network: Use an Ethernet cable for the most stable connection, or join your Wi-Fi network via the 791’s setup menu. Install the MiND 2 app on your phone or tablet and follow the pairing instructions. A wired connection reduces dropouts if your Wi-Fi is unreliable.
- Verify playback and adjust settings: Play a familiar track and confirm sound comes from both channels. If you hear distortion, check that the 791’s volume is not too high relative to the amplifier’s input sensitivity. Use the 791’s volume control for normal listening. If using a non-bypass input, set the amplifier’s volume once and leave it; use the 791 for daily adjustments.
