Product Detail
The Lectrosonics DBSMD-A1B1 is a high - performance digital transmitter designed specifically for the film industry. It offers time code jam sync, allowing for seamless integration into complex production setups. With hands - free setup using audible tones, it can be put to sleep during setup when hidden in costumes to save battery, and easily awakened for operation.
It has an input gain adjustment in 1 dB increments over a 44 dB range and adjustable low - frequency audio roll - off. The selectable output power options of 10, 25, and 50 mW, along with a special 2 mW high - density (HDM) transmit mode, provide flexibility in different scenarios.
The input section features unique servo bias input circuitry with a TA5M jack, compatible with various mics and line - level signals. A DSP - controlled analog audio limiter protects the audio chain from overload. The water - resistant control panel with OLED, membrane switches, and multi - color LEDs enables quick and accurate adjustments.
This transmitter uses AA batteries (lithium recommended) and shares accessories with SMWB and SMDWB transmitters. Key features include multiple RF power selections, an ultra - lightweight and corrosion - resistant housing, an OLED interface with lockout, servo bias input, 2 - way IR port, internal recording on microSDHC card, timecode jam - sync, and high - density mode.
Technical specifications cover a wide range, including operating frequencies from 470.100 - 607.950 MHz, 25 kHz channel spacing, different RF power outputs, and various compatibility modes. The recorder on board uses a microSDHC card with a.wav file format, 24 - bit A/D converter, and 48 kHz sampling rate. It comes with several accessories like AA battery, antennas, belt clip, pouch, connector kit, and a 16 GB microSD card.
Using the Lectrosonics DBSMD - A1B1 is a breeze. First, insert the recommended lithium AA batteries into the battery compartment. Then, connect your microphone or line - level signal to the TA5M 5 - pin male input connector.
To set up the transmitter, you can use the 2 - way IR (infrared) port for fast setup. Use the water - resistant control panel with OLED, membrane switches, and multi - color LEDs to adjust input gain, select frequency, and choose compatibility modes.
When not in use, put the transmitter to sleep to save battery power. This is especially useful when it's hidden inside costumes during setup. When production starts, just wake it up for normal operation.
For recording, insert a microSDHC card into the recorder. The recorder will save files in.wav (BWF) format at 48 kHz and 24 - bit.
Some important notes: Always use recommended lithium AA batteries for best performance. Avoid exposing the transmitter to extreme temperatures outside the - 20 to 50 degrees Celsius (- 5 to 122 degrees Fahrenheit) range. Also, keep the antenna in good condition as it's a flexible, unbreakable steel cable.
For maintenance, keep the control panel clean and dry. If you notice any issues with the input limiter or audio quality, check the connections and input levels. Replace the microSDHC card regularly if you're using it for frequent recording.
