The RC-1570 stereo preamplifier, is a blend of cutting edge digital circuitry with on-board Digital-to-Analog conversation and classic analog stages. Beneath the clean lines and user friendly fascia of the RC-1570 lies highly sophisticated engineering. Both analog and digital sources have been given equal consideration as today’s listener often has several digital sources, but may also enjoy legacy formats like vinyl LPs. The RC-1570 stereo preamplifier is also extremely flexible. Four digital inputs (2 co-ax and 2 optical), plus the rear PC-USB handle digital sources up to 24/192 resolution. The 4 inputs are designed for sources such as TV set-top boxes, flat panel TVs or Blu-ray players for stunning playback. The PC-USB input makes use of audio playback software such as iTunes or Windows Media Player to replay music from your computer digital library. A Bluetooth dongle is provided to be used with the front USB input. A premium Wolfson stereo D/A converter handles critical conversion from digital data to analog. Analog inputs include balanced XLR connectors (perfect for connecting the RCD-1570 via its XLR outputs) in addition to four pair of conventional RCA inputs. A moving magnet phono stage rounds out the source capability. XLR and single ended outputs are provided, as are two 12-volt triggers to control on/off operation of an amplifier and/or other components and RS-232 on a standard DB-9 connector.
