Multi-Zone, Multi-Source Switching

The M-401e amplier has four separate
ampliers, providing 4 independent zones
with integrated control. There are 6
input sources comprising the following:

• Sources 1 – 4 are either Analog Stereo,
or Coax Digital Audio (PCM) Digital Coax
has priority if both are connected.

• Sources 5 - 6 are either Coax (PCM) or
Optical Digital Audio (TOSLINK) Only
one connection is permitted to each
source.

• Sources 1 -6 have a programmable
delay: up to 600ms - 5ms steps.

eAudioCast

Four separate ampliers independent
yet integrated control. Multiple remote
sources may be assigned, originating from a
connected eSeries ampliers and streamers.

Amplier Physical Stacking for
Zone Expansion

Additional zones may be added by
physically linking ampliers in a stack
through the Digital Coax connections.
Use sources 1-6 Digital Coax outputs for
connection to the Digital Coax inputs
of additional Autonomic amplier(s).

As an alternative to physically
linking ampliers together, eSeries
ampliers support adding zones over
Ethernet via Autonomic’s proprietary
eAudioCast technology.

Pre-ampliers and Outputs
Each zone has bass, treble, balance and
loudness control. These are accessed
from the front panel or Mirage Web
Interface. A feature called “Maximum
Volume limiting”, is useful for protecting
connected speakers. It may be applied to
both amplier and preamplier outputs.

Amplier Power, Protection,
and Clipping Indicators

55 Watts into 8 ohm loads, and 75 Watts into
4 ohm loads with < 1% THD. The ampliers
are protected against output shorts, and
have algorithms that prevent hard clipping
when the zone ampliers are overdriven.

Thermal Control
There are two progressive
levels of thermal control:

• The amplifier volume is reduced 20dB.

• The amplifiers are shutdown until the
temperature reduces below the first
level.

Care should be taken to ensure
adequate ventilation. See "Important
Safety Instructions" on page 2.

IR Emitter Ports
There are 8 Buffered IR emitter Ports.
Ports 1 – 6 have IR routing, and are intended
to control specic input source components.

Ethernet and IR Control

The M-401e amplier may be controlled
and monitored via Ethernet. An M-401e
amplier may receive IR directly from
the front panel receiver. There are zone
specic IR commands and also a set of
global IR commands. The commands are:

• ON

• OFF

• Standby (toggling)

• Mute

• Volume Up

• Volume Down

• Source Selects

• Discrete Audio Source Selects

• On with Source Specific commands

Features

Thank you for purchasing an M- 401e Mirage Multi-Zone Amplier. Please read this manual thoroughly before making
connections and plugging in the device. Following the instructions in this manual will enable you to obtain optimum
performance and listening enjoyment from your new Multi-Zone Amplier. Please retain this manual for future reference.

Amplier Zone ON Status – "Amp-On"

Each zone has AMP-ON status:
12VDC OUT on the rear panel
connector: (1, 2, 3, 4, 5, 6, 7, 8).

Discrete Audio Selection
Audio selection may be independent. There
are IR Discrete control commands available.

Zone Linking
A zone may be programmed to be linked
with other zones. Zone linking ties the source
selection together. Optionally, it may also be
congured to tie the zone group’s volume and
power. In your specic listening area(s) it may
be advantageous to have different volume
control but the same source, or the same
volume with separate power control. Zone
linking is setup via the amplier’s web interface.

96 Zones
There are 96 zones of possible control. On
an M-401e amplier each zone must be
different, however in a multiple amplier
stack, same zone ampliers are possible
(they simply mimic every parameter).

Power Failure Restoration

After an AC power outage the M-401e
amplier restores its settings to the
ore-interrupted state. All internal
settings are stored in non-volatile
memory, except the clock that runs for
at least 48 hours on stored power.

Restore Defaults

The M-401e amplier may be set to
the default settings. Restoring defaults
clears all memory and resets the zone
allocations to zones 1 – 4. It will also reset
any custom zone and source names to
default (Zone 1 and S1, for example).

Firmware Upgradable
The M-401e amplier may be updated with
the latest operational rmware. See

www.Autonomic-Controls.com for support.

Typical System Conguration (Continued)

Fig. 1 depicts a typical conguration where
the M-401e amplier is providing audio
into six of the possible eight listening zones.
Only three of the zones are depicted.

Each zone consists of a room with
a pair of speakers and a suitable
controller. Each zone may be listening
on any of the connected sources:

• Mirage Media Server

• Satellite Receiver

• Tuner

• CD Player

Controllers
Each zone has a specic control
requirement. Choose controllers
that best suit the application.

Zone 1 – The Gym: Speakers & KP-6 Keypad

Zone 2 – The Study: Speakers &

KP-iOS Keypad

Zone 3 – The Lounge: Speakers & Tablets

1. The KP-6 Keypad may be plugged into
any of the four controller ports.

2. Source control IR emitters are plugged
into the IR ports. There are ten IR ports:
IR1 - IR8, and IR9 & IR10.

3. IR 1 – 6 route source specific IR signals
from connected controllers, while IR9 &
IR10 output the common IR or the sum
of all received IR signals.

4. These ports may be used for source
equipment that is common to all zones.

When controlling a stand alone M-401e
using an iPad or other web tablet, the
M-401e must be connected to a wi-
enabled ethernet router and the web tablet
browser must be directed to the M-401e’s
IP Address. The M-401e’s web application
also provides source control functionality.

Speakers
Speakers in each zone are connected to the
amplier by "Home Run" speaker cables.

Source Equipment
The M-401e amplier has eight stereo
RCA audio inputs for connecting
to source equipment. These input
channels feature coax digital inputs.

If a signal is present on the digital input,
it takes precedence over the analog
input. There are four additional Digital
only input channels featuring both coax
and Optical inputs. Any source can be
listened to in any zone, simultaneously.

All eight zones may select the same
source, in such circumstances there
is a possibility that all four zones may
be trying to control that source (not
always desirable) so a system should be
well planned and where appropriate
additional source equipment installed.

Mirage Media Server
When pairing your M-401e amplier with
a Mirage Media Server, be sure to use the
Mirage Media Server’s web conguration
Sources page and follow the pairing process
there. This will ensure full control via the
Mirage iOS and Android applications.

Multiple Ampli er (Continued)

In large installations where multiple M-401e
ampli ers are required, Ethernet conveys
ampli er control, and link to other Media
sources if connected to the Home network
Router or Switch. Ensure all ampli ers
using same the amp ID in the stack.

The source equipment audio inputs must
be plugged into the  rst ampli er where
they are buffered and sent to the next
ampli er in the stack. The maximum
recommended expansion is 24 units.

Zone

Ampli ers are encoded with up to 96 zones.
The zone byte is used for checking if the
command is applicable to the device receiving
the command and if so, for optionally selecting
a sub-device, e.g. a bank or part of a device.
All Zones are addressed using FF. The lower 5
bits of the zone byte represent the zone 0 – 31.

Selection:

• 00000 bin = 00 (hex) = zone 0

• 00001 bin = 01 (hex) = zone 1

• 01010 bin = 0A (hex) = zone 10

• 11111 bin = 1F (hex) = zone 31

Examples:

Addressing a zone 10 ampli er:
Binary 000 -01010 or 0A hex
Send ASCII "0A"

Addressing all Zone amp & preampli ers:
FF hex Send ASCII "FF"

* Fig 2 shows a stack of M-401e with Source

connections to  rst ampli er where they are
converted to Digital audio, buffered and sent
to the next ampli er in the stack. Use good
quality Coax Digital Shielded RCA cables for
the interconnection, cables should be no
more than 3 meters or 10 feet. The maximum
recommended expansion is twelve units. This
chaining of Ethernet is an option but a direct
connection to the router is the best option.

Notes

• When a command is sent to an amplifier
it will first be transmitted on the control
bus and then returned to the PC (Home
Automation System). If an error occurs an
error will be returned instead of the origi­nal command. The PC (Home Automation
System) needs to ignore its command
when it is returned.

• A Standby ON command implies that the
amplifier is not muted, if the amplifier
was previously Off, a mute command
must follow the Standby command if it is
muted.

• Not all Command and Data commands
are covered in this document.

• The expected reply for the "Send all
Parameters" command (09) is >144 bytes.
All command fields listed in this document
are contained in the reply. The reply also
contains advanced commands not listed
in this document. The home Automation
or PC’s buffer should be large enough to
receive and process the 144-byte reply.

a. Zone 2 links to Zone 3.

b. Since Zone 2 is no longer linked to

Zone 1, Zone 1 will no longer be
linked to Zone 2.

c. Since Zone 3 is no longer linked to

zone 4, Zone 4 will no longer be
linked to Zone 3.

Example strings:

• 010A01: Standby ON command for Zone
