Lectrosonics IFBT5 - Manual (Page 2)

INTRODUCTION
Thank you for selecting the Lectrosonics frequency agile, narrowband, T5 IFB
transmitter. The T5 is the result of over 80 years of engineering experience with the
very latest components, in a design that addresses the most demanding profes­
sional applications.
The Lectrosonics T5 IFB Transmitter along with the companion R5 IFB Receiver
allow on-air talent to monitor program audio and receive cues from video directors
and other production personnel.
The design of the T5 IFB Transmitter was the direct result of numerous conversa­
tions with users, production personnel and dealers across the US. The specific
concerns and needs brought up in these conversations led directly to the develop­
ment of the operational features offered on the T5. Two hundred fifty six frequencies
are user selectable in 100 kHz or 25 kHz steps to alleviate interference problems in
travelling venues. 100 kHz channel spacing is standard. 25 kHz channel spacing
can be programmed into a unit by the factory or by authorized service centers.
The T5 IFB Transmitter is a rugged, machined aluminum package. The input section
is adjustable for virtually any microphone or line level audio source. Level indicating
LEDs are provided on the control panel to make level settings quick and accurate,
without having to view the receiver. The antenna is a detachable, locking 1/4 wave­
length flexible bronze cable that connects to a 50 Ohm mini-jack on the transmitter.
Only the T5 IFB Transmitter is covered in this manual. Companion receivers are
covered in separate manuals. The T5 IFB Transmitter will operate with any Lec­
trosonics R5 IFB Receiver in the same frequency group.
