5.2. Parameter Control & LCD Display

5.2.1. One set of Controls for 1 or 2 Channels

Whether you have a one- or two-channel SWM6 or 7000 series receiver is ap-

parent by the number of LCD displays on the front panel. However, only one

set of control knobs is provided for either one- or two-channel receivers. Note

that in a 2-channel receiver, this set of controls is shared, and assigned to a

channel by pushing either the A or B Channel Select button (see Section

5.2.2). Your receiver uses Sabine’s Tweek-n-Peek™ digital control system.

Whenever you turn a control knob one click, the associated function is shown

on two lines of text display in the LCD. The large numeric display will indicate the

current parameter value. Additional turns/clicks change the parameter setting

and display the value as the change is made. After a few seconds of inactivity,

the LCD will revert to its default display (RF channel).

Sabine’s Tweek-n-Peek

Whenever you turn a control knob one click, the name of the corresponding

function is shown and the current edit setting is displayed on the LCD. This

applies for all the front panel knobs.

For example, if you turn the Compressor ratio knob one click, you will see the

current compression ratio in the Settings Display. The Text display will show

COMP on the ﬁrst line and RATIO on the second. Subsequent turns will edit

that setting up or down, depending on the direction you turn the knob.

Since the control knobs are continuous rotary encoders with no end points,

the Relative Position Indicator (RPI) is a handy way of seeing where you are

in relation to the full range of the knob in question. In our compressor Ratio

example, if you are at a ratio of 9:1, about the middle of the range, the RPI will

display about one half of the bar. NOTE: The setting range of each control is

printed on the front panel below each knob.

5.2.2. Channel Select / Contrast Button.

The elliptical button immediately adjacent to the LCD has multiple functions.

First, it adjusts the LCD contrast and viewing angle. Change the degree of

angle by pressing and holding the button down. The adjustment range will

cycle in a continuously reversing loop — when it gets to the maximum value

it reverses and begins to decrease in value. You can stop holding the button

down and initiate single button pushes to advance (or decrease) the contrast

setting incrementally.

In addition, the Contrast/Channel Select button has another function, in 2-

channel receivers only (SWM62 or 72-R or SWM62 or 72-NDR). Such units

feature two LCDs and two Contrast/Channel Select buttons. A single (without

continuing pressure) push assigns all Parameter Control knobs to the selected

channel. The button will light, the associated LCD will brighten, and the word

EDIT will appear in the lower left of the LCD, all indicating the active edit

channel. For the active channel, turning any Parameter Control knob will ﬁrst

display (one click) and then adjust (subsequent turns) the settings of the func-

tion selected, indicating the changes in the Settings Display. For the inactive

channel, turning any Parameter Control knob will display the current setting

in that channel’s Settings Display. The channel must be activated in order

to change settings.

Relative Position Indicator

In our compressor Ratio example, if you are at a ratio of 9:1,

about the middle of the range, the RPI will display about one

half of the bar.

Function Display

The Function display will show COMP on the ﬁrst line and

RATIO on the second.

Mic SuperModeling™ 6. Mic SuperModeling™ 6.1. Introduction Fig. 6a Microphones come in a dazzling variety of shapes, sizes, polar patterns, frequency response curves, phase response curves, etc. Few things arouse as much passion amongst audio engineers as discussions about what microphone to use in a given application. Sound rental companies and recording studios proudly tout their impressive microphone collections, and singers frequently favor a certain brand and model number as “perfect for my voice.

Mic SuperModeling™ There are no modeling settings for lavalier or headset microphones — mic placement makes these an unrealistic choice for modeling. NOTE: other lavalier microphones can be used with the Sabine Beltpack Transmitter. NOTE A very short crossfade of the audio signal occurs when switching between mic models. This ensures no digital artifacts will occur when you change the sound of the mic. 6.4.

FBX Feedback Exterminator 7. FBX Feedback Exterminator® 7.1. FBX Introduction There are two types of FBX filters, fixed and dynamic. Both operate automatically. There is no audible difference between fixed and dynamic filters in terms of sonic purity; the difference arises in their application. 7.1.1. FBX Fixed Filters Fixed filters are set automatically during the FBX SETUP and will not change frequency until manually reset. Fig. 7a SETUP Indicator Fig.

FBX Feedback Exterminator fully, and your mixer meters show little movement when signal passes through, then your amplifier will have to work harder to process the weak signal. You will improve the performance of your sound system and lower system noise by reducing the gain on your power amp and increasing your mixer gain. FBX response time will also be better with proper gain structure. 4. First, turn on your receiver and select a clear channel (no RF Signal bars showing).

Compressor Limiter 8. Compressor/Limiter Operation 8.1. Basics of Compression The dynamic range (how loud we can hear to how quiet a sound we can detect) of the human ear is far greater than the capability of sound systems to reproduce. Although some of this equipment limitation is at the upper extreme of the dynamic range (where too loud a signal will produce distortion), much of the restriction occurs at the low level end, where the signal disappears below the “noise floor” of the circuitry.
PAGE 10
Compressor Limiter Gain: (Output Level) Since the output gain is attenuated whenever the input gain exceeds the compression threshold, the overall output level of a compressed signal will be reduced. Commonly, this reduced output gain is compensated for by raising the level of the output signal (the term is “gain make-up”). Output Level range may be adjusted from mute (minus infinity) up to +20 dB, in increments of 1 dB (depending on input). 8.3. Suggested Compression Settings 8.3.1.
PAGE 11
Compressor Limiter 8.4. Possible Compression Trouble Areas Like any signal processing, compression can be misused, and improper application may cause undesirable side effects in the audio signal. Some of these problems include: 1. Noise. If the threshold for compression is set too low, and the output gain is raised substantially to make up for the gain loss of compression, the resulting output signal can be noisy.

De-esser 9. De-esser 9.1. De-mystifying De-essers Certain consonant sounds produced by the human voice contain more energy than others, and have the potential to overload a microphone capsule. This can produce a disproportionately harsh result when amplified through a sound system, and/or recorded to analog or digital storage media.

Program Save & Recall 10. Program save & recall Most wireless microphone systems provide control of one or two settings (RF channel and maybe gain). With so little to remember, the ability to save and recall system settings has not been necessary. With the Sabine Smart Spectrum® series, however, you get a very sophisticated processor with a variety of adjustable parameters. The ability to save and recall your carefully programmed setups can be a tremendous time-saver.

Multiple Systems Operation 11. Multiple Systems Operation 11.1. Overview In many circumstances a single wireless microphone system is all that will be in use at any one time. Larger applications (church, concert hall, theater stage, conference room, etc), however, can often require a large array of wireless microphones, all demanding flawless uninterrupted simultaneous operation.

Multiple Systems Operation channels to a single pair of extension antennas. See Section 12 for more information about setup and use of the SWASS-EXT. 4. Fourth, software control for the ND series receivers allows up to 70 receiver channels to be controlled from a single computer. This quick and powerful control methodology means you can monitor and change transmission channels, mic modeling, compression and de-essing — in short, all front panel controls — from a remote laptop or desktop.

Extension Antennas 12. Extension Antennas 12.1. Overview Sabine’s receivers are designed for easy interface with Sabine’s SWASS-EXT Extension Antenna Kit (figure 12b). This triangular, attractive wood-grained unit is designed to mount easily and unobtrusively on a wall (allowing either a throughthe-wall or out-the-bottom connection), or (by threading) atop a microphone stand for a more portable or temporary positioning.

Extension Antennas 1. Antenna Repositioning. Provides solutions when receiver placement options are limited or challenging. Sabine’s Extension Antenna’s multiple mounting options allow higher placement (wall mount or microphone stand mount). 2. Barriers interrupting transmission. Anytime a barrier interferes with transmission and reception, Sabine’s SWASS-EXT can be mounted on the transmitter side of the barrier with cable connections made on the receiver side.

Remote Control Operation 13. REMOTE CONTROL OPERATION 13.1. Overview NOTE: Only -NDR receivers have a USB port. You can use a USB to RS‑232 9-pin adaptor for the standard units if you need to use USB. Go to Sabine.com for a list of suggested adapters. Is this still true? In many circumstances you will adjust and control your Sabine wireless microphone system using the front panel controls, as outlined in previous sections of this operating guide.

Remote Control Operation 13.1.3. Software Multiple Unit Control The true extent of the power of the SWM Remote Software is realized when it is used to control multiple wireless receivers. When ND-series receivers are connected in a network, the additional controls offered by the Remote Software over the entire system include: • Simultaneous multiple channel/system monitoring. The Remote Software “All Channel View” (figure 13h) shows all important status conditions for up to 70 transmission channels.
