Introduction

The DSSM is the enhanced, fully digital successor to the SSM, while being IP57 rated for moisture and particulate resistence and offering dock charging capability.
The DSSM is ideal in theater, TV, film and broadcast where concealment is desired and water-resistance is required. The DSSM offers an extensive feature set and performance packed into an exceptionally compact housing, compatible with all current Lectrosonics digital receivers, including the DSR, DSR4, DSQD, DCR822, M2Ra and DCHR.
The DSSM includes specially developed, highly efficient circuitry for extended operating time on the rechargeable LB-50 battery. RF power selections are offered at 10 and 35 mW (D2 compat mode) and a special high density (HDM) mode at 2 mW.
The servo bias input accepts mic or line level signals with a wide range of gain adjustment in 1 dB steps. Accurate indications on the display allow precise gain adjustments to be made for the maximum signal to noise ratio and minimum distortion. The limiter in the preamp can cleanly handle signal peaks over 30 dB above full modulation, allowing the input gain to be set high enough to achieve the maximum signal to noise ratio, yet provide protection against input overload.
The audio input jack is a common miniature 3-pin connector with a threaded collar adding additional ruggedness. An IR (infrared) port next to the SMA antenna mount allows transfer of frequency and compatibility mode settings.
The membrane switch panel and OLED display enable access to all adjustments and settings. The menu struc-

ture is easy to navigate. Battery status is indicated by a bi-color LED that is green with a fresh battery, then turns to red as the battery runs down, and finally starts blinking red when there are only a few minutes of runtime remaining.
The housing is constructed of machined aluminum alloy, treated in the conductive, super hard electroless nickel ebENi finish.
A flexible, repositionable wire belt clip (to orient the antenna facing up or down) is included.
The optional CHSDSSM battery charging station (shown below) provides a convenient and organized means of recharging up to 4 LB-50 batteries or DSSM transmitters in larger systems with numerous batteries in regular use. Each charging module may be daisy-chained to 3 additional modules using a single AC-DC power supply.

What is IP57?
IP ratings indicate how resistant an electrical device is to water and common materials – like dirt, dust and sand. The DSSM’s IP57 rating indicates that that it is water resistant up to 1 meter (3.2 feet) for 30 minutes – perfect for your most demanding environments.

600MHz Wireless Guard Band and Duplex Gap

You’ll notice that our B1C1 range for North America takes advantage of two sets of spectrum space within the 600 MHz band, as designated by the FCC auction. The 600 MHz band is made up of the following four parts:
Guard Band (614-617 MHz) Downlink Band (617-652 MHz) Duplex Gap (652-663 MHz) Uplink Band (663-698 MHz)

The Guard Band consists of: 614-616 MHz: 2 MHz (unlicensed operators) 616-617 MHz: 1 MHz buffer (unavailable for use)
The Duplex Gap consists of: 652-653 MHz: 1 MHz buffer (unavailable for use) 653-657 MHz: 4 MHz (licensed operators only) 657-663 MHz: 6 MHz (unlicensed and WSDs)

Wireless microphone devices in North America are limited to the Guard Band (614-617 MHz) and Duplex Gap (652-663 MHz).

Power is limited to 20mW for wireless microphones used in this part of the spectrum.

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. See the Adjusting Input Gain section for additional information.

KeyType
The DSSM receives an encryption key via the IR port from a key generating receiver. Begin by selecting a key type in the receiver and generating a new key (key type is labeled KEY POLICY in the DSQD receiver). Set the matching KEY TYPE in the DSSM and transfer the key from the receiver (SYNC KEY) to the DSSM via the IR ports. A confirmation message will display on the receiver display if the transfer is successful. The transmitted audio will then be encrypted and can only be listened to if the receiver has the matching encryption key.

KeyType Univrsal

The encryption system in Lectrosonics Digital modes D2 and HDM may be configured in four different ways, determined by a parameter known as the Key Type. The four key types range from least secure but most convenient, to most secure but least convenient. Below are descriptions of the four Key Types and how they work.
· Universal: This is the default key type, the simplest to use, and the least secure. While encryption is technically being performed and a scanner or simple demodulator would not reveal the signal content, communications are not truly secure. This is because all Lectrosonics products employing

Water-Resistant Micro Body Pack Transmitter

the Universal key type use this same “universal” encryption key. With this key type selected, keys do not need to be created or exchanged, and wireless devices can be used without attention to the encryption feature.
· Shared: This is the easiest encryption mode to use while employing a uniquely generated key. This key type offers excellent security and considerable flexibility. Once a key has been created, it can be shared an unlimited number of times with any compatible device which, in turn, can also share the key. This is especially useful when multiple receivers may need to pick up various transmitters.
· Standard: The Standard key type offers enhanced security, at the cost of some complexity. Standard keys are “instance controlled”, which allows the hardware to protect against “differential attacks”. A Standard key can only be sent by the device that created it, and only up to 256 times. Unlike with Shared keys, devices receiving a Standard key cannot pass it on.
· Volatile The Volatile key type is the most secure, and also the least convenient to use. Volatile keys behave identically to Standard keys, except that they are never stored. Equipment which is turned off while using a Volatile key will come back on with no key. If a key-generating device is left on, the key can be re-shared with units in the system that have lost their keys. Once all equipment having used a given Volatile key is powered off, that key is effectively destroyed. This may be required in some highly secure installations.
WipeKey
This menu item is only available if Key Type is set to Standard, Shared or Volatile. Select Yes to clear the current key.

Selecting Mic/Audio Input Configuration
Refer to Page 12 for detailed information on configuring Line and Instrument level inputs.
IR Sync
An IR (infrared) link between an associated receiver and the transmitter can be used to shorten setup time and ensure that the correct settings in the transmitter are made. The window on the top panel of the transmitter is the port used for the IR link. The receiver is normally used to identify a clear operating frequency. Once step size, frequency and compatibility mode are set in the receiver, the settings can be sent to the transmitter via this IR link.
Place the transmitter close to the IR enabled receiver with the ports facing each other a few inches apart. Send the settings with the trigger on the receiver. If the settings are successfully transferred, a confirmation message will appear on the transmitter and receiver displays.
NOTE: If a mismatch exists between the receiver and transmitter, an error message will appear on the units.
Reversible Belt Clip
The belt clip may be removed or reoriented (to point the antenna up or down) by carefully lifting it out and off of the housing, with the battery door open. Pull the one side of the wire out of the grooved hole as shown, then upward to remove. Repeat for the opposite side.

Whip Antennas
Because the transmitter tunes across such a broad frequency range, it is best to use the appropriate antenna for maximum operation. Two antennas are included with the transmitter, and are shipped from the factory pre-cut and fully assembled with a 50 Ohm SMA connector.
Each antenna covers three blocks. Use the chart below to determine which antenna best fits your needs.

LectroRM
By New Endian LLC
LectroRM is a 3rd party mobile application for iOS and Android smart phone operating systems. Its purpose is to make changes to the settings on select Lectrosonics transmitters by delivering encoded audio tones to the microphone attached to the transmitter. When the tone enters the transmitter, it is decoded to make a change to a variety of different settings such as input gain, frequency and a number of others.
The app was released by New Endian, LLC in September 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 sequence 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

Android
The Android version keeps all settings on the same page and allows the user to toggle between the activation 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.
Remote Control and Activation
Remote control signals (“dweedle tones”) may be used to control the transmitter. The tones are played back into the microphone to avoid the need to reach and handle the transmitter when making changes to the adjustments and settings. For a transmitter to respond to remote control audio tones, the transmitter must meet certain requirements:
· The transmitter must be turned on. · The transmitter microphone must be within
range. · The remote control function must be enabled on
the transmitter. See page 15.
Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com.

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 bottom of the device, closer to the transmitter microphone.

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 connection, 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:
A. DO NOT return equipment to the factory for repair without first contacting us by email 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).
B. 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.
C. 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.
D. 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.
