Output Channels

Two sections provide signal on the AT bus as Dante transmitter channels (see figure 13,

always available to Dante compatible devices on the same network.
Unless renamed, the five pre-processor outputs (
PRE‑OUT‑01 to PRE‑OUT‑05). The AXP 50 C AT output lines (

Both pre-processor and line outputs (Dante transmitters) can be connected to any Dante
device receiver.

Input Channels

There are five (5) mono line input channels. Level controls and processing blocks described
in the following sections are identical for each of the five inputs.

Bypass — Processors are bypassed by default. Signal flow passes through the block
without processing, regardless of the processor settings. Remove bypass to allow the
signal processing according to the parameter settings of the block.
A red mark is in the lower left of the block (shown in the High Pass processor block
below) to indicate a processing block is inserted, but is bypassed.

AEC Reference
Gain (GAIN) — Mono input gain control with a range from -18 to +80 dB includes
a mute button. Step resolution is 0.1 dB. A polarity switch (+ or -) is provided. Gain
control and mute are both pre-meter. The input is selectable between the analog rear
panel inputs and a digital AT bus input.
Filter (FILT) — Up to five filters can be inserted in any combination of High Pass, Low
Pass, Bass & Treble shelving (tone), or Parametric EQ.
Acoustic Echo Cancellation (AEC) — One acoustic echo canceller processor for
each mic/line input . The reference can be selected for each AEC block by routing the
reference using Dante Controller.
Dynamics (DYN) — Two per input channel. Dynamics processors vary the dynamic
level (the range of loudest to softest signals) of the input signal.
Gain (GAIN) — One post-processing gain control per channel with a range of -100 dB
to +12 dB. The step resolution is 0.1 dB.
