A practical, step-by-step guide to setting up the MOON 491 network player preamplifier for streaming, including network, input, and amplifier connections.

Quick Answer

Connect the MOON 491 to your network via Ethernet, then use its preamplifier outputs to feed a power amplifier or powered speakers. Select the correct digital input for your source and verify streaming playback before critical listening.

Why the 491 Simplifies a Streaming System

The 491 Netzwerkplayer / Vorverstärker combines a network player and preamplifier in one chassis. That means you can stream music and control volume without a separate preamp, reducing box count and cable clutter. For many listeners, this integrated approach is the main reason to choose the 491 over a standalone network player.

However, because the 491 handles both streaming and preamplification, its setup involves two logical stages: getting it on the network and integrating it with your amplifier. Skipping either stage can lead to silence or degraded sound.

What You Need Before You Start

Gather an Ethernet cable (or Wi-Fi credentials if you prefer wireless), a power amplifier or powered speakers, and the appropriate interconnects (balanced XLR or single-ended RCA). Also have your streaming service login details and the MOON app or a compatible control point ready.

The 491 is available in a Standard configuration; check your unit for the specific input/output options installed. If a particular digital input is not present, you will need to use an alternative connection or an external DAC.

Step-by-Step Streaming Setup

Connect to your network: Use an Ethernet cable from your router to the 491's network port for the most stable connection. If you must use Wi-Fi, follow the menu prompts to join your network. Common mistake: assuming the unit is streaming-ready without checking the network indicator. Confirm the network status light is solid or as described in the manual before proceeding.
Power on and select the network input: Turn on the 491 and use the front panel or remote to select the network player input. Wait for the unit to obtain an IP address (this may take a moment). Checkpoint: the display should show a network connection or ready status. If the display shows no network, recheck the cable or Wi-Fi password.
Connect to your amplifier or powered speakers: Using balanced XLR or single-ended RCA cables, connect the 491's preamplifier outputs to your power amplifier or powered speakers. Match left and right channels carefully. Common mistake: plugging into fixed-level outputs instead of variable preamp outputs, which bypasses volume control. Verify you are using the preamplifier outputs, not a record-out or fixed output.
Set volume to a low level and play a test track: Start with the 491's volume at a low setting, then play a familiar track from your streaming service or local library. Gradually raise volume. Checkpoint: you should hear sound from both channels; if not, check input selection and cable seating. If one channel is silent, swap cables or speakers to isolate the issue.
Configure streaming services and app control: Open your preferred control app (e.g., MOON app or a third-party UPnP/DLNA controller) and log in to your streaming accounts. Select the 491 as the output device. Common mistake: forgetting to enable the network player in the app's device list. Ensure the app shows the 491 as an available renderer.
Check digital inputs for other sources: If you plan to connect a TV, CD transport, or external DAC, use the available digital inputs on the 491. Select each input and confirm signal lock. Checkpoint: some inputs may require enabling in the menu. Test each input you intend to use before final cable management.
