Typical System Configuration—Continued

Fig 1 depicts a typical configuration, where the MZA-4.7 is providing audio into four listening zones. Each zone consists of a room with a pair of speakers, and a suitable controller. Additionally a zone may require TV’s or screens. In Fig 1 three such screens are shown in the Lounge, Gym, and Bedroom. Each zone may be lis- tening/watching any of the connected sources: Satellite Receiver, DVD, Video, Digital Music Server, CD Changer, or Tuner.

■Controllers

Each zone has specific control requirements.

• Zone 1 - The Lounge

The ideal control in the lounge environment is from the sofa or lounge suite.

• Zone 2 - The Study

This is a listening environment where remote con- trols are not welcome on the busy desk. The best solution is a wall-mounted keypad. An Integra key- pad displays amplifier power and source selection status. The keypad learns the source equipment IR commands, and relays these to the equipment via the MZA-4.7.

• Zone 3 - The Gym

An Integra keypad are used to provide additional access to the CD changer, and SAT receiver. In addi- tion the Keypads IR receiver is enabled so that changes can be made using a remote while working out.

• Zone 4 - The Bedroom

An Integra keypad is situated by the bedrooms adjoining ensuite and provides control in that envi- ronment. The bedroom control is via the keypad’s IR receiver and a learning remote control.

Source control IR emitters are plugged into the IR out ports.

There are two IR ports which combine both the control- ler inputs (IR1 + IR2). These outputs control sources required in all zones i.e. DVD, VCR, CD and DMS. Each controller interface has an associated IR Out port that routes IR only to that output. In Fig 1 the SAT emitter is plugged into IR out port IR1, which means the zone 1, 3 and 4 controllers may control the SAT source. The Tuner emitter is plugged into IR Out port IR2, so only the zone 2 controller may control the Tuner.

■Source Components

The MZA-4.7 has RCA audio inputs for connecting seven stereo source components and one mono source. The Fig 1 configuration has only six of the possible eight sources populated.

Each zone may select from any of the connected sources. Someone in the lounge may be listening and viewing the DVD source, while another in the study may be listening to music from the Digital Music server.

All four zones may even select the same source, in such circumstances there is a possibility that all four zones may be trying to control that source – this is not always desirable – so a system should be well planned and where appropriate additional source equipment installed.

■Speakers

Speakers in each zone are connected to the MZA-4.7 by “Home-Run” speaker cables.

Each zone has a maximum loading of 6 ohms.

Fig 1 depicts a powered subwoofer in the study. The subwoofer is driven by the zone 2 preamplifier, and is set to track the zone 2 amplifier volume. The subwoofer vol- ume or offset can be adjusted for correct tonal balance. Fig 1 additionally depicts a pair of speakers in the bed- room. These are the associated bedroom ensuite speak- ers and are driven by a low powered slave amplifier. The zone 4 preamplifier has been set to “Independent” mode and connects to the low powered slave amplifier. Independent mode is where the preamplifier volume may be different from the amplifier volume (within a range of 68), it also has independent Standby and Mut- ing.

■Video Outputs

The composite video outputs are suitable for driving ONE composite video display device. To avoid signal degradation, home runs of appropriate video cable should be less than 100 meters.
