CS1 Endpoint Network Streamer
Plug and Play
A compact, minimalist design, the NAD CS1 has a pair of line-level analogue RCA outputs for connection to a stereo receiver, integrated amp, preamplifier, or a pair of powered speakers. Alternatively, you can use the CS1’s optical or coaxial output to send digital audio to an AV receiver, external DAC, or a pair of powered speakers with digital input, at up to 24-bit/192kHz resolution.
You can connect the CS1 to your home network via Wi-Fi or hardwire its LAN Ethernet port to your network router or an access point, or use Bluetooth® to pair the CS1 with your mobile device.
 
Stream Your Way
You don’t have to install special apps to play music through the NAD CS1 Endpoint Network Streamer. Using Bluetooth, you can stream audio from any app on your smartphone, tablet, or computer.
You’ll get even better sound via Wi-Fi or Ethernet. The CS1 supports AirPlay 2, so you can stream CD-resolution audio from any app on an iPhone, iPad, or Mac, or from an iTunes library on a Windows PC.
