Loop 4 way 5mm euroblock screw terminal (supplied) for each
Connectors output, for twisted pair or star-quad congured feed cables
DCOutput 2 way 3.5mm euroblock screw terminal Re-settable, fuse
protected 12V 0.1A. Controllable to reect amplier status
(network models only) note powering an external device via
DC out or USB may reduce power headroom available for
the loop.

balanced output
AUDIOSYSTEM
Frequency 80Hz to 6.5kHz
Response
Distortion THD+N <0.3% 1kHz sine at full current
Automatic The AGC is optimised for speech. Dynamic range >36dB
GainControl
MetalLoss Corrects system frequency response issues due to metal
Correction structures in a building. Gain constant at 1kHz, adjustable
gain slope from 0 to 4dB per octave in 0.25dB increments.
Custom 2 slope MLC allows different slopes and
transition frequency to be set via the menu (network
models only).
This does not compensate for signal loss from metal
structures which can be signicant.
PhaseShift User selectable (network models only) at 0° or 90°
between outputs

Standards compliance
These products are designed to form part of a system that can meet all of the requirements of the international loop performance standard IEC60118-4, and the
relevant parts of IEC TR 63079. To fully meet requirements of these standards, correct design, installation, commissioning and maintenance are required.
All specication data has been compiled in accordance with IEC62489-1, the international performance reporting standard for audio frequency induction loop
equipment. Specication data should only be compared with data compliant to this standard.
This product is CE and RCM marked to all relevant safety and EMC standards, and is MET Labs approved for sale in North America.
Note: dual channel drivers can be used to power two
perimeter loops each up to this size, with the same
input audio signal provided to both.
Perimeter loops can be used in small rooms with
moderate metal loss, but if possible should be tested
on site to conrm performance.
The Perimeter loop systems shown here are modelled
as single-turn loops using 2.5mm² single wire and
installed at height where required (essential in larger
rooms)
The MultiLoop loss gures shown are based on
maximum 2m wide loop segments installed at
oor-level using 3.0mm² Flat Copper Tape with a
suitable gap to wall. Larger sizes will result in higher
loss which may signicantly impact coverage area.
Moderate metal loss
†
example used:
Concrete with moderate reinforcement (~5dB)
High metal loss
‡
example used:
Proled Steel Deck and Metal System Floor (~9dB)
All calculations are based on square rooms.
Please note coverage will be greater in long, narrow
areas.
These gures are a guideline only and shouldn't be
used to specify a system. For an accurate simulation
