tions.
The design of the LM400 was the direct result of numerous conversations with users,
staging and touring companies and dealers across the US. The specific concerns and
needs brought up in these conversations led directly to the development of the
operational features offered on the LM400. Two hundred fifty six frequencies are user
selectable in 100kHz steps to alleviate interference problems in traveling venues, and
the low frequency roll-off is user adjustable to adapt to varying acoustic environments
and preferences.

The LM400 is a rugged, machined aluminum package with a removable, spring loaded
belt clip. The input section provides 3.3 Volts of bias voltage to power electret mics.
Level indicating LEDs are provided on the control panel to make level settings quick
and accurate, without having to view the receiver. The battery compartment accepts
any 9 Volt alkaline battery and makes a positive connection via self-adjusting con-
tacts. The antenna is a permanently attached 1/4 wavelength flexible bronze cable.
