Page 7: Front Panel
RNDAC Front-Panel Features Line Out The LINE OUT switch toggles the RNDAC’s rear-panel BALANCED XLR and UNBALANCED RCA line outputs ON or OFF. Gain The GAIN switch toggles between LO and HI gain output for the headphone amplifier to allow the user to better opti- mize their listening setup for the variance in headphone impedance and efficiency between manufacturers. - Page 8 RNDAC Rear-Panel Features XLR Balanced Output The stereo XLR line outputs on the RNDAC are balanced by a pair of custom-wound Rupert Neve Designs transformers, achieving very low distortion while still maintaining the musical, harmonic character for which Rupert Neve is known.
- Page 9 Optical S/PDIF Input The Optical S/PDIF digital input is the second of three digital inputs available on the RNDAC rear-panel. Similar to the Coaxial S/PDIF connection, the Optical connection supports PCM playback up to 192 kHz at 24 bit resolution. The Opti- cal S/PDIF connection is a common alternative found on consumer products such as home entertainment systems and televisions.

RNDAC USB Audio Setup RNDAC Initial USB Connection for Windows The first time the RNDAC is plugged into your Windows PC, you will need to install the necessary drivers to properly enable the RNDAC features. 1. Visit fidelice.com and download the RNDAC Windows driver installer listed on the RNDAC product page. 2. - Page 11 USB Playback Sample Rate Configuration It is important to understand that some media players (such as Tidal and JRiver Media Center) output the correct USB control transfer data to notify the RNDAC to change sample rate based on the source file. However, some media players do not output this data.
- Page 12 4. Navigate to the “Advanced” tab. The “Advanced” menu allows the user to manually configure the sample rate. Select a Sample Rate from the drop-down list and then click “OK. ” Playback may be momentarily interrupted. Sample Rate Configuration (Mac) 1.

Page 13: Dsd Playback
DSD Playback The RNDAC is capable of PCM and DSD playback. PCM (Pulse-Code-Modulation) is by far the most common form of digitally encoded music, however, DSD (Direct-Stream-Digital) is enjoying increased attention from the hi-fi community. Both formats approach audio encoding with different methodologies, and each format has its supporters. It was im- portant that we built in the capability for high-quality PCM and DSD playback within the RNDAC, ultimately allowing the user to decide which format they prefer. -
Page 14: Micro-Usb Firmware Update
Micro-USB Firmwate Update In the event that the RNDAC needs to have its firmware updated, follow this procedure: 1. Start with the RNDAC powered OFF. 2.
