Installation
The Connection Diagram (Figure 1) shows
how all of the different connections on the
back of the ZAM can be used. The diagram
shows the use of Modular Multi-Source
equipment but the ZAM is equally at
home in a single source system.
Because it is such a versatile amplifier
there are several different configuration
levels to choose from and not all of the
amplifiers features may be needed.
Listed below are two of the most common
ways in which the installer might wish to
use the product:
1. As a direct substitute for ALM2
loudspeakers when using passive ceiling
speakers of a different brand
In this instance the ZAM will be connected
to the Hub via the System input from
which it will receive all necessary power,
audio and data connections.
The speakers should be connected in the
usual way using ordinary loudspeaker
cable. In order to control the amplifier
it will be necessary to employ either a
Keypad or single IR receiver (supplied)
and handset.
The ZAM can be easily fitted through the
ceiling cut out and sited in the ceiling
void next to the speakers. It is not even
essential to secure the ZAM in place as it
is small and light enough to sit between
the joists on the plaster board or ceiling
tiles; it gives off very little heat when
operational.
There is also the option in this
configuration to add a Remote Power
supply from a PIM, which will increase the
available audio power output
2. As a Systemline Modular compatible
amplifier for use with traditional floor
standing or bookshelf Hi-fi speakers
For this configuration the ZAM will need
to be in the room near to the speakers.
The power audio and data can again be
provided from the Hub system input with
extra power available from a Local Power
input via a dedicated PSU130.
In this configuration it may be convenient
to add a local source component using
a phono to stereo jack lead (QED J2P
optional) on the line-input socket. If
required, the ZAM can be used as a
control amplifier because the pre-out will
drive most power amplifier inputs. Again
a choice should be made whether to use a
Keypad and handset or IR receiver to send
commands to the amplifier.
The best place to site the amplifier is to fix
it to the wall using the screws provided.
The lettering on the front and rear panels
is optimised for this orientation, however
it is also possible to site the amplifier on a
table top and rubber feet are provided for
this purpose.
Using the ZAM
The ZAM is ready to use straight out
of the box with no need to make any
configuration settings. It will respond to
commands from single and multi-source
Systemline handsets and keypads in
exactly the same way as the ALM2 Active
Ceiling Speaker.
Once powered up and connected into a
system the ZAM will display a red power
LED to indicate standby. The amplifier is
activated by sending either the standby
command from a Systemline Modular
handset or Keypad or a specific source
command from the multi-source versions
of both.
ZAM40 Zone Amplifier
The ZAM 40 amplifier is designed for use with a Systemline Modular Multi-Room Audio Distribution
System only. Specifically it is intended for use where standard active ceiling speakers are not required.
It can be integrated into the system in exactly the same way as the active ceiling speaker but requires
the addition of separate passive speakers. The ZAM can be mounted in the ceiling void or on the wall.
Like the active ceiling speakers the ZAM utilises the latest Class D amplifier technology to deliver the
high fidelity of a class AB amplifier with the low power consumption and space saving features that
result from its 90% efficiency.
