! CAUTION !

YOU SHOUL D PAY ATTENTION TO THE

FOLLLOW ING SAFETY INSTRUCTIONS!

Before setting receivers with rechargeable batteries into operation:

As soon as the rechargeable batteries are inserted in the receivers,

these have to be charged immediately and completely in the

designated SIR C 50 Charging Tray (equipped with Original

beyerdynamic power supply).

Remember: Receivers not changing about 2 or 3 month will result in total discharge. This will cause the destruction of the rechargeable batteries! Therefore total discharged or defective rechargeable batteries will not be longer charged and have to be exchanged. In such a case you only may insert a new set of rechargeable batteries.

We recommend charging the rechargeable batteries every month for approx. 8 hours.

SIR 320 Infrared Multi-channel Receiver

Congratulations on buying the SIR 320 infrared receiver from beyerdynamic! You have invested in reliably conference equipment.

The SIR 320 multi-channel receiver uses the same standards and protocols, which govern all other beyerdynamic infrared transmission systems; this allows operation with other manufactures equipment operating to the same standards. The built-in PLL- (Phase-locked-loop) synthesiser guarantees a high sensitivity as well as good reception.

The new generation of the SIR receivers allows use in direct sunlight, e.g. outside or in places where normal infrared-reception would nearly be impossible due to high light intensity, as experienced at press conferences, on stages, etc. Together with other system components the receiver enables wireless audio transmission.

Carrying clip

There are different ways to “wear” the receiver. The built-in clip allows secure fastening to your shirt or jacket pocket. The clip is not intended using at a belt; this could obscure the lens from the IR signal. Another way is to use the lanyard wearing the receiver around your neck.

Lanyard

The lanyard should pass through both cut-out positions in the carrying clip on the rear of the receiver,

so allowing the clip lying flush to the body of the receiver. In the event of the lanyard being pulled, the carrying clip will release from the receiver housing, this is a designed safety function. The clip’s spring is secured to the clip to prevent loss. If the clip becomes detached it is easily pushed back into place.

Battery cover

… for covering the battery tray. To remove the battery cover the cover screw must be released. The screw is retained in the battery cover and cannot be lost. (Further hints see batteries / rechargeable batteries)

Operation

Starting the receiver

To start the receiver, just press one of the buttons on the navigation pad. The receiver will now display for a short time the firmware version number and then the last selected channel number. The back light of the display will high light for approx. 3 sec. and then switch automatically off to low light to conserve battery power.

Channel selection is via the navigation pad, press “CH ” (to decrease) or “CH ” (to increase). The display shows the selected channel. During the channel selection the audio signal will be muted.

If the buttons are held down when pressed, you can scroll through the channels more quickly.

The display shows the selected channel. When switched off the last selected channel will be stored and the receiver will default to that channel when switched on again.

Channel display

In case of using Shift Mode with a 32-channel receiver, the channel display can switch up to channel 38; however the IR- transmission is supported up

to channel 31. This means that the maximum number of channels that can be used in Shift mode will be 25 (OR+24). Shift mode is a channel offset by a factor of 7 and is selected when interference is experienced with switched energy saving lamps. In case of interference the disturbances are audible up to channel 5 or 6. The interference comes from the first, second, and third harmonic of the lighting system. Adjustment to Shift mode – if required - will be made by the installing company or from an authorised technician.

SIR 320 SIR Infrared System

Volume control / memory function

The volume control is adjusted by “VOL” and “VOL”. During volume adjustment a dot will appear in the top left hand corner of the display to differentiate between volume and channel selection (without dot).

The minimum volume is displayed as “˙00”; maximum volume is displayed as “˙15” . The factory default setting is “˙01”. After use the receiver keeps its last settings. When used again the receiver defaults to these settings. This applies not only to the volume but also to the channel selection. When the volume settings are “˙00” or higher than “˙08” the receiver automatically reverts to the factory default setting of, “˙01” after switch-off. This allows the next user to initially hear the audio signal and to protect the users hearing during switch-on.

The volume should not be at the maximum value (“˙15 ” ) over a long period as this may affect or damage your hearing.

The receiver has an automatic gain control, which protects it from strong signals within a short

distance of the IR radiator panel. A too wide distance between the IR radiator and receiver will result in background noise. An optimised IR radiator installation guarantees a good distribution of the IRsignal, resulting in reception without background noise.

Auto Switch-off function

The following will cause the receiver to switch off automatically:

• after approx. 15sec., when no headphone is connected

• after approx. 60sec., when no infrared signal is received

• directly, when you put it out of the charging tray

Disposable / rechargeable batteries

The receiver was designed to meet the demands of different power supplies. It is equipped with charging contacts and charging regulators are integrated. This gives the advantage to use the receiver with disposable or rechargeable batteries (NiMH – types).

Disposable batteries Type: VARTA Electric Power V8003 Size: LR03, AAA Number: 3 pcs.

Rechargeable batteries Type: SANYO HR-4U Size and number as before.

Attention! Do not use disposable and rechargeable batteries within the same receiver! Otherwise you will invalidate the warranty and damage the receiver itself.

Attention! – Polarity

During insertion of new disposable/rechargeable batteries take care of the correct polarity. Wrongly inserted batteries will leak and damage the equipment.

Charging of the receivers

Take care that you recharge receivers fitted with rechargeable batteries only in combination with the charging tray. Receivers with disposable batteries must not be recharged! Attempts to do so will invalidate the warranty and damage the receiver. If the battery tray is empty you should only put in the receiver in the charging trays when no power supply is connected. The receiver can be damaged!

Battery status (Battery voltage) The battery status can be checked within the Service-mode (SE). Exchange exhausted batteries as soon as possible; exhausted batteries should not be left in the receiver!

Min./Max. Battery voltage for disposable batteries: 3.3V – 4.5V Min./Max. Battery voltage for rechargeable batteries: 3.9V – 4.2V

Changing of batteries

When changing the batteries the receiver may stop reacting. In this case please carry out a hardware reset. (See paragraph Operation > Hardware reset)

Important!

Please remember: Exhausted batteries should not be thrown into the domestic waste! Handle the batteries as hazardous waste and dispose it in accordance with the instructions to product recycling!
