IP7-MZC Zone Controller System
Overview
The IP7-MZC (Multi Zone Controller) is an IP Endpoint with the ability for the caller to enable or
disable microphone and speaker feeds in multiple full-duplex audio Zones during a session.
Up to 48 Zones are supported using the MZC using cascaded ZX4L Zone expander boards.
Each ZX4L adds 4 Zones, with control of 4 microphones and 4 speaker connections
Zone control within the IP7-MZC is made though a SIP connection or with a custom TalkMaster
FOCUS PC application. Please refer to the TalkMaster FOCUS SDK for information on software
support.
Additional features include:
 ANALOG TELEPHONE SUPPORT - An RJ-11 jack for connection of a standard analog


telephone to the IP7-MZC to communicate over the IP connection. Picking up the analog
handset can optionally initiate a call and/or temporarily shut down the audio on the Zone
Expansion Zones. Once connected, the handset provides full duplex communication with the
caller
DVR RECORDING OUTPUTS: A monitor audio access terminal that outputs an aggregate
feed of all active audio zones to a DVR. Multiple monitor access points are also available on each
ZX4L expander to allow every zone to have a unique DVR channel recording
INTEGRATED 10/100 PASS THRU PORT: A high speed 10/100 LAN port is available to cascade
IP connections to downstream devices, including additional Digital Acoustics IP endpoints or cameras

INSTALLER TESTPOINTS: Onboard mini-speaker and microphones are included to allow service
technicians to quickly diagnose, debug and test audio paths with local access.
NOTE: This Hardware Guide refers to System Installer interconnects and wiring conventions.
Refer to the IP7-MZC System User’s Guide for operation and general product usage.

Troubleshooting
Eliminating Audio Hum
The IP7-MZC uses a “floated” ground. If the speakers attached to the Zone Extenders have
“hum”, then connect the IP7-MZC’s Earth Ground Screw Hole or any one of the GND
connectors to an earth ground.
Reset to Factory Defaults
The IP Address information and all Intercom options can be reset to factory defaults by the
following procedure:
● Unplug the Power
● Press and hold the “Vol +” and “Vol -“ buttons
● Power the unit
● Wait till the unit plays a 3 tone beep (about 8-10 seconds)
● Release the “Vol +” and “Vol -“ buttons
● Refer to the software manuals for instructions on configuring the IP address information
Viewing tech support info via the USB port
If requested by Digital Acoustics Support, a USB cable can be attached to the IP7-M-ICC to
capture additional information.
● Attach a USB cable to the USB-B
connector on the IP7-MZC and a PC
running Windows®
● If an “Install Hardware” prompt is
displayed, tje USB Virtual Com port
driver can be found in the main
directory of the Software install
● Open the Windows Device Manager to
determine the virtual Serial port that
has been assigned
● Use a terminal emulation program
(such as TeraTerm) to access the
‘virtual’ serial port. Assign the settings
to 115kbs, 8,N,1, no flow control and ANSI Terminal
● Press the Enter key to refresh the display
● If the IP7 is restarted:
○ Disconnect the Com port in the Terminal Emulation program
○ Unplug/Replug the USB cable to re-enumerate the Com port
○ Reconnect the Com port in the Terminal Emulation program
○ Press the Enter key to refresh the display

Setting Volume Levels
The IP7-MZC’s Volume Level is automatically set and the Vol+ and Vol- buttons are disabled in
firmware. Set the volume of the individual zones using the zone’s Speaker and Mic volume
controls on the zone expansion board.

ZX4L - Four Zone Expansion Board
ZX4L Overview
Up to twelve ZX4Ls can be daisy chained to an IP7-MZC. Each ZX4L has four:
● Microphone connections
● Microphone Volume Control
● Speaker Connections
● Speaker Volume Control
● DVR Output pins
The ZX4L is designed to work with 2-wire or 3-wire 12V powered Microphones and speakers
connected to an amplifier or amplified speakers. The speaker connections can also drive an 8
Ohm speaker at 1 watt.
