It is best to keep the system’s channels close together at the low

or high end of the spectrum, i.e.channels 1, 2,3,4,5 or channels 65,

66, 67, 68. If there is another 2.4 GHz source in the room, grouping

the channels reduces the chances of an overlap. Do not start by spread-

ing your channels throughout the 70 channel range of the system --

you are more likely to encounter interference this way. See step 3 for

the controls used to select RF channels.

COMPRESSOR/LIMITER

Vocal Settings

RATIO

A soft voice could be set to 2:1, whereas a loud

voice might require a ratio setting of 6:1.

THRESH

The higher the threshold setting, the more signal

is required to initiate compression. Ideally this

should be set to reign in peak levels, and allow

signals of lower gain to pass uncompressed.

Threshold settings will depend on the nature and

variety of the signal source.

ATTACK

Short attack times usually work well for voice. How-

ever, too strong a compression ratio, too low a

threshold, and too fast an attack may attenuate

speech consonants, which provide important in-

telligibility cues to the audience, thus compromis-

ing clarity.

Guitar Settings

RATIO

A high compression ratio (with gain makeup) will

add sustain to held notes and chords.

THRESH

Moving the threshold will change the audible thick/

thinness of the guitar tone, but generally you want

to compress all the notes played.

ATTACK

Be wary of too quick an attack, which may reduce

the percussive attack of the guitar notes.

In general, be wary of too much gain makeup, and too high a

compression ratio, which may make a noisy guitar amplifier

more objectionable. Ratio settings might range from 6 to 19:1,

threshold variable, slower attack, soft knee, output gain

boosted slightly to significantly depending on amount of com-

pression.

Bass Guitar Settings

Set to 4:1

THRESH

ous release settings, depending on the speed of

notes played).

Press and hold the SETUP button

LCD SETUP indicator (Fig. 3e)

flashes 4 times and SETUP stays

lit —then release it.

Location #1

Location #2 Location #3

NOTE: When choosing microphone setup locations, try to anticipate likely areas where the microphone will be

positioned or moved to, or areas that may be especially prone to feedback problems (e.g., under an overhead

speaker).

FBX Quick Setup

(to be done after Transmitter and Receiver Setups have been completed)

Place microphone and speakers in primary position.

Slowly raise the gain on the

mixer or amp until FBX eliminates

the first few feedback tones. With

each new feedback frequency, you

will hear a short, quiet burst of feed-

back that will disappear immediately

as a filter is set.

Pause raising the gain, and move the

microphone to another area where

it will be used. Resume slowly rais-

ing the mixer gain, until FBX elimi-

nates a few more feedback tones.

Location #4

(if necessary)

Repeat until the SETUP indicator automatically turns

off and the READY indicator comes on.

NOTE: You may quit SETUP mode at any time prior to its

automatic exit by simply pressing the READY button.This will

enable ready-to-operate status, but with fewer fixed FBX fil-

ters in place. In the default factory setting, dynamic FBX fil-

ters will still be held in reserve to catch and eliminate new

feedback, regardless of how or when SETUP mode is exited.

See Section 14.3.2 for details on the differences between fixed and dynamic FBX filters.See Section 13.4.2.1

for instructions on changing the balance of fixed versus dynamic FBX filters using the Remote Control Software

(or Appendix D for using the Dip Switches on the back of the receiver).

Bypass Button

The BYPASS button bypasses only the FBX filters, and not the additional signal processing (de-essing, com-

pression and Mic SuperModelingTM) available on the True MobilityTM Wireless Receiver.This is a useful button

that allows comparison of the sound quality when FBX filters are in place, to the sound with no filters (the quality

should be very similar). Before pressing BYPASS, take care to reduce your overall system gain so that

you do not release suppressed feedback!

FBX BYPASS CAUTION

Bypassing FBX filters may allow suppressed feedback to be released!

Common Sources of RF Interference

It is best to keep the system’s channels close together at the low or high end of the spectrum, i.e.channels 1,

2,3,4,5 or channels 65, 66, 67, 68. If there is another 2.4 GHz source in the room, grouping the channels reduces the

chances of an overlap. Do not start by spreading your channels throughout the 70 channel range of the system - -you

are more likely to encounter interference this way.

Avoid potential sources of RF interference by performing a scan using Sabine’s Remote Control Software, which will

reveal the ambient RF level in your area on each channel of your system.Please refer to Section 13.4.2.5.for informa-

tion on the RF Scan function, which will automatically determine the best RF channels to use.

If you cannot perform a scan then proceed to use your system, beginning with Channel 1 and keep your chan-

nels grouped together. If you hear any RF “hits”or dropouts, then try another of the 70 available channels.

For best results, maintain line-of-sight from transmitter to receiver. Use either front or rear panel antenna mount-

ing to maintain line-of-sight.This is very important!

Mount receiver antennas at 90 degrees to one another, leaning away at 45 degree angles, in the same plane.

When using multiple receivers, try to maintain at least 1 foot (30 cm) distance between antennas from different

units.When such antenna spacing proves difficult or impossible, we recommend using Sabine’s SWA6SS An-

tenna Distribution Amplifier. The SWA6SS works with up to six receivers, or 12 channels.

Maximize the distance between the receiver and light sources, such as fluorescent bulbs or neon signs, which may

emit very short-range, broadband interference.

Maximize the distance between transmitters and receivers and potential sources of RF interference, as shown below.

Maintain a minimum distance of at least 3 meters (10 feet) between transmitters and receivers or extension

antennas.This can solve many anomalies.

Be careful not to set more than one transmitter to the same channel; each paired transmitter and receiver should

be set to unique corresponding channels, until all channels are receiving clearly and cleanly.

SWM7000 Receivers

Microwave ovens Microwave ovens will likely present a problem only when located in fairly close proximity within

the same room as the wireless receiver (or reception antenna).See caution below.

Wireless Local Area Networks (WLANS) In general, Sabine microphones should not be affected by these

WLANS. Use the RF scanner included in Sabine because their spread spectrum technology does not present a

problem for the Sabine Smart SpectrumTM system. See caution below.

Cordless phones These home telephones broadcast at very low power and should not present interference

problems for your Sabine wireless.This is especially true if the telephone uses spread spectrum technology.

WirelessVideo Cameras These devices are also very low power and, in general, should not present a problem

when using the SWM7000 system. See Section 5 Receiver Operation for methods of optimizing clear reception and

minimizing interference. See caution below.

As a general precaution, keep 2.4 GHz cordless telephones, microwave ovens, WLAN antennas and 2.4 GHz wireless

video camera transmitters twice the distance from your Sabine wireless microphone system antennas as that of your

Sabine 2.4 GHz transmitters.
