LECTROSONICS, INC. 2
Introduction
Thank you for selecting the Lectrosonics frequency
agile, R1a IFB receiver. The design is the result of
extensive engineering experience with the most up to
date components for demanding professional applica-
tions. The receiver will operate with any Lectrosonics
IFB Transmitter.
The Lectrosonics R1a receiver along with the compan-
ion T1 or T4 transmitter allow on-air talent to monitor
program audio, and to receive cues from directors and
other production personnel.
The housing is a rugged, machined aluminum package
designed to survive abusive environments
Only the R1a IFB receiver is covered in this manual.
Transmitters are covered in separate manuals.
The R1a will also work with later models of Digital Hy-
brid Wireless transmitters in the same frequency block.
Check with the factory regarding compatibility with the
firmware in your transmitter.
Safety Notes
Excessive sound levels can cause permanent hearing
damage.
1. Always adjust the volume to the lowest level before
listening to unknown transmissions.
2. Use the lowest reasonable level consistent with
hearing safety.
3. Don’t use high sound levels in the earphone to
overcome high ambient sound levels. That is
absolutely foolish! Demand and use high isolation
earphones.
4. Don’t expose your ears to sound levels that cause
them to ring. If your ears do ring after exposure,
think of it as a warning bell telling you not to do
that again.
OSHA (Occupational Safety Health Administration)
guidelines on the maximum allowable time exposure to
sound pressure levels that will cause hearing damage
are as follows:
8 hours at
90 dB SPL
4 hours at 95 dB SPL
2 hours at 100 db SPL
1 hour at 105 dB SPL
30 mins at 110 dB SPL
15 mins at 115 dB SPL
NEVER expose your ears to 120 dB SPL or higher!
Damage will occur.
