Unbalanced voltage input:
High impedance: suitable for a standard
preamplifier or CD player for example. RCA
output.
Input impedance: 10 kohms.
Connecting loudspeakers
There may be voltages
present at the loudspeaker
terminals which may present
an electric shock hazard if
touched. Always ensure the
unit is switched to OFF or
Standby mode when
connecting or disconnecting
loudspeakers.
,
Each amplification module is numbered and
named (15) for your convenience. To ensure
peak performance, and share the load equally
between the power supplies, we recommend
you connect the speakers as designated by
name. For example, connect the Left Front
speaker cable to 'L.Front' on your
MC20/30/50/70. (Refer to the diagram on
following page.)
Each amplification module has two
loudspeaker terminals (11):
• Positive + (red)
• Negative - (black)
To connect the loudspeakers, connect the
positive (red) terminal of the multi-channel
power amplifier to the positive (red) terminal of
the designated loudspeaker. This will ensure
correct phasing of the audio signal. We
recommend only one loudspeaker be
connected to each amplifier module. Ensure
the loudspeaker terminals are securely
tightened, but do not over-tighten to the point
of damaging the connection.
Use only loudspeaker cables with wellinsulated terminals.
DO NOT SHORT-CIRCUIT THE TERMINALS.
20
Connecting loudspeakers
Connecting an audio source
Each amplifier module has two switchselectable inputs with an associated input
socket for connection to the audio source
such as a CD player). The input sockets (8
and 10) and switch (9) are on the rear panel
and the switch must be set to the required
21
input. Make sure the speaker setup is
consistent. For example, make sure the ‘Right
Front’ speaker is connected to the ‘Right
Front’ amplification module that in turn is
connected to the ‘Right Front’ output of the
source.
22
Connecting a processor
Connect either the balanced (8) or
unbalanced (10) inputs on the multi channel
power amplifier to the processor, making sure
the speaker setup is aligned. For example,
connect module 7 (Right Rear) of the amplifier
to the corresponding ‘R.Rear’ output on the
processor. Make sure you set the selector
switch (9) on the rear panel to either balanced
or unbalanced as per you connections.
23

Currently, the only devices monitored by
HRAS are the MC series of multi-channel
power amplifiers.
It is possible to register devices manually (see
page 35), but it is generally easier and quicker
to allow the software to do this automatically.

Communications
The Halcro MC series have can be controlled
and monitored via a personal computer (PC).
A serial and an Ethernet port are available for
this purpose.
Each port has two modes of operation: plain
ASCII and pseudo-binary. In ASCII mode
commands and messages are sent as plain
text. In pseudo-binary mode commands and
messages are encoded.
Setting the IP address
The IP address can be manually setup or
automatically assigned by a DHCP server on
the network, depending on the DHCP state of
the amplifier.
If DCHP is set to ‘never’ an IP address and
netmask must be assigned via the serial port.
If DHCP is set to ‘auto’ and an IP address has
been assigned manually; you must reset the
IP address to 0.0.0.0 then the DHCP sever will
assign a new address at next start up.
If DHCP is set to ‘always’ a new IP address will
be obtained at start up.
If an IP address is set by DHCP the easiest
way to determine the number is to use the
Halcro HRAS software. This will communicate
with any Halcro equipment on the network via
UDP and report the IP addresses found. For
more information on HRAS software please
see page 31.
Ethernet communications
The multi-channel amplifiers can be
connected to an Ethernet network. There are
three modes of communication which
operate on different ports:
• port 60001 is Pseudo-binary on TCP/IP
• port 60002 is ASCII on TCP/IP
• port 60003 is UDP/IP
HyperTerminal can be used to communicate
with a multi-channel power amplifier.
The commands are the same as for the serial
communications.
Serial communications
Almost any terminal program can be used on
a PC to communicate with a multi-channel
power amplifier. Windows provides a tool
called HyperTerminal, which can be used for
this purpose.
The settings for serial communications are:
Speed: 38400 bps
Data bits: 8
Parity: None
Stop bits: 1
Flow control: Hardware
When first connected to the amplifier via the
serial port, communications are in pseudobinary mode.
44
The commands are as follows:
*m=xx set amplifier enable
bitmask to hex value
*m? print current amplifier
enable mask in hex
*p0 power off (standby)
*p1 power on
*s? status query
LF LF LF exit to ASCII mode
The status message is in the form:
*S!:M0xRxxxxxxxPxVxxxxAxxxxxxxTxxxxx
xxCxxxxxxxDxxxxxxxFxxxxxxxHxxxxxxx
where:
*S!: indicates a message sent
from the amplifier as a
result of an error.
*S?: Indicates a message sent
as a response to a request
for status query.
M0x indicates model number,
M01 = MC20, M02 =
MC30, M03 = MC50 and
M04 = MC70.
Rxxxxxxxx indicates serial number of
amplifier
Px indicates power status, 1 =
On, 0 = Standby
Vxxxx indicates the status of the
power supplies in the order
–5V, +12V, +72Va, +72Vb.
0= off, 1 = on
Axxxxxxx indicates which amplifier
modules are active, 0 = not
active, 1 = active
Txxxxxxx indicates the temperature
status amplifier modules, 1
= OK, 0 = Over
temperature
Cxxxxxxx indicates the load status of
amplifier modules, 1 = OK, 0
= Over current
Dxxxxxxx indicates the operational
status of the amplifier
modules, 1 = OK, 0 = Faulty
Fxxxxxxx indicates the operational
status of the fans, 1 = OK 0
= Faulty
Hxxxxxxx indicates the time in
minutes the amplifier has
been in power On mode.
This does not include time
spent in standby.
45
To enter ASCII mode press return three times
to send three line feeds. Once in ASCII mode
you cannot return to pseudo-binary mode
without disconnecting and reconnecting. The
ASCII commands are as follows:
help print list of commands
version print firmware version
information
status print status information
on enter full-power mode
standby enter standby mode
off enter standby mode
serial print amplifier serial number
model print amplifier model

net show active settings
net reload apply new settings
exit disconnect
Valid states for DHCP are: always, never auto.
Once a change to the network settings has
been made, such IP address or DHCP state,
the command ‘net reload’ must be issued for
these changes to take effect.
