Both models include timecode jam synchronization, allowing them to be easily synchronized with other equipment used during production. They also support hands-free setup and adjustment through audible tones, making it possible to configure the transmitters without having to physically access the controls. A sleep mode is available to conserve battery power during setup, which is particularly useful when the transmitters are placed or hidden inside costumes. Once production begins, the transmitters can be awakened and returned to normal operation. The DBSM and DBSMD offer precise input gain adjustment in 1 dB increments across a 44 dB range. This provides detailed control over the audio input level to achieve the desired recording performance. They also feature an adjustable low-frequency audio roll-off with selectable 3 dB down points at 20, 35, 50, 70, 100, 120, and 150 Hz. This feature helps control subsonic frequencies and other very low-frequency audio content that may cause unwanted noise or affect the quality of the recorded signal.\u003c\/p\u003e\n\u003cp\u003eThe transmitters provide three selectable RF output power levels: 10, 25, and 50 mW. For situations where multiple transmitters need to operate within a limited frequency range, the DBSM and DBSMD include a special high-density mode (HDM). This mode operates at 2 mW and allows for very close channel spacing while reducing the need for extensive frequency coordination. The input section incorporates Lectrosonics’ servo-bias input circuitry and uses a standard TA5M connector. This versatile input can accommodate a range of audio sources, including electret lavalier microphones, dynamic microphones, and line-level signals. To protect the audio circuitry from excessive input levels, a DSP-controlled analog audio limiter is positioned before the first microphone preamp. The limiter provides more than 30 dB of overload protection and uses a dual-release design. This allows it to handle both short, sudden transients and longer-duration peaks while maintaining low distortion and preserving natural-sounding audio.\u003c\/p\u003e\n\u003cp\u003eFor convenient operation, the transmitters are equipped with a water-resistant control panel featuring an OLED display, membrane switches, and multi-color LEDs. These controls allow users to quickly and accurately adjust the input gain, select operating frequencies, and choose the appropriate compatibility mode. The battery compartment is designed to accept standard AA batteries, with lithium batteries recommended for reliable and extended operation. The DBSM and DBSMD are also compatible with the same accessories used with the SMWB and SMDWB transmitters. These accessories include belt clips, pouches, and battery eliminators, allowing users to easily integrate the DBSM and DBSMD into existing equipment and production setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEncrypted with AES 256 bit CTR, offering four key policies\u003c\/li\u003e\n\u003cli\u003eRF Power selections at 10, 25 and 50 mW\u003c\/li\u003e\n\u003cli\u003eUltra-lightweight, corrosion resistant housing\u003c\/li\u003e\n\u003cli\u003eOLED interface with lockout option\u003c\/li\u003e\n\u003cli\u003eServo Bias input circuitry\u003c\/li\u003e\n\u003cli\u003e2-way IR (infrared) port for fast setup\u003c\/li\u003e\n\u003cli\u003eAlternate use as recorder on internal microSDHC memory card at 48 kHz, 24 bits\u003c\/li\u003e\n\u003cli\u003eTimecode jam-sync capability with \u0026lt;1ppm accuracy\u003c\/li\u003e\n\u003cli\u003eHigh density mode for ultra-tight channel spacing\u003c\/li\u003e\n\u003cli\u003eSimultaneous record and transmit feature for models sold outside the USA.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"600\" height=\"400\" src=\"https:\/\/www.youtube.com\/embed\/SLl2wV-I2_s\" title=\"Lectrosonics DBSM and DBSMD Digital Bodypack Transmitters\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eOperating frequencies:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDBSM(D)-A1B1:\u003c\/strong\u003e Band A1-B1: 470.100 - 607.950\u003cbr\u003e\u003cstrong\u003eDBSM(D)\/E01-A1B1:\u003c\/strong\u003e Band A1-B1: 470.100 - 614.375\u003cbr\u003e\u003cstrong\u003eDBSM(D)\/E01-B1C1: \u003c\/strong\u003eBand B1-C1: 537.600 - 691.175\u003cbr\u003e\u003cstrong\u003eDBSM(D)\/E09-A1B1 Band A1-B1:\u003c\/strong\u003e 470.100 - 614-375\u003cbr\u003e\u003cstrong\u003eNOTE: \u003c\/strong\u003eIt’s the user’s responsibility to select the\u003cbr\u003eapproved frequencies for the region where the\u003cbr\u003etransmitter is operating\u003cbr\u003e\u003cstrong\u003eChannel Spacing:\u003c\/strong\u003e 25 kHz\u003cbr\u003e\u003cstrong\u003eRF Power output:\u003c\/strong\u003e DBSM: 2 (HDM only), 10, 25 or 50 mW\u003cbr\u003e\u003cstrong\u003eDBSMD:\u003c\/strong\u003e 2 (HDM only), 10, 25 or 50 mW\u003cbr\u003e\u003cstrong\u003eDBSM(D)\/E01-A1B1:\u003c\/strong\u003e 2 (HDM only), 10, 25 or 50 mW\u003cbr\u003e\u003cstrong\u003eDBSMD(D)\/E01-B1C1:\u003c\/strong\u003e 2 (HDM only),10, 25 or 50mW\u003cbr\u003e\u003cstrong\u003eDBSM\/E09-A1B1:\u003c\/strong\u003e 2 (HDM only), 10, 25 mW\u003cbr\u003e\u003cstrong\u003eDBSMD\/E09-A1B1:\u003c\/strong\u003e 2 (HDM only), 10, 25 mW\u003cbr\u003e\u003cstrong\u003eCompatibility Modes: \u003c\/strong\u003eDBSM\/DBSMD: D2 digital with encryption,\u003cbr\u003e and HDM high density digital with encryption\u003cbr\u003e\u003cstrong\u003eModulation Type: \u003c\/strong\u003e8 PSK\u003cbr\u003e\u003cstrong\u003eEncryption Type: \u003c\/strong\u003eAES-256 in CTR mode\u003cbr\u003e\u003cstrong\u003eFrequency stability: \u003c\/strong\u003e± 0.002%\u003cbr\u003e\u003cstrong\u003eSpurious radiation: \u003c\/strong\u003eCompliant with ETSI EN 300 422-1\u003cbr\u003e\u003cstrong\u003eEquivalent input noise: \u003c\/strong\u003e–125 dBV, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eInput level:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eIf set for dynamic mic:\u003c\/strong\u003e 0.5 mV to 50 mV before limiting\u003cbr\u003eGreater than 1 V with limiting\u003cbr\u003e\u003cstrong\u003eIf set for electret lavaliere mic:\u003c\/strong\u003e 1.7 uA to 170 uA before limiting\u003cbr\u003eGreater than 5000 uA (5 mA) with limiting\u003cbr\u003e\u003cstrong\u003eLine level input: \u003c\/strong\u003e17 mV to 1.7 V before limiting\u003cbr\u003eGreater than 50 V with limiting\u003cbr\u003e\u003cstrong\u003eInput impedance:\u003c\/strong\u003e\u003cbr\u003eDynamic mic: 300 Ohms\u003cbr\u003e\u003cstrong\u003eElectret lavaliere: \u003c\/strong\u003eInput is virtual ground with servo adjusted\u003cbr\u003econstant current bias\u003cbr\u003e\u003cstrong\u003eLine level: \u003c\/strong\u003e2.7 k ohms\u003cbr\u003e\u003cstrong\u003eInput limiter: \u003c\/strong\u003eSoft limiter, 30 dB range\u003cbr\u003e\u003cstrong\u003eBias voltages:\u003c\/strong\u003e Fixed 5 V at up to 5 mA\u003cbr\u003eSelectable 2 V or 4 V servo bias for any electret\u003cbr\u003elavaliere\u003cbr\u003e\u003cstrong\u003eGain control range: \u003c\/strong\u003e-7 to 44 dB;
