Description
MOON 491: Network Preamp for Vinyl Records and Digital Music
As a network player and preamplifier, the MOON 491 handles source selection, digital-to-analog conversion, and volume control before a power amplifier or active speakers. Your vinyl collection remains part of the system just like music from the server or streaming services. A switchable MM/MC phono stage and headphone amplifier are already built in.
What Sets the MOON 491 Apart
- Music selection without switching sources at the rack: MiND 2 provides access to online services, network files, and additional listening zones.
- Conversion and power supply: A dual-mono DAC and MOON Hybrid Power form the technical basis for digital playback.
- Vinyl collection and TV sound: An adjustable MM/MC phono stage and HDMI ARC complement the analog and digital inputs.
- Different system concepts: Regulated RCA and XLR outputs, as well as a fixed-level output, allow for various connection options.
- Operation at the device or from your seat: A color display, app, and CRM-4 remote control are included.
From Your Favorite Album to Your Own Collection: Music on the MOON 491
Today a new release, tomorrow an album you haven't heard in ages from the music server: With the MOON MiND Controller app for iOS and Android, you can access both. Supported services include Qobuz, TIDAL, Deezer, and Spotify. If you prefer to stay in your usual service app, you can use Qobuz Connect, TIDAL Connect, or Spotify Connect.
Roon can also be integrated, and the 491 is Roon Ready. AirPlay and Bluetooth open up additional ways to connect your mobile device to the system; the player connects to the home network via Wi-Fi or Ethernet (LAN).
For stored music, you have the choice between UPnP/DLNA on the network and compatible USB storage connected to the USB-C host connection. With additional MiND-2 devices, playback extends beyond the music room: Even locally connected analog sources can be transmitted to other listening zones.
Digital Playback in the MOON 491
In the DAC, two ESS-9039Q2M converters work together in a dual-mono arrangement with a precision clock. To power the sensitive audio circuits, MOON uses Hybrid Power, a power supply designed for stable, low-noise DC voltage.
MOON 491 and Existing Sources
No separate phono stage is required for vinyl records. The phono input accepts MM and MC cartridges; gain, load impedance, capacitance, and equalization can be adjusted in the menu to match the system. Additional analog sources are connected via line-level RCA or the balanced XLR input.
A CD transport can pass its digital signal optically, coaxially via S/PDIF, or via AES/EBU. For the TV, HDMI ARC handles the audio connection, provided the TV outputs stereo PCM. Which commands the TV remote control can pass through HDMI-CEC can be configured.
Outputs and Headphone Connection of the MOON 491
How the system continues after the preamplifier remains open: The regulated RCA and XLR outputs are suitable for power amplifiers, suitable active speakers, and active subwoofers. If an existing integrated or preamplifier is to control the volume, the RCA fixed-level output serves as the source output.
Prefer listening to music through headphones in the evening? A 6.35 mm stereo jack is located on the front of the device. When headphones are connected, playback through the connected speakers is automatically muted.
Within a compatible MOON system, MOONLink makes joint operation easier, such as switching to standby or adjusting the display brightness.
Operate the MOON 491, Control It from Your Listening Seat
Album covers, volume, and playback information appear on the large color display. The controls on the device are located directly below or beside it; from your seat, you can use the app or the included CRM-4 remote control.
Optionally, the BRM-1 Bluetooth remote control can be paired. It displays the input and volume on its own screen, among other things, and does not need to be pointed at the 491.
The Design of the MOON 491
Glass-bead-blasted aluminum panels define the design of the enclosure.
Suitability and Important Notes for the MOON 491
Who Is the MOON 491 Suitable For?
- Owners of a separate power amplifier or active speakers.
- Those who use vinyl records, streaming, and existing sources in the same stereo system.
- Homes with a local music collection and multiple MiND-2 listening zones.
Important Notes for the MOON 491
- Not all USB storage and file systems are compatible. For larger collections, a DLNA server is recommended.
- A flat, stable surface and sufficient space for ventilation are required.
MOON 491 and MOON 371: Differences in System Concepts
With the MOON 491, the power amplifier and source management can be chosen independently; the MOON 371, on the other hand, drives passive speakers directly, thus eliminating the need for a separate power amplifier. For symmetrically connected power amplifiers, the 491 additionally offers regulated XLR outputs, while for existing amplifiers, it provides an RCA fixed-level output. Its AES/EBU input complements the digital connection types available on the 371.
The 491 also offers more extensive cartridge adjustment: In addition to MM/MC presets, individual load values and equalization curves can be selected, while the 371 uses fixed MM/MC configurations. Although the enclosure width and height are identical, the 491 is shallower. However, its lower power consumption does not account for the additionally required power amplifier.
| Feature | MOON 491 | MOON 371 |
|---|---|---|
| Device Concept | Network player and preamplifier | Network player and integrated amplifier |
| Passive speakers and power amplifier performance | Separate power amplifier required; power depends on the selected power amplifier | Direct connection; 100 W per channel at 8 Ω, 200 W per channel at 4 Ω |
| Regulated preamplifier outputs | RCA and balanced XLR | RCA |
| Separate fixed-level output | RCA, for use as a source with an amplifier | No separate fixed-level output |
| Additional AES/EBU digital input | Available | Not available |
| Phono stage and adjustment | MM/MC presets as well as Advanced: adjustable gain, impedance, capacitance, and RIAA/IEC equalization | Choice between fixed MM and MC presets |
| Power consumption: Idle / Full Power Standby | 16 W / 14 W; without external power amplifier | 30 W / 28 W; including integrated power amplifier |
| Enclosure depth | 35.7 cm | 38.5 cm |
| Shipping weight | 9 kg | 9 kg |
Conclusion
The power amplifier is already selected, and the music selection is to remain open: This is precisely the role of the MOON 491. It complements a separately built stereo system without distributing daily operation across multiple source devices.
