Introduction Three Block Tuning Range

The SSM transmitter tunes across a range of over 76 MHz. This tuning range covers three standard Lectro-sonics frequency blocks.

Four tuning ranges are available covering standard blocks as follows

About Frequency Blocks

A 25.6 MHz band of frequencies, referred to as a Block, came about with the design of the first frequency tunable Lectrosonics wireless products. These prod-ucts provided two 16-position rotary switches to select frequencies as shown in the illustration below. A logical method of identifying the switch positions was using 16 character hexadecimal numbering. This naming and numbering convention is still used today. The 16 switch positions are numbered 0 (zero) through F, presented in a two-character designation such as B8, 5C, AD, 74, etc. The first character indicates the position of the left hand switch and the second charac-ter indicates the position of the right hand switch. This designator is commonly called a hex code.

On older transmitter models, the left hand switch makes steps in 1.6 MHz increments, the right hand switch in 100 kHz increments.Each block spans a 25.6 MHz band. A simple formula is used to name the blocks according to the lowest frequency in each one. For example, the block starting at 512 MHz is named Block 20, since 25.6 times 20 equals 512.

About Digital Hybrid Wireless

US Patent 7,225,135

All wireless links suffer from channel noise to some degree, and all wireless microphone systems seek to minimize the impact of that noise on the desired signal. Conventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sending the audio informa-tion in digital form, however, it is often at the cost of one or more issues regarding power, bandwidth, operating range and resistance to interference.
The Lectrosonics Digital Hybrid Wireless system over-comes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded informa-tion via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique which can be accomplished only in the digital domain. Since the RF link between transmitter and receiver is FM, channel noise will increase gradually with in-creased operating range and weakened signal condi-tions; however, the Digital Hybrid Wireless system handles this situation elegantly with barely audible audio artifacts as the receiver approaches its squelch threshold.In contrast, a purely digital system tends to drop the audio suddenly during brief dropouts and weak signal conditions. The Digital Hybrid Wireless system simply encodes the signal to use a noisy channel as efficiently and robustly as possible, yielding audio performance that rivals that of purely digital systems, without the power, noise and bandwidth problems inherent in digital transmission. Because it uses an analog FM link, Digital Hybrid Wireless enjoys all the benefits of conventional FM wireless systems, such as excellent range, efficient use of RF spectrum, and long battery life.

Battery Installation

The battery compartment and door catch are designed for simple and quick battery changes, yet prevent the door from being opened accidentally.

CAUTION
Use only the factory supplied battery and battery charger.

WARNING
Risk of explosion if the battery is replaced by an incorrect type.

Battery Charging

The transmitter operates from a 3.6 V rechargeable battery that will provide about six hours of operation per charge. Battery life can be monitored from the timer function built into current Lectrosonics receivers.

The factory supplied battery charger kit provides a folding NEMA 2 prong plug on the charger, and will operate from 100-240 VAC sources. The LED glows red during charging and turns green when the battery is fully charged. The kit includes a Euro plug adapter and vehicle auxiliary power adapter cord. SSM/E01 units do not ship with a charger. Order ZS-SSM/E01 kit 4 different kits for different frequency bands, which includes the charger.

Controls and Functions

Modulation LEDs

Proper input gain adjustment is critical to ensure the best audio quality. Two bicolor LEDs will glow either red or green to accurately indicate modulation levels. The input circuitry includes a wide range DSP controlled limiter to prevent distortion at high input levels. It is important to set the gain audio level high enough to achieve full modulation during louder peaks in the audio. The limiter can handle over 30 dB of level above full modulation, so with an optimum setting, the LEDs will flash red during use. If the LEDs never flash red, the gain is too low. In the table below, +0 dB indicates full modulation.

LCD Screen

The LCD is a numeric-type Liquid Crystal Display with screens for adjusting output power, frequency, audio level, low frequency audio roll-off and various modes and options. The transmitter can be powered up with or without the RF output turned on. A brief press on the power button turns the unit on in a Standby Mode with the output turned off to allow adjustments to be made without interfering with other wireless systems in the vicinity.

WARNING
Moisture, including talent’s sweat, will damage the transmitter. Wrap the SSM in a plastic baggie or other protection to avoid damage.

BATT LED

This LED glows green when the battery is good. The color changes to red when there is only a few minutes of operation left. The LED will blink briefly, just before the unit powers down. The exact point at which the LED turns red will vary with battery brand and condition, temperature and cur-rent drain. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time.

AUDIO Button

The AUDIO button is used to adjust the audio output level and low frequency roll-off. Each press of the button will toggle between the two settings.

FREQ Button

The FREQ Button displays the selected operating frequency and toggles the LCD between displaying the actual operating frequency in MHz and a two-digit hexadecimal number that corresponds to the equivalent Lectrosonics Frequency Switch Setting.

Power Button

Turns the unit on and off. A brief press turns power on in a Standby Mode to make settings without interfering with other wireless systems in the vicinity. Pressing and holding the button until a counter on the LCD completes a sequence turns the power on with the RF output turned on. Pressing and holding for the duration of a countdown turns the unit off.

UP and DOWN Arrow Buttons

The Up and Down arrow buttons are used to select the values on the various setup screens and to lock out the control panel.

Turning LEDs ON and OFF

These arrow keys also turn the LEDs on and off. With no other button pressed, the UP arrow turns the LEDs on and the DOWN arrow turns them off. When the LEDs turn red, the LCD will display a reminder every few seconds.

Connectors and USB Port

The housing is machined out of a solid aluminum billet for a rugged, lightweight assembly.

The antenna is a flexible whip made of galvanized steel, permanently attached to the transmitter to prevent damage from heavy use. The IR port is capped with
a translucent dome material to broaden the reception angle. The input jack is a rugged 3 pin LEMO connector with a threaded locking sleeve. The opposite end of the transmitter contains the battery door latches and release tabs, and the USB port, which is used for firmware updates.

The battery door itself is made of stainless steel to allow a thin wall thickness, but retain the strength to withstand heavy use.

Attaching and Removing the Microphone

Align the ridges on the plug with the grooves in the jack and insert the plug.

Slide the threaded sleeve onto the jack and rotate it clockwise to tighten it.

Operating Instructions

Powering On in Operating Mode

Press and hold the Power Button for several seconds until a counter on the LCD progresses from 1 through 3, followed by a display of the model, firmware version, frequency block and compatibility mode.

When you release the button, the unit will be operational with the RF output turned on and the Main Window displayed.

Powering On in Standby Mode

A brief press of the Power Button , releasing it before the counter has reached 3, will turn the unit on with the RF output turned off. The LCD will display a reminder that the RF output of the transmitter is turned off.

In this Standby Mode the frequency can be browsed to make adjustments without the risk of interfering with other wireless systems nearby. After adjustments are made, press the power button again to turn the unit off.

Powering Off

Holding the Power Button in and waiting for the completion of the countdown from 3 to 1 will turn the power off.

If the power button is released before the countdown is completed, the unit will remain turned on and the LCD will return to the same screen or menu that was dis-played previously.

Setup Screens

Two different setup menus are accessed by holding either the UP or DOWN arrow button while powering the unit on for a listing of the menu items and descriptions.

Screens Used in Normal Operation

When the transmitter is turned on with the RF output on, the LCD will display the frequency, audio gain or LF roll-off point. Audio gain is expressed in dB.

Frequency is displayed in one of two ways

Frequency expressed in MHz

LF roll-off is expressed in Hz.

To make changes to the settings, press either button to display the desired screen, then use the UP and DOWN arrows to select the value. The changes take effect im-mediately when you release the buttons.

Block 470/19 Frequency Overlap

Frequencies 486.400 495.600 Overlap in Blocks 470 and 19. Block 470 and block 19 overlap each other in the frequency range from 486.400 to 495.600 MHz. Since block 470 starts at a lower frequency than block 19, the hex codes and pilot tones will not match even though the frequencies are the same in the overlap zone. When using a transmitter on the A1 band with a block 19 receiver be sure the transmitter is set to block 19 and check the hex code on the receiver to make sure it matches the transmitter. Call the factory if you have questions about this issue.

Setup Steps

The setup menus are accessed by holding either the UP or DOWN arrow while powering the unit on. Refer to Setup Screens on the next page for details of each setup parameter. The following list outlines the steps necessary to set up the transmitter for normal use. Install a charged battery. Set the compatibility mode to match the receiver to be used.  Adjust the step size and frequency to match the receiver. The frequency is normally determined us-ing the receiver to identify one within clear operating spectrum.

NOTE
Some Lectrosonics receivers include an IR (infrared) port to transfer settings from the receiver to the transmitter. Connect the microphone or audio source to be used. Select the correct input configuration.  Adjust the input gain.Turn on the receiver and verify that solid RF and audio signals are present.

Locking the Controls

The firmware version is displayed briefly when powering up the transmitter.

For firmware versions 1.06 and lower

Lock the controls by holding the UP and DOWN arrows until a count displayed on the LCD is completed and Loc appears on the LCD. To unlock the controls, remove the battery.

For firmware versions 1.07 and higher

Lock the controls by holding the UP and DOWN arrows until a count displayed on the LCD is completed and Loc appears on the LCD. To unlock the controls, hold the UP and DOWN arrows until a count on the LCD is completed and unloc appears on the LCD. Removing the battery does not unlock the controls.

Adjusting the Input Gain

The two bicolor Modulation LEDs on the control panel provide a visual indication of the audio signal level entering the transmitter. The LEDs will glow either red or green to indicate modulation levels as shown in the following table

Greater than +10 dB

&nbsp

|  Red|  Red

NOTE
Full modulation is achieved at 0 dB, when the 20 LED first turns red. The limiter can cleanly handle peaks up to 30 dB above this point.It is best to go through the following procedure with the transmitter in the standby mode so that no audio will enter the sound system or recorder during adjustment.

1. With a charged battery in the transmitter, power the unit on in the standby mode numeral on the display e.g. Aud 22
2. Prepare the signal source. Position a microphone the way it will be used in actual operation and have the user speak or sing at the loudest level that occur during use, or set the output level of the instrument or audio device to the maximum level that will be used.
3. Use the and arrow buttons to adjust the gain until the 10 dB glows green and the 20 dB LED starts to flicker red during the loudest peaks in the audio.
4. Once the audio gain has been set, the signal can be sent through the sound system for overall level adjustments, monitor settings, etc.
5. If the audio output level of the receiver is too high or low, use only the controls on the receiver to make adjustments.
6. Unless the microphone or its position changes, or a different instrument is being used leave the transmitter gain adjustment set according to these instructions.
7. Use the audio output level control on the receiver to make adjustments for the desired level being delivered to the connected mixer, recorder etc.

LectroRM

By New Endian LLC

LectroRM is a mobile application for iOS and Android smart phone operating systems. Its purpose is to make changes to the settings on select Lectrosonics transmit-ters by delivering encoded audio tones to the micro-phone attached to the transmitter. When the tone enters the transmitter, it is decoded to make a change to a va-riety of different settings such as input gain, frequency and a number of others. The app was released by New Endian, LLC in Septem-ber 2011. The app is available for download and sells for $25 on the Apple App Store and Google Play Store. The settings and values that can be changed vary from one transmitter model to another. The complete list of available tones in the app is as follows

• Input gain.
• Frequency.
• Sleep Mode.
• Panel LOCK/UNLOCK.
• RF output power.
• Low frequency audio roll off.
• LEDs ON/OFF.

The user interface involves selecting the audio se-quence related to the desired change. Each version has an interface for selecting the desired setting and the desired option for that setting. Each version also has a mechanism to prevent accidental activation of the tone.

IOS

The iPhone version keeps each available setting on a separate page with the list of options for that setting. On iOS, the Activate toggle switch must be enabled to show the button which will then activate the tone. The iOS version’s default orientation is upside down but can be configured to orient right-side up. The purpose for this is to orient the phone’s speaker, which is at the bot-tom of the device, closer to the transmitter microphone.

Android

The Android version keeps all settings on the same page and allows the user to toggle between the activa-tion buttons for each setting. The activation button must be pressed and held to activate the tone. The Android version also allows users to keep a configurable list of full sets of settings.

Activation

For a transmitter to respond to remote control audio tones, the transmitter must meet certain requirements

• The transmitter must be turned on.
  The transmitter must have firmware version 1.5 or later for Audio, Frequency, Sleep and Lock changes.
  • The transmitter microphone must be within range.
  • The remote control function must be enabled on the transmitter.

Service and Repair

If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables. We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connec-tion, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.  LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out of warranty repairs.

Returning Units for Repair

For timely service, please follow the steps below

• DO NOT return equipment to the factory for repair without first contacting us by e-mail or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M U.S. Mountain Standard Time.
• After receiving your request, we will issue you a return authorization number R.A
• This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
• Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS or FEDEX is usually the best way to ship the units. Heavy units should be double boxed for safe transport.
• We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
