Transducer and mid-range assembly rotation
The Platinum In-Wall 3G has the ability to be positioned in a left/right vertical
or horizontal centre channel conguration.
To position the Platinum In-wall 3G in a horizontal centre channel position,
rotate the ‘mid-pod’ that houses the MPD transducer and mid-range assembly.
Follow the instructions below to rotate the transducer and mid-range assembly.

Setting up your system
2-channel system
When arranging a 2-channel system, the listening position and the speakers should form
an equilateral triangle. The speakers should be positioned approximately 1.8 - 3m (6 - 10’)
apart. They should be positioned so that the transducer is at approximate ear height when
you are in your listening position.

Setting up your system
AV positioning
Please refer to the illustration on the right for the ideal angles and positions of each
speaker in your surround system.
If setting up a 5.1 system you should place your surrounds in position (A).
If setting up a 7.1 surround system you should place your side speakers in position (B)
and rear speakers in position (C) to create a full 360° soundstage.
The centre channel should be positioned so that it is pointing at the viewing position
and at approximate ear height.

7.1 = B + C

Setting up your system
Dolby Atmos®
When arranging the overhead channels in a Dolby Atmos®system, we would
recommend using our three-way in-ceiling speakers such as our Platinum
PLIC II speakers. These employ a unique midrange / tweeter module, which
offers a wider dispersion characteristic, and are ideal for Dolby Atmos®duties.
Please see the diagram on the right for ideal positioning of 2 or 4 Dolby Atmos®speaker
setups. Typically these would be in line with the front left and right speakers.

Setting up your system
Connecting speaker cables
The Platinum In-Wall 3G has one set of terminals for single wiring. Single wiring is
achieved by using a single set of cables to the binding posts on the side of the speaker.
Internally the speaker crossover guides the frequencies to the appropriate driver/tweeter
- low frequencies to the bass drivers, mid frequencies to the mid/bass driver and high
frequencies to the transducer.
The binding posts are sprung for ease of use and will accept bare wire only.
Press down on each binding post to reveal the through hole and pass the bare wire
through the hole. Release the binding post and it will automatically clamp the cable in
place. Ensure there are no loose strands of cables to cause a short circuit.
Level adjustment switches
The Platinum In-Wall 3G comes with a pair of switches to adjust the mid and high
frequency levels. These are located on the front of the cabinet at the bottom (when
positioned vertically) and adjustment will either boost or attenuate the mid-range and
tweeter levels by +/-1dB. There are separate switches for each unit, and experimentation
is recommended to achieve the perfect combination for your environment.

Using your speakers
Running-in your speakers
Run your speakers in by playing normal music at low-mid listening levels for
approximately 50-70 hours play time. You may nd the sound will continue to improve
even after the 70 hour mark.
This can be done naturally over time: like a ne wine the performance will improve
with age.
