Table Of Contents - Lectrosonics H187 Operating Instructions And Troubleshooting Manual

INTRODUCTION
Thank you for selecting the Lectrosonics Professional Series wireless microphone
system.
This system represents well over 10 years of manufacturing experience in wireless
microphones, and almost 70 years of design experience. It is the best value avail-
able today. You will find that the H187 radiates more power than other standard
handheld wireless microphones. This provides both greater operational range, as
well as improved signal-to-noise ratio. In addition, the frequency response of the
H187 is flat to 18kHz. This guarantees that the performance of any microphone you
choose will not be degraded by the H187.
If you are new to wireless microphones, you will discover a new freedom of move-
ment and convenience. If you are an experienced wireless user, you will be pleas-
antly surprised with the effortless, quiet performance of the Lectrosonics
Professional Series design. Over time, you will appreciate the rugged dependability
of the H187. Superior mechanical design and construction mean years of trouble-
free use.
Only the H187 transmitter is covered in this manual. A matched transmitter/receiver
combination makes up a "system." Receivers are explained in separate manuals.
The H187 transmitter is constructed of metal and operates on interference-free high
band frequencies from 150MHz to 216MHz. Since the H187 uses the actual micro-
phone case as an antenna, there is no need for any unsightly extra wires. The H187
plugs into the XLR jack of any hand-held microphone, giving the user the greatest
choice of mics.
