R1a

LECTROSONICS, INC.

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.
