Sample Rate. Changes the sample rate.
You can set the sample rate to 44.1, 48, 88.2, 96, 176.4, or 192 kHz. A higher
sample rate will increase the fidelity of the recording but will increase the file
size and the amount of system resources necessary to process the audio.
Clock Source. Sets the digital clock source.
From this menu, you can set the clock source for your Quantum
interface: Internal, External S/PDIF, or External ADAT. Please note: Only
ADAT 1 can be used as a clock source input for your Quantum.
4.2 Input Controls
The following controls are available for your Quantum-series interface inputs:
Microphone and Instrument Preamps
The inputs on your Quantum-series interface are auto-sensing. When an XLR cable is
connected, controls for the microphone preamp will be available in UC Surface.
These controls include a fully variable gain control and phantom power as well as
input metering.
Line Inputs
When a ¼-inch TRS cable is connected to the inputs of your Quantum-series
interface, you will be provided with an input sensitivity toggle switch. By default, the
input sensitivity is set to +4 dBu. Most professional line-level devices output at this
level. Consumer line level is usually -10 dBV. For these lower output devices, switch
the input sensitivity to -10 dBV to match your device.
Power User Tip (Quantum users): By default, inputs 1 and 2 are set to line, inputs 3-8
default to mic when nothing is connected.
ADAT Inputs
When a DigiMax DP88 is connected to your Quantum interface’s ADAT Input
and Output, you will be presented with ADAT controls, allowing you to remote
control your DigiMax DP88’s preamps, direct line input, and phantom power.
