previous designs. Desired high frequency signals having

some coherence such as speech sibilance and tones are

not affected.

The Smart Noise Reduction algorithm has three modes,

selectable from a user setup screen: Off, Normal and

Full.

OFF - No noise reduction is performed and complete

transparency is preserved. All signals

presented to the transmitter’s analog front

end, including any faint microphone hiss, will

be faithfully reproduced at the receiver.

NORMAL (factory default) - Enough noise reduction

is applied to remove most of the hiss from

the mic preamp and some of the hiss from

lavaliere microphones. The noise reduction

benefit is dramatic in this position, yet the

degree of transparency maintained is

exceptional.

FULL - Enough noise reduction is applied to remove

most of the hiss from nearly any signal

source of reasonable quality, assuming

levels are set properly at the transmitter.

This additional noise reduction comes at the

cost of some transparency for low-level room

noise, yet the algorithm remains undetect-

able under most circumstances.

Note

The SmartNR setting is user selectable only in 400 Series mode. In

other modes, noise reduction is applied in such a way as to emulate

the original analog system as accurately as possible and is not user

adjustable.

LCD SCREEN

The LCD screen is used in conjunction with the MENU

control to change and control the operational settings,

and also provide a visual feedback of overall system

operation. (See FRONT PANEL MENU SELECTIONS.)

POWER SUPPLY

The R400 is operated from an external DC power source

with a range of +8 VDC to +18 VDC, up to 0.20 amperes

(200 milliamps) maximum. The receiver has a built-in

Poly-Fuse to protect the unit. If a problem occurs that

trips this fuse, it will reset after the power supply is

disconnected for about 15 seconds. The power input

section also has built-in protection circuits that prevent

damage to the receiver if a positive ground power source

is applied.

Note

The R400 requires external DC power and has no provisions for

internal batteries.
