Safety instructions Warning – High Voltage – Risk of Death! Opening the Audiobeam while it is connected to the mains is likely to result in a lifethreatening electric shock! There are no user serviceable parts inside – if the Audiobeam should become defective, any repairs must be carried out by an official Sennheiser Service Partner. If the unit is opened in breach of this instruction, the warranty becomes null and void.

Mounting Audiobeam Correct mounting conditions 왘 When mounting Audiobeam, make sure that: y the ultrasonic sound wave can travel undisturbed for at least 1 m before it strikes the first surface. y a minimum distance of 10 cm is maintained between Audiobeam and adjacent objects so that any heat generated can dissipate. Make sure that the air vents at the top and rear of the unit are not covered or blocked! y a minimum distance of 1 meter is maintained between Audiobeam and combustible materials.
왘 Use an XLR-3 cable to connect the audio source (e.g. CD or DVD player, mixing console, receiver of a wireless microphone) to the audio input INPUT 쐋. Audiobeam automatically emits ultrasound as soon as an audio signal (see “Specifications”‘ on page 6) is present at the audio input INPUT 쐋. 왘 Use the mains cable 쐆 to connect Audiobeam to the mains. Secure the mains cable with the steel clamp 쐎. 왘 The LED operation indicator 쐃 lights up green, indicating that Audiobeam is ready for operation (standby).
