Operation Instruction Manual

Rxti2 loop reciever

Technical Description

If the level of background hum is excessive then
it may be necessary to boost the output power of
the loop amplifier to overcome this background
noise.

The RXti 2 may also be used in non hard of
hearing situations such as multilingual transla­tion systems or museum talk through systems,
and stage managers talk back systems.

The RXti has been designed to allow installers,
and the non hard of hearing to test and assess
the quality and audibility of the loop system.

In order to improve the quality of the receiver we
have implemented a dual inductor system which
helps reduce the background noise from com­puter monitors and fluorescent tubes. The audio
response from the receiver is flat from 100Hz to
13KHz, to allow an installer to assess the back­ground noise in a room with no loop amplifier
running. If the room is to be used for the hard of
hearing and there is a low level ‘mains hum’
present this will not normally effect the hard of
hearing user, as their hearing aids will have a
50Hz filter to remove the hum.

Batteries

To fit the batteries, remove the rear battery com­partment lid, and insert 2 AAA battery cells.
Alkaline or long life types are recommended for
continuous use, but the unit will function with
ordinary zinc carbon cells. If the unit is not to be
used for a long period of time, remove the batter­ies to prevent leakage and or damage to the unit.

Headphones

The RXti 2 can be used with a wide range of
headphones designed for use with ‘walkman’
style radio/cassette recorders. These can be ‘in
ear’ types, or normal lightweight types, however
when purchasing the headphones please ensure
that the impedance stated for the units is no
greater than 32 ohms. This is normally printed on
the side of the box, or in the specification sheet.
The RXti 2 will not function properly with 600
ohm hi-fi type headphones.

Soft Start

In order to prevent large clicks or pops when
switching the unit on, we have introduced a ‘soft
start’ to the receiver. This means that when you
first turn it on the volume will be very quiet. After
a few seconds the soft start will cut out and the
unit will function at full volume. Care should be
taken not to turn the volume control up too far
initially, as the receivers volume may be too high
when the soft start function finishes.

Caution
The audio output from RXti 2 can
exceed 100mW into 8 ohms, and this
may cause hearing damage with long
term exposure. Therefore Care should
be taken not to use excessive volume
when testing loop systems.
