9. INPUT Section

The input section is used to inspect and configure the audio inputs of the device. A warning is displayed

when a digital input is not present but selected as clock master, or routed to an output and is either not

present or not in sync to the clock master. Related input settings, such as AVB stream size or MADI auto

input, can be configured here.

The line level inputs of the M-32 AD Pro II-D accept levels of up to +24 dBu. Each individual channel has

its own line level setting of +13/+19/+24 dBu which can also be adjusted remotely. Additionally, the AD

converters can be globally set to standby (mute).

At single speed sample rates, the converters are configured with short delay 'sharp' IIR filters with

extremely low latencies (5 samples) and flat frequency response over the entire audible range. At higher

sample rates, a short delay 'slow' filter is used to additionally optimize the impulse response. The latency

increases to six samples at quad speed (176.4 kHz, 192 kHz).

In its default state, no routing exists between the analog inputs and the digital outputs. The analog

signals can be routed to two MADI ports and eight AVB streams at the same time.

To adjust the input line level on the device:

1. Open the Analog Input tab in the INPUT section

2. Initially, the cursor will highlight all input channels. To accept this, rotate the encoder to move the

cursor to the current reference level

3. Alternatively, pressing the encoder on the channel strip allows the selection of an individual channel

4. Push the encoder on the current line level, then Rotate the encoder to change the setting and confirm

by pushing the encoder again.

To adjust the input line level on the web remote:

1. Select one or more analog input channels by clicking the corresponding channel strips. The channel

strips turn blue.
