MOON 750 D Digital-to-Analog Converter / CD Transport

Rear Panel Connections

Figure 2: MOON 750D Rear panel

The rear panel will look similar to Figure 2 (above). On the left side are two pairs of analog audio outputs, labeled “Right” and “Left”, each with a single-ended RCA and balanced XLR connector. Don’t hesitate to use good quality interconnect cable when making the connection between the MOON 750D and your preamplifier or integrated amplifier. We strongly recommend that you use the balanced XLR connectors on your 750D to maximize its level of performance.

The middle section contains two rows of connectors for digital audio. The top row has four (4) digital inputs labeled “D1” (AES/EBU), “D2” (S/PDIF), “D3” (TosLink) and “D4” (USB). The bottom row has two (2) digital outputs – one each AES/EBU and S/PDIF. When using either of the S/PDIF digital connections, you should always use a 75Ω digital audio cable terminated with RCA connectors. If you decide to use the AES/EBU digital output, use a dedicated AES/EBU 110Ω digital audio cable terminated with XLR connectors.

The right side of the rear panel has various connectors for external communications. The MOON 750D is equipped with full- function bi-directional RS-232 port control and status for custom integration or automation. Immediately to the right of the RS-232 port are two (2) “SimLink” connectors labeled “in” and “out” on 1/8” mini jacks. Please refer to the next section entitled SimLink for more details.

Your MOON 750D DAC / CD Transport has a 1/8” mini jack input for use with aftermarket infrared remote control receivers. The “IR in” connector is located immediately to the right of the “SimLink” connectors.

Directly below these communications interfaces, there are a pair of 4-pin XLR connectors labeled “External Power Supply” “Input 1” and “Input 2”. These are reserved for future use when an external power supply will be made available for the

MOON 750D.

Finally on the right side is the “AC Power” section with a main power switch (“0”=off, “1”=on) and IEC receptacle for the included AC power cord.

All rear panel connectors have been chosen because they provide the best possible connections for your unit. A poor contact will degrade the signal substantially, and plugs and sockets should all look clean and free of dirt and corrosion. The easiest way to clean them is to remove the cables from their sockets and push them back in again. This procedure requires that your DAC / CD Transport and the rest of your components be completely turned off. Not heeding this warning may result in serious damage to your equipment. Special contact cleaning fluids and enhancers should not be used, as they deposit a difficult to remove residue which degrades the performance of your components.
