B460IRR40P V1.0 Azden IRR-40P ‒ User & Installation Guide
Azden IRR-40P Soundfield
Auto power-off
The Swift
TX
monitors the sound level and if the level drops below approx 76dB SPL for more
than ten minutes, then the unit will switch off automatically to preserve the battery.
The Swift
TX
is normally used on channel A. However
it can be easily changed to channel B as follows:
Open the battery compartment.
Inside, just above the battery, you will be able to see
a small switch labelled ‘A channel B’.
Use the end of a paperclip to slide the channel
switch.
Always replace the battery compartment cover
afterwards.
Channel change
The IRR-40P unit has two mic receiving channels 1 & 2. The Swift
TX
A/B channel change
switch is in the battery compartment. (A = 1, B = 2)
Pendant, beltpack or handheld transmitters can be used on either channel.
Microphone
Dual directional microphones
The Swift
TX
uses two separated microphones (Left and Right) to provide a constant
transmitted voice level as the user’s head is turned from side to side.
The optimised dual microphone design also provides ideal pick up of the user’s voice and
rejects unwanted sounds in all other directions.
This means that you don’t get a variation of volume as the speaker moves their head from
side to side.
