M4 fEATURES
M4 Multi-Zone Audio Amplifier/Controller
The M4 is a four-zone, six-source Audio Amplifier/Controller. It serves as the
“brains” of the entire keypad system. The M4 provides audio switching for
six sources and 30W/channel audio power amplifiers for four zones. It also
has connection termination facilities for the controlled whole house system.
DooRBELL/STATUS In 1 & 2 JACKS
These 3.5mm mini phone trigger inputs work in
conjunction with the PHONE PAGE IN jack. When
triggered, the phone inputs can be turned on as
programmed by proficient Editor. If audio paging is
not required, these 1 & 2 jacks may also be pogrammed
as STATUS inputs for power management of source or
zone components. They accept input levels of 3V to 30V
AC or DC for the trigger ON condition. The voltage level
must drop below 1V AC or DC for the OFF condition.
IR oUT
This 3.5mm mini jack, one for each zone, provides dedicated Zone IR
output initiated from the respective zone inputs. They may control
specific zone components when you want to prevent the control of it
from the other zones.
EXpAnSIon poRTS
RJ45 jacks provide for connection
of specialized RS485 controlled
products and for looping to
additional M4 controllers for zone
expansion capability.
RS-232 DATA I/o
Communication port.
phonE pAGE In JACK
This jack provides input porting for audio feeds from
door mikes or other forms of phone or doorbell
paging. The jack is programmable by proficient
Editor, to turn on as events, when triggered by the
DOORBELL/STATUS IN Jack.
ConTACT CLoSURE
Provides a single pole dry relay
contact to activate any device that
can be controlled or triggered by a
switch closure. The closure can be
programmed within proficient Editor
to be activated by keypad presses,
Command Library IR, or within macros
for Momentary, Toggle and Open/
Close Paired operations. Spring-loaded
terminals accept wire sizes from 28 to 14
AWG. Internal relay contacts are rated at
2A/30V AC or DC.
ConTRoL poRT & fIRMWARE UpGRADE SWITCh
3.5mm 4-circuit mini phone jack allows several control functions. All keypad
programming is accomplished via this port using proficient Editor in conjunction
with the mating Transfer Cable. It also accommodates factory firmware updates
in conjunction with the fIRMWARE UpGRADE off/on Switch. Be sure to leave
this switch in the off position at all times, except, as instructed within proficient
Editor, when you are doing a firmware update. Such updates ensure that you can
always have the latest functionality improvements in the field. Another function of
this port is that you can control installed system components with bi-directional
data via touch panels or computers using RS232 protocol.
CoMMon IR oUTpUT & hI/Lo SWITCh
3.5mm mini phone jack provides a common IR output derived from all of
the zone IR inputs and from keypad initiated IR commands derived from
the internal IR library. High or low IR power output is set by means of the
hI/Lo switch. Set it to the Lo setting when driving standard low power
emitters (i.e, Proficient IR single flasher). Set it to the hI position when
driving a high power emitter (i.e, a blaster) for teaching IR commands into
learning remotes. Caution: The hI position will damage or destroy low
power emitters!
CoMMon STATUS oUT poRT
This 3.5mm mini phone jack will go high (+12V DC)
when any zone is turned ON and will go LOW (under 1V
DC) when the last zone is turned OFF. The max. output
of this jack is 100 mA at 9.5V DC.
IR oUT JACKS
These 3.5mm mini phone jacks, one for each source, provide
dedicated IR output to specific source components. When a
source is selected on a keypad, IR function commands are
routed directly to that source. This prevents cross-control
interference between two or more sources that have
identical IR commands.
IR Loop JACKS
These six 3.5mm mini phone jacks, one for each source, are
provided exclusively for zone expansion capability when
using two or more M4 controllers. They permit the
source IR signals from the added zones to be carried to
the source component emitters.
L & R AUDIo In & Loop JACKS
These RCA jacks – four for each source – provide audio
signal inputs and buffered loop outputs, for each
source. The buffered outputs can be used to drive local
components or loop the signals to the additional zone
inputs of other M4 controllers when using them for source
expansion.
IEC TYpE AC
Mains receptacle and fuse mates with included AC
power cord. Also houses the rear panel replaceable AC
mains fuse (T5AL 250V for 120V, and T2.5AL 250V for
230V/240V)
L & R pRE-oUT JACKS
These RCA jacks provide line level
audio outputs for driving external
power amplifiers for additional rooms
within zones, where needed.
VC-nVC SWITCh
The audio output from the PRE-OUT jacks can
either be controlled by the internal volume
control of the M4 (VC position) or be a fixed
line level output in the no volume control
(nVC position). In either case, the tone control
remains available for room “EQ” settings.
KEYpAD ZonE InpUTS
These RJ45 terminals allow for easy
connection of the inter-room wiring
from keypads in the various rooms.
Normally this is accomplished using
CAT5 cable with home-run lengths of
up to 1000'.
L & R SpEAKERS TERMInALS
These 4-circuit plugable screw-down
terminals accept wire sizes from 14 to
28 AWG. They allow quick connection of
the internal amplifiers to stereo pairs of
speakers in the various zone rooms.
