High performance, frequency synthesized transmitter with BNCRF output in place of mic input jack, dedicated aux or line-level input, and extended low-frequency response. Includes C-216 carrying case, SLW-216 loaded flexible helical antenna with BNC connector.

The M-216 Option P7 is the perfect on-the-go field transmitter offering directors, crew, and client reliable and superior sounding wireless program monitoring. For use with the PR-216 or PR-216 Option 7 wireless receivers, this portable, battery-powered transmitter is built to withstand the most demanding needs of location sound monitoring. Equipped with a flexible short whip antenna, the M-216 Option P7 offers superior RF transmission and a greater operating range. It has an adjustable gain control and a single LED VU meter that offers a quick visual reference to indicate audio input level.

Frequency synthesized base station transmitter with dual function audio processing for transmission of both standard or high-fidelity channels.

The BST 25-216 transmitter incorporates the latest digital and analog technologies to produce low residual noise, wide dynamic range, and extended frequency response rendering the most natural sound possible for a wireless system. For the highest-fidelity operation, the PR-216 receiver can be used on the wide-band companded channels. The BST 25-216 is also compatible with other manufacturer’s all-in-ear type receivers operating in the 216-217 MHz band on the narrow band non-companded channels with a special EQsetting. The transmitter’s microcontroller automatically sets the modulation deviation and the audio mode for companding processing when corresponding channels are selected.

Band A1

The HMa will ideally match any microphone or line-level source, with its wide input gain range of 44dB and wide tuning range of 76 MHz in 100 kHz or 25 kHz steps for up to 3072 frequencies per band. A USB port makes firmware updates possible in the field. The HMa is ideal for a variety of wireless microphone applications including wireless boom, plant miking, and ENG in particular.

The HMa combines 24-bit digital audio with analog FM transmission resulting in superior radio reliability with superb audio performance. Audio frequency response of the HMa is 40 Hz-20 kHz+-1dB. Phantom power is selectable at 5, 15, and 48 volts, or can be turned off for use with dynamic microphones and line-level signal sources. The patented Digital Hybrid Wireless process delivers compander‐free audio and uses an analog FM carrier to transmit a specially encoded signal which delivers digital audio quality while spectrum efficient. The signature cam lock and quick-release mechanism make it easy to securely attach any microphone then detach it in seconds. Runs on AA batteries.

To meet the demands for a variety of RF environments and applications, the “WB” series SM transmitters offer selectable output power of 25, 50, and 100 mW (25 and 50 mW for export versions). With higher power output, the operating range is improved, or, a more secure link can be relied upon for high RF noise environments. Battery life is unchanged with the different RF power selections.

The transmitters offer hands-free setup and adjustment using audible tones. They can be put to sleep to conserve battery power during setup while buried inside costuming, then awakened for normal operation when the production begins. Other features include input gain adjustment in 1 dB increments over a 44 dB range and adjustable low-frequency audio roll-off for 3 dB down points at 35,50, 70, 100, 120, or 150 Hz to control subsonic and very low-frequency audio content.

To meet the demand for both extended operating range and extended battery life, the “V” series SM transmitters offer selectable output power. A third selection at 50 mW is provided for some theatrical applications where the system design specifies lower transmitter power.

The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line-level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short-term dynamics
