OVERVIEW
Introduction
The MA40F and MA40T are very compact mono amplifiers designed for integration
into audio and AV systems where de-centralised installation is advantageous. They
are intended as "install-and-forget" components, and are small enough to be fitted
into wall or ceiling voids or in any convenient location adjacent to projectors, flat
screen displays or loudspeakers. A simple set of controls and configuration options
makes them easy to integrate into any audio system.They are highly suitable for use
with in-store digital signage, gallery and museum exhibits and fixed or mobile tour
guide systems.
The MA40F can deliver 40W (mono) into a 4 ohm load, while the physically larger
MA40T includes an output transformer, enabling it to drive 100 V, 70 V or 25 V
line loudspeaker systems. In all other respects, the two models are identical. There
are two unbalanced inputs for line level signals (typically music sources) and a
balanced mic input for paging/announcement use. An alternative mic input allows
the amplifier to be fed with paging/announcements from a 70/ IOOVline loudspeaker
system. Front panel preset-type controls are provided for music level, microphone
levels and music EQ. There are also various preset adjustments and configuration
DIP switches on the rear panel, and jumpers mounted internally on the main PCB.
A remote input module or remote level control can be wired to the amplifier's
Facility Port, which can also be used as an additional line input.
Applicable Models
This Installation Guide describes the installation and operation of the following
modeis:
• Cloud MA40F
• Cloud MA40T 40W mono amplifier for 4 ohm loudspeakers
40 W mono amplifier for 100/70125V line loudspeaker
systems
The two models differ in physical size, the MA40T being larger in order to
accommodate the internal line output transformer.Apart from the inclusion of this
transformer, the two models are essentially identical for the practical purposes of
installation and operation. Unless specifically stated otherwise, the information in
this Guide may be taken to apply to either model.
