Page 11: Safety Considerations And Information
Safety Considerations and Information The MA80FT amplifier must be earthed. Ensure that the mains power supply provides an effective earth connection using a three-wire termination. Caution – High Voltage Do not touch any part or terminal carrying the hazardous live symbol while power is applied to the unit. -

Page 19: Installation
INSTALLATION Mechanical The compact size and light weight of the MA80FT combined with its high energy efficiency allows it to be installed in almost any location. It can be easily placed in ceiling or wall voids, or fitted to the rear of display screens or loudspeaker cabinets. -
Page 20: Ventilation
Consideration should also be given to ease of access, should the operational configuration or audio levels need adjustment after installation. In free-standing installations, always fit the polyurethane feet supplied, and do not stand any other items on top of the unit. MA80FT Installation and User Guide v1.1... -

SOURCE 2 RIGHT CHANNEL Unless a Cloud remote control plate or module such as the RSL-6 or LM-2 is in use, the two line inputs are summed together internally, though Line input 1 can be configured to have priority over Line input 2, see “Hi-Z input” on page 24. -

Line 1’s input. When this happens, it switches its music source automatically to Line 1. Once the signal at Line 1 stops (e.g., when an announcement finishes), Line 2’s source will smoothly restore to its former level over approx. 3 seconds. MA80FT Installation and User Guide v1.1... -
Page 23: Mic Inputs
Mic inputs The MA80FT has a single microphone channel, enabling it to be used for paging or announcements. By default, the mic channel is independent and is simply mixed with the summed line inputs. The mic channel can be reconfigured so that it operates as a standard Cloud-type paging input, with selectable mic-over-line priority and triggering by either contact closure or automatic signal detection. -
Page 24: Hi-Z Input
The high-voltage input may alternatively be routed internally to the music channel, where it replaces Line Input 2. This means the MA80FT can be fed, for example, with background music from a 25/70/100 V-line system, allowing it to be fully integrated with an existing building system. - Page 25 100 V-line system Note that the 70/100 V input is suitable for use with either 70 V-line or 100 V-line systems. Do not make any connections to the unused high-voltage input (i.e., either 0-25V or 0-70/100V). MA80FT Installation and User Guide v1.1...

Page 28: Output
Lo-Z output The MA80FT can deliver its rated power of 80 W into a 4 ohm load. When using multiple low-impedance loudspeakers (generally 8 ohms) with a single amplifier, series and parallel wiring should be employed to produce a total load impedance of not less than 4 ohms. -
Page 29: Connecting To 25/70/100 V-Line Systems
When driving 25/70/100V-line loudspeaker systems there is a risk of transformer core saturation at high levels and low frequencies, which can produce distortion. To prevent this, the MA80FT’s output stage is provided with a 65 Hz high-pass filter, which is automatically placed in circuit when SETTINGS DIP switch 6 (SPKR OUT: HI-Z/4Ω) is set to HI. -

Page 31: Facility Port
Facility Port The MA80FT amplifier is provided with a FACILITY PORT in the form of a rear panel RJ45 connector . The primary use of the Facility Port is for the connection of an LM-2 or BT-1 remote active module, but it may also be used to connect RL and RSL Series remote control plates, or as a general-purpose auxiliary balanced input (see “Using the Facility Port as an auxiliary input”... -

Cloud RSL-6 Remote Control Plate, which allows remote control of the MA80FT’s music level and selection of Line 1 or Line 2 as the music source. The BT-1 is a Bluetooth remote audio input module which enables compatible portable devices such as laptops, tablets and smartphones to stream audio wirelessly to the module, and thus into the audio system of the area where the module is installed. -
Page 33: Connecting An Rl Or Rsl Series Remote Control Plate
RSL Series (music source select and level), and RL Series (level only). The MA80FT differs from most other Cloud products in that it does not have a dedicated 3-pin “Remote Control” port: RL and RSL Series plates must instead be connected to the Facility Port . -

Page 39: Troubleshooting - Status Led Indications
Troubleshooting – STATUS LED indications The MA80FT is well protected against errors in speaker wiring and other inappropriate operating conditions. The speaker output is monitored for excessively low impedance (i.e., a short circuit) and for the presence of DC. The internal temperature of the amplifier’s power stage is also monitored. -
