• The WA-215 can be installed into a partition wall using the supplied pattress box.
• The WA-215 can be surface mounted if necessary, using the supplied backbox.
• Ensure adequate ventilation and keep away from combustible material or moisture.
• Ensure that the WA-215 is within range of the sending device if using Bluetooth.

Cleaning

• Use a soft cloth with a neutral detergent to clean the housing as required.
• Do not use solvents for cleaning the unit.

Loudspeaker Installation

The WA-215 wall amplifier is available separately or as a WA-215-SET. If supplied as a WA-215-SET, there are 2 ceiling speakers supplied. The speakers may be installed into plasterboard or tiled ceiling with at least 80mm to accommodate the mounting depth of each speaker.
The speakers should be wired to the WA-215 amplifier using a standard twin speaker cable. 10m of suitable cable is supplied with the WA-215-SET and should be cut as required.
Carefully mark out and cut a hole 170mm diameter for each speaker.
Feed the speaker wires from each hole to the WA-215 (passing through the backbox) Connect the + and – wires from the WA-215 speaker outputs to the 8Ω and COM screw terminals and offer the speaker to the hole in the ceiling with the spring clamps on either side of the magnet pressed fully up to fit through the hole. The spring clamps will fold back down to hold the speaker in place. (see opposite)
If the WA-215 is supplied without speakers, ensure that the load to be connected to each speaker output has no lower than 8Ω impedance and has a power handling of 15W max. Do not connect further speakers as this can cause damage to the WA-215  amplifier circuitry.

Backbox installation

The WA-215 is supplied with a single gang 60mm deep backbox and mounting plate for flush mounting or surface mounting to a wall. Install the backbox to the chosen location and knock out any of the pre-punched discs in the sides for cable access as required.
Screw the mounting plate into the front of the backbox and feed power, speaker, trigger, and signal wires through the backbox to the WA-215 and connect to the relative terminals.(see “Connections” on the next page)

Alternatively, the mounting plate can be fitted into a standard 86 x 86mm pattress box top accommodate the WA-215, so long as there is a minimum 47mm mounting depth 953.132UK, 953.137UK User Manual

Connections

Connections to the WA-215 are made using the Euroblock screw terminals at the rear.
These terminals may be unplugged for convenience when inserting the wiring into them.
Ensure all the following speaker, FM aerial, remote play/doorbell, AUX input, and isolated mains wiring is already fed through the wall and through the backbox ready for connection to the WA-215 rear panel.
A line-level input from an external audio source may be connected to the AUX L & R terminals.
These should be fed from the audio source to the WA-215 using a shielded 2-core cable. Connect Left+ and Right+ to the AUX L & R terminals and both Left- and Right- to GND.
A doorbell function is available by connecting a momentary switch across the BELL and GND terminals.
For remote play/pause control, a momentary switch may be connected between the REMOTE PLAY and GND terminals.
A stereo Aux line output can be connected to further equipment via the OUT terminals.
Connect Left+ and Right+ from the OUT L & R terminals and both Left- and Right- to GND.
For better FM reception, an aerial may be connected to the FM ANT terminal.
Connect the outer screen of the aerial cable to the GND terminal.
Lastly, connect right and left speaker wires to the relevant “R-/R+/L+/L-” terminals.
When the above connections are completed, move to the separate 3-terminal block on the top of the rear housing. With the mains isolated, connect 230Vac mains to the separate block of 3 screw terminals. Connect LIVE to “L”, Earth to “GND” and NEUTRAL to “N”
Feed the wiring carefully into the wall cavity to take up any excess, rather than compressing it inside the backbox, which may damage the wire and connections. Push the WA-215 unit firmly onto its mounting plate to fix into the backbox or wall cavity. Keep the mains power isolated (off) until the WA-215 is fully installed into the wall, covering the rear panel wiring. If any function is not operating correctly once installed, isolate the mains power again before removing the WA-215 unit from the wall or backbox.
To remove the WA-215 from the mounting plate, insert a screwdriver in the center of the bottom of the faceplate, lever the faceplate forwards, and carefully prize the edges of the WA215 away from the mounting plate.
Re-check connections and replace the WA-215 before switching the mains power back on.
