Sennheiser SZI-30 Emitter Panel

$0.00

The Sennheiser SZI 30 is a slave infrared (IR) emitter panel designed to extend the coverage area of an SI 20 or SI 30 transmitter in an infrared wireless audio system. It's a wideband modulator with an integral radiator and can be used to create a wider or longer throw of the IR signal. Up to three SZI 30 units can be added to an SI 20 to increase coverage.

View Product Features

Slave Emitter : Designed to be connected to and controlled by an SI 20 or SI 30 transmitter.
Extended Coverage : Increases the effective coverage area of the main transmitter.
Carrier Frequencies : Operates on channel 1 (2.3 MHz) or channel 2 (2.8 MHz).
Coverage Area : Can provide up to 80 square meters of coverage.
Power : Requires a DC power supply, such as the NT20-1-UK (power supply not included).
Mounting : Can be mounted on ceilings or walls using appropriate mounting hardware (e.g., IZK20 mounting clamp).
Automatic Gain Control : Ensures consistent signal strength in multi-panel setups.

About the Sennheiser SZI-30 Emitter Panel

The Sennheiser SZI-30 is an infrared emitter panel designed for high-performance audio transmission in professional infrared listening systems. Its primary function is to broadcast audio signals from a base station or mixer as modulated infrared light, which is then picked up by compatible infrared receivers and headphones worn by users. This technology provides a confidential, interference-free, and license-free wireless audio solution, making it indispensable in applications where radio frequency transmission is impractical or prohibited, such as in courtrooms, theaters, houses of worship, museums, and multilingual interpretation facilities. The panel is engineered to deliver uniform coverage across a defined listening area with high signal clarity and stability.

Constructed with a array of high-power infrared diodes, the SZI-30 emitter panel offers a wide angle of dispersion to effectively illuminate large spaces. Its design prioritizes consistent signal strength to prevent dropouts or dark spots within the coverage zone, ensuring every listener receives a reliable audio feed. The panel is typically designed for permanent ceiling or wall mounting, often in a daisy-chain configuration where multiple panels can be linked together to cover expansive or irregularly shaped rooms. This scalability allows system integrators to tailor the infrared coverage precisely to the architectural requirements of the installation.

The panel operates as a core component of a complete infrared system, requiring connection to a compatible infrared transmitter or modulator that provides the audio signal and powers the emitter diodes. It is built for reliability and long-term operation in demanding 24/7 environments, with a robust housing that protects the internal components. By converting audio into an invisible light signal, the Sennheiser SZI-30 provides a secure and robust method for delivering confidential or language-specific audio to audiences, fulfilling critical needs for assistive listening, translation, and silent disco applications where RF-based systems are not suitable.
