POSITIONING THE UNIT

Always place the tuner on a level, firm surface.

SETTING UP THE TUNER

AM STEP SWITCH
The AM tuning ‘step size’ needs to be set according to your location. This is done using the switch on the rear panel: set it to 10kHz if you are in North America, or 9kHz anywhere else. This switch also ensures correct reproduction of FM broadcasts for your location.
AM AERIAL
An AM aerial is required to receive AM/Medium Wave radio signals. An external AM loop aerial is supplied as an accessory. This should be
and the other to Ground 8. It does not matter which way round
9
this aerial is fitted. Rotate the aerial to discover which position gives the best reception.
In areas of weak reception or when the receiver is used inside a steel framed building (such as an apartment building) you can use a wire between 3 and 5 metres long to strengthen reception. Mount this high up outside the building, if possible, and connect one end of this wire
to the AM antenna input 9 as well as the loop aerial supplied. DO NOT DISCONNECT THE LOOP AERIAL.

FM AERIAL
For optimal FM radio reception a roof or loft mounted aerial is advised. For your own safety it is recommended that a roof top aerial is fitted by an experienced contractor. Your Arcam dealer should be able to put you in contact with an aerial installer. A contractor will be able to tune your aerial to the nearest FM transmitter. In an apartment building an aerial system may already be installed. If this is the case you should have sockets in your home marked FM or VHF (do not use those marked TV).
The ‘T’ shaped wire aerial (dipole design) supplied should give reasonably good reception. Mount this aerial as high up as possible on a wall with the elements positioned horizontally. Try each usable wall of the room to see which gives best reception. Use tacks or adhesive tape to secure the aerial in a T-shape. The tacks should not come into contact with the internal wire of the aerial.
Whether you decide to get an aerial professionally installed or opt to use the supplied aerial it should be connected to the FM Antenna
input 7 on the rear of the unit. For use in North America, use an F-type antenna connector; for Europe
and other areas, use a female Belling Lee-type coaxial connector.

CONNECTING TO OTHER EQUIPMENT

INTERCONNECT CABLES
Interconnecting cables are not supplied with this tuner. We recommend high quality cables as inferior quality cables will degrade the sound quality of your system. Please contact your Arcam dealer for details of suitable cables. Arcam do not recommend any particular type or brand of interconnect cable.

CONNECTING YOUR TUNER TO YOUR AMPLIFIER

AUDIO OUTPUTS
Two pairs of identical outputs are provided. Connect one set to your amplifier’s tuner input or any other line-level
input using suitable high quality interconnect cables. Ensure that the left and right audio outputs from the tuner are connected to the same left and right inputs on your amplifier.
The second set of audio outputs can be used to connect to a second amplifier set up for ‘multiroom’ use, or routed to a tape recorder for ‘off air’ recording.

CUSTOM INSTALLATION FEATURES

The T31 has a number of useful features that make it ideal for a custom installation, where the tuner is fully integrated with a specialist control system or operated by a programmable remote control.
REMOTE CONTROL INPUT
Use of this socket disables the front panel IR eye.
TRIGGER INPUT
The trigger socket allows the tuner to be remotely switched in and out of standby. The primary front panel POWER switch must be in, ‘on’, for this mode.
Apply a +12V DC voltage for ‘on’, the power indicator glows green; 0V for ‘standby’, the power indicator glows red.
Note that use of this socket requires a 12V signal before the tuner can be switched fully on.

CONNECTING TO A POWER SUPPLY

WRONG PLUG?
Check that the plug supplied with the unit fits your supply and that your mains supply voltage agrees with the voltage setting switch (115V
or 230V) indicated on the rear panel of the unit 2. If your mains supply voltage is different, switch the voltage selector
across using a small screwdriver.
MAINS LEAD
PLUGGING IN
Push the plug (IEC line socket) of the power cable supplied with the unit into the POWER INLET socket 1 in the back of the unit. Make
sure it is pushed in firmly. Put the plug on the other end of the cable into your power supply
socket and switch the socket on.
The T31 responds to a set of Philips RC-5 codes in addition to those available on the supplied handset, which is kept simple for ease of use.
