LM-2
The LM-2 is an active input module which allows a microphone and a stereo line input to be connected to the Zone Mixer in a remote location. The faceplate has both phonos and a
3.5 mm jack socket for connection of the line input, and provides a convenient access point for the connection of a DJ mixer, laptop, MP3 player or similar. Mic and line inputs have separate level controls. A MIC PRIORITY button activates the Zone Mixer’s priority circuitry; when enabled, a microphone signal (post level control) from the LM-2 will reduce the music level in the zone where it is installed. Changing a rear jumper alters the priority operation so that the mixed mic and line signals from the module cause the mixer’s line input selected to the Zone to be fully muted.
The module also includes the functions of the RSL-6 Remote
Control Plate (see opposite), permitting control of zone
music level and source.
The RL-1 Series is a range of small plates with a single control for locally adjusting the music level in a zone. They connect to one of the mixer’s REMOTE SOURCE + LEVEL ports. See “Connecting an RL-1 Series remote control plate” on page 15 and “RL-1 Series and RSL-6 Series remote control plates – general considerations” on page 22 for more information.

The LM-2 connects to one of the unit’s Facility Ports via screened Cat 5 cable, and the remote inputs are fed to that zone only. The mixer’s Mic inputs remain available. Multiple
LM-2s (in the same zone) may be daisy-chained to provide
mic inputs in more than one position. The LM-2 is available in sizes to suit UK, US and German electrical back boxes; a choice of nishes is also available. See “Connecting an LM-2 remote input module” on page 12 and “LM-2 active input modules – general considerations” on page 21 for more information.
Z4-8MK4 Installation and User Guide v1.26
The RSL-6 Series is a range of plates of the same size as the RL-1s; they connect in a similar way. They allow local music source selection as well as music level control. See “Connecting an RSL-6 Series remote control plate” on page 16 and “RL-1 Series and RSL-6 Series remote control plates – general considerations” on page 22 for more information.
PM Series paging microphones
Cloud PM paging microphones may be connected directly to the Z8MK4 and Z4MK4. Models are available which can page to 4, 8, 12 or 16 zones. Clearly, not all zones on the ‘higher’ models can be addressed with only one zone mixer. See “Paging System connections” on page 13 for more information.
PM1 paging microphone
The Cloud PM1 paging microphone is also compatible with the Z8MK4 and Z4MK4. It is a much simpler unit which addresses only one zone. See “Connecting a PM1 paging mic” on page 14 for more information.
Block Diagram
The simplied block diagram above illustrates the basic signal architecture of the Z8MK4. Only the routing and logic for one zone
output is shown. The architecture of the Z4MK4 is identical, the only difference being the number of zone outputs.

Hardware Considerations
The Z8MK4 and Z4MK4 Zone Mixers are built in 3U-high 19” rack mount enclosures. It is recommended that the Zone Mixer is installed in a 19” rack wherever possible. The units are approx. 160 mm deep, but 250 mm of rack depth should be available to allow for rear connectors and cabling.
The Z8MK4 and Z4MK4 have low power consumption and there are no thermal considerations other than ensuring that the ventilation grilles are not obstructed once the mixer is installed. The ventilation grilles are at the rear (immediately
above the AC input connector); in the bottom panel (behind the AC mains switch), and in the left-hand side panel. Other
equipment may be installed above or below the Z8MK4/Z4MK4 within this constraint.
The choice of location will be dictated by the specics of
the system and building layout. It is recommended that wherever possible, the Z8MK4/Z4MK4 should be mounted in an equipment rack along with as many of the music sources
(CD players, music servers, TV receiver boxes, etc.) and audio power ampliers (driving the zone loudspeakers) as practical.
When deciding the Zone Mixer’s location, bear in mind that access to it will probably be required even if a full complement
of remote controls is being tted as part of the system, as
some adjustments can only be made on the mixer itself.
System Connections
Music Sources
Connect the system’s various music sources to LINE 1 to LINE 6. Line Inputs 1 and 2 are unbalanced, on standard RCA
jacks (phono sockets), while Line Inputs 3 to 6 are balanced,
on 3-pin 3.5 mm-pitch screw-terminal connectors. All six inputs are stereo, with separate L and R connectors. The sensitivity range available should allow most standard items of audio equipment such as computers/tablets, music servers and media receivers, etc., to operate at a satisfactory level.
Unbalanced sources:
Source equipment with stereo unbalanced outputs may be connected directly to Line Inputs 1 or 2, and as long as the source is adjacent to the Zone Mixer, normal phono-phono
(or 3.5 mm jack-to-phono leads) can be used. Always avoid
using pre-made leads of an unnecessary length.
If it is necessary to connect an item of source equipment with a balanced output to Line Inputs 1 or 2, the ideal method is to use a balancing transformer between the source and the unbalanced input. Suitable audio transformers, which should have a ratio of 1:1, are readily available from major
audio component suppliers. The transformer(s) should be
mounted as close to the Zone Mixer as practical, and housed in a screened enclosure if they are not individually screened. The preferred connection method is shown below.
Power Supply
The Z8MK4 and Z4MK4 are tted with a Universal power supply which can operate on mains voltages from 85 to 253 V. An IEC mains cable with a plug appropriate for your country is supplied. The units’ power consumptions are 10.6 W (Z8MK4) and 6.5 W (Z4MK4), with no accessories connected.
Fuses and ratings
The only user-accessible fuse is an AC mains fuse in the IEC connector housing. Only replace a fuse with one of exactly the same type. The fuse rating is 1 A; the type is a T1A, size 20 x 5 mm, with high breaking capacity.
The fuseholder may be accessed by prising the cover below the connector open, using a small screwdriver. The holder has an extra cavity for storing a spare fuse; note that the “active” fuse is that in the inner cavity.

inputs
If transformers are not available, a balanced source may feed an unbalanced input directly as long as care is taken over how the connections are made. A variety of design techniques are in use to implement balanced outputs in audio equipment, and some designs require different wiring protocols to others. Installers are advised to check the manuals with each item for guidance on how the outputs should be connected to an unbalanced input.
