Digital Inputs (OPT, COAX, USB)
The P 5’s built in DAC (Digital to Analog Converter) uses a high resolution 192kHz Burr-Brown
DAC IC. Since the P 5’s DAC is superior to the DAC in most source components. They will
sound better if you connect their digital output to the P 5 instead of using its conventional analog
line output.
Opt (Optical)
The optical input is a high speed Toslink receiver with a 25MHz bandwidth. It accepts these
standard sampling rates: 8kHz, 11.025kHz, 16kHz, 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96
kHz, 176.4kHz and 192kHz. It accepts 16 bit and 24 bit word lengths.
Optical Cable Note: 176.4 kHz and 192 kHz sampling rates will only play reliably with
a very short optical cable. Be careful when handling the optical cable. It has limited
flexibility and it cannot be bent at a sharp angle without impairing its ability to transfer
the digital signal from your source to the P 5.
Coax (Coaxial)
The Coax (also called S/PDIF) input connector is an RCA jack. The Coaxial input accepts
these standard sampling rates: 8kHz, 11.025kHz, 16kHz, 32kHz, 44.1kHz, 48kHz, 88.2kHz,
96kHz, 176kHz & 192kHz. It accepts 16 bit and 24 bit word lengths.
USB
The USB input is used to connect your P 5 to your PC or Mac computer. This allows high
quality playback of any music that is stored on your computer and streaming music services
accessed over the internet. The USB accepts sampling rates of 44.1kHz, 48kHz, 88.2kHz
and 96kHz. It accepts 16 bit and 24 bit word lengths. The P 5 uses the USB 1.1 Audio
standard which allows use of 15’ (5 m) USB cables without any performance penalty.
USB Cable Note: Use a high quality USB cable for the best results. This is particularly
important for cables that are more than 6' (2 m) long. Inexpensive,
long USB cables are often unreliable and could cause drop outs.
Using a Blu-ray or DVD Player's Digital Output
If you use a Blu-ray, DVD player, Cable Box or Satellite Receiver’s digital output with the P 5 you
must go to its setup menu and set the player’s digital audio output to Stereo PCM (2.0). The P 5
accepts only two-channel stereo PCM. It does not accept Dolby, DTS or DSD format signals.
