to Master, respectively Slave, using the units' set of menus available via the front panel pushbuttons and display. Please
refer to section 4 of this manual for more information on how to set up both units.
3.3.2 Single-channel preamplification board
The single-channel preamplifier board holds the audio path creating the preamplifier itself. It is a monaural path, one channel can
be processed on a single board (Left or Right in stereo configurations, Center, Sub, Left surround or Right surround in multichannel
configurations). The preamplifier board contains the input stage, the volume control circuitry and the output buffer. It also holds
the DC offset cancellation circuitry, allowing to reduce clicks to near zero levels.
It features selectable analog inputs on three different types of connectors: balanced XLR, single-ended RCA and BNC. The inputs can
be configured for high-impedance or 600 Ohms load (for balanced inputs) and 300 Ohms (for single-ended inputs). It allows an
optimal signal transmission when connected to upstream pieces of equipment with 50 or 75 Ohm output impedance. The 600/300
Ohms load is engaged on a single input basis, it is not a global setting for all the inputs.
Connect your sources to the inputs of the single-channel preamplifier board. The name of the inputs displayed on the front panel
screen can be customized for better clarity (please refer to section 4 of this manual for more information on how to change the
default input names). If more inputs are needed, the True Monaural Extended configuration is the way forward. Please refer to
section 1.1.1 of this manual for more information.
The outputs are driven by a discrete buffer, capable of supplying ample current to drive even the most demanding amplifier's input
stages or long molulation cables all the way to distant monoblocs. The multiple outputs are in parallel, allowing to connect multiple
amplifiers in a multi-amplification system.
