Aerial connectors

The AVR400 is fitted with an AM/FM receiver module and a DAB receiver, depending on the region where it was sold. The type of aerial you need depends on your listening preferences and the local conditions.

Your AVR400 is capable of superb radio reception, but only if it is receiving a good quality transmission signal.

Try the aerials supplied with your unit. If you are in a medium to strong signal area, these should be adequate for good reception. In areas with poor signal strength, you may require a roof or loft mounted aerial.

Contact your local Arcam dealer or aerial installation experts for advice about local reception conditions.

DAB

(where fitted)

In strong signal areas, the DAB ‘T’ wire aerial

supplied can be used with reasonable results. Mount the aerial as high up as possible on a wall.

In the UK the

‘T’‑elements need to be positioned vertically for DAB reception since broadcasts are vertically polarised. In other localities, check with your Arcam dealer or try both horizontal and vertical positions for best reception.

Try each usable wall of the room to see which gives best reception

and use tacks or adhesive tape to secure the aerial in a ‘T’ shape, but note that no tacks should come into contact with the

internal wire of the aerial.

When installed and receiving DAB, check the signal strength by pressing the front panel or remote control’s INFO button until the signal quality indicator is displayed.

In weak signal areas, a high-gain, externally- mounted or roof-mounted aerial is desirable in order to receive the highest number of services.

In Band III transmission areas (such as the UK), use a multi-element Yagi aerial with the elements mounted vertically, as the transmissions are vertically polarised. If you are close to more than one transmitter, use an omnidirectional or folded dipole aerial.

If the DAB services in your area are transmitted on L-band, then ask your dealer for advice for the best aerial to use.

FM

Connecting an aerial

A suitable FM aerial must be connected to

the AVR400 before FM

radio can be received.

In strong signal areas, the wire FM aerial

supplied can be used with

reasonable results.

When installed and

receiving FM radio, check the signal strength by pressing the front panel or remote control’s INFO button until the signal indicator is displayed.

In weak signal areas, or for optimal FM radio reception, a roof- or loft-

mounted aerial is advised as this will give superior reception.

In some areas, cable radio may be available or, in an apartment building, a distributed aerial system may be installed. In either of these cases you should have sockets in your home marked FM or VHF (do not use those marked TV); these should be connected to the FM coaxial connector on the rear of the AVR400.

AM

Connecting an aerial

An AM aerial is required to receive AM/medium wave radio signals, so a simple loop aerial is supplied with the AVR400. Follow the assembly instructions in the diagram below.

Make sure that the aerial is positioned well away from the AVR400 itself, TVs, computers and other sources of RF ‘interference’. Rotate the aerial to discover which position gives the best reception.

3.Connect the lead wires to the AM socket at the rear of the AVR400 (the wires are not polarised). Rotate the aerial’s stand until you obtain the best reception.

2.Push the tab into the open slot in the base of the stand. Press until the tab clicks home.

1.Release the tie-wrap and unwind the twisted lead. Fold the plastic stand forward through the loop frame.
