Product Detail
The Lectrosonics DBSM-A1B1 digital transmitter is a game - changer designed specifically for the film industry. It comes with a built - in recorder and time code jam sync capability. With hands - free setup and adjustment using audible tones, you can conserve battery power by putting it to sleep during setup, especially when it's hidden inside costumes. Then, just wake it up when production starts. This transmitter offers input gain adjustment in 1 dB increments over a 44 dB range and adjustable low - frequency audio roll - off, giving you great control over subsonic and very low - frequency audio. You can select output power of 10, 25, or 50 mW, and there's a special 2 mW high - density (HDM) transmit mode for ultra - tight channel spacing without frequency coordination worries. The input section features unique servo bias input circuitry with a TA5M jack, suitable for electret lavaliere mics, dynamic mics, or line - level signals. A DSP - controlled analog audio limiter protects the audio chain from overload, with over 30 dB range and a dual - release envelope for low - distortion performance. The water - resistant control panel with OLED, membrane switches, and multi - color LEDs makes input gain, frequency, and compatibility mode selection fast and accurate. It uses industry - standard AA batteries (lithium is recommended). Key features include AES 256 - bit CTR encryption with four key policies, an ultra - lightweight and corrosion - resistant housing, an OLED interface with a lockout option, a 2 - way IR port for fast setup, and the ability to record on an internal microSDHC card at 48 kHz, 24 bits. Technical specifications show it operates from 470.100 - 607.950 MHz with 25 kHz channel spacing, has various RF power outputs, and multiple compatibility modes. It offers excellent frequency stability, low equivalent input noise, and a wide dynamic range. The included accessories make it ready to use right out of the box.
Using the Lectrosonics DBSM - A1B1 is easy. First, insert a recommended lithium AA battery into the battery compartment. Connect your electret lavaliere mic, dynamic mic, or line - level device to the TA5M 5 - pin male input connector. You can adjust the input gain using the membrane switches on the water - resistant control panel with OLED display. Select the appropriate frequency and compatibility mode according to your needs. If you want to use the recorder function, insert a microSDHC card. During setup, you can put the device to sleep to save battery power, and wake it up when you're ready to start recording or transmitting. Remember to operate it within the temperature range of - 5°F to 122°F (- 20°C to 50°C). When not in use, store it in a dry place. Clean the control panel gently with a soft, dry cloth. Avoid exposing it to water or excessive moisture, as it's only water - resistant, not waterproof. Check the battery regularly and replace it when it runs low to ensure continuous operation. If you're using the high - density (HDM) mode, enjoy the ultra - tight channel spacing without the need for frequency coordination.
