5.1. Digital Inputs
5.1.1. I2S input
The Overdrive I2S input is compatible with the Empirical Audio I2S standard. It
can be driven with a Pace-Car or an Off-Ramp. It supports up to 24/192.
5.1.2. S/PDIF coax input
The S/PDIF coax digital input can be driven from any audio device with digital
output conforming to the S/PDIF standard IEC-60958. The input impedance is
75 ohms. It is recommended that stock transports and devices other than that
manufactured by Empirical Audio use a 1.5m minimum 75 ohm digital cable in
order to minimize the jitter caused by reflections. Devices manufactured by
Empirical Audio can use a 1m 75 ohm digital cable length.
5.1.3. USB input
The USB input can be driven with a 5m (16-foot) USB cable from any USB2.0
port on a computer. The USB port supports up to 24/192 sample-rate and uses a
custom software driver for each OS version of Windows or Mac.
