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.

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

additional M4 controllers for zone expansion capability.

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,

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

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.

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.

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.
