quality 75 Ohm cable for connections to this input.
TOSLINK INPUT
Standard stereo optical input con-
nector for use with consumer devices. Use a stan-
dard TOSLINK optical cable for connections to this
input.
USB INPUT
The stereo USB input for connection
to a host computer. Use a USB 2 (high speed) type
A -to- type B mini cable (included with your m920).
The type A connector is to be plugged in to the HOST
PC and the type B mini connector is to be used with
the m920 input. Due to the very high speed opera-
tion of this interface we recommend a 6ft (1.8 meter)
maximum length for this cable.
Output Connections
STEREO HEADPHONE OUTPUTS
Headphone outputs
are provided via two ¼” TRS (Tip, Ring, Sleeve) jacks.
These outputs are wired in parallel. Connection to
headphones should be made using standard ¼” TRS
stereo connectors.
UNBALANCED LINE OUTPUTS
A stereo pair of unbal-
anced line level outputs are provided via two RCA
jacks. These outputs should be connected to pow-
ered speakers, a preamplifier, or power amplifiers
using standard unbalanced RCA cables.
BALANCED LINE OUTPUTS
A stereo pair of balanced
line level outputs are provided via two ¼” TRS jacks.
These outputs should be connected to powered
speakers, a preamplifier, or power amplifiers using
standard balanced cables. Connection to an unbal-
anced input is also possible. See diagrams below for
proper termination.

Selecting an Input Source
The m920 allows for selection from a variety of
analog and digital input sources. The rotary input
selector switch is used to choose the input source for
both the headphone amplifier and line outputs.
ANALOG INPUTS
The m920 provides both balanced and unbalanced
stereo inputs. To select either of these analog inputs,
rotate the input selector to the desired input. When
an analog input is selected, the m920’s internal DAC
is turned off.
DIGITAL INPUTS
The m920 provides the following digital input
sources: AES3, S/PDIF, TOSLINK and USB. The AES3
and S/PDIF inputs support PCM audio data with
sample rates from 44.1kHz to 192kHz / 24 bit as well
as DSD64 via DoP. The TOSLINK input supports PCM
audio data with sample rates 44.1kHz to 96kHz /
24bit. The USB input supports PCM audio data with
sample rates from 44.1kHz to 384kHz / 32bit in addi-
tion to DSD64 and DSD128 via DOP.
