SZI 1029

IR Audio Transmission Technology Modulators/Radiators

 

When planning and installing an IR system you have to pay attention to use the cor-

 

rect terminating impedance for the radiator chains. Sennheiser IR modulators have

 

an output impedance of approx. 50 Ω, whereas the radiators have a much higher

 

input impedance of > 5 kΩ. This “headroom” allows you to connect many radiators

 

without any problems. In RF transmission, the output impedance has to be termi-

 

nated with approximately the same input impedance. If this is not done, reflections

may occur at the end of the RF chain and disturb the transmission. So, for reasons

 

of reliability, the end of an RF chain should always be provided with a 50-Ω termi-

 

nating impedance. Please note that you should not use “T” adaptors in your RF

 

chain as this would halve the terminating impedance.

 

50 Ω

 

For large installations you should use both RF outputs of the modulator and create

 

two RF chains. This not only increases reliability but also avoids cancelling out

 

between radiators due to time delay. Please refer to the chapter “Planning Theory”

 

for more information on time delay and cancellations.

SZI 1029-10

 

The SZI 1029-10 is Sennheiser’s most powerful radiator. 264 diodes in 24 inde-

 

pendent groups provide an average radiating power of 10 W. The SZI 1029-10 is

connected and operated like the smaller SZI 1029. The radiator’s higher power is a

special asset when it comes to covering large halls or auditoria with high ceilings,

especially when a large number of channels are used.

 

 

The SZI 1029-10 is also interesting for rental companies: due to the higher radiating

 

power less radiators are required and IR systems can be set up and taken down

 

again more quickly. Sennheiser high-power radiators are convection cooled so no

 

cooling fans are used which could cause disturbing noises.

The headphones deliver clear highs, rich mids, and powerful bass, making them suitable for a wide variety of musical genres. This comprehensive sound profile is achieved through meticulous engineering and high-quality materials, which Sennheiser is well-known for in its product lines.

Comfort is a vital characteristic of the SZI series, and Sennheiser has ensured that both models come equipped with ergonomic design features. The choice of soft silicone ear tips in multiple sizes allows users to find the perfect fit, significantly reducing listening fatigue during extended use. This thoughtful design promotes a passive noise isolation experience, enabling users to immerse themselves in their audio without external interruptions.

Furthermore, the SZI 1029 and SZI 1029-10 models incorporate advanced connectivity options. They are designed to provide seamless pairing with a range of devices, enhancing user convenience. Bluetooth technology is leveraged in the SZI 1029-10, which also supports high-quality codecs, ensuring that even wireless listening experiences retain clarity and depth typically associated with wired options.

Durability is another hallmark of these Sennheiser models. Built with robust materials and featuring a tangle-resistant cable (in the case of the SZI 1029), these headphones not only look stylish but can withstand the rigours of daily use. Sennheiser has also included an inline microphone and remote control, allowing for easy management of calls and music playback.

In summary, the Sennheiser SZI 1029 and SZI 1029-10 represent the brand's commitment to sound quality, comfort, and modern technology. With a focus on delivering a superior audio experience, these headphones are suitable for both everyday listeners and dedicated music aficionados. Sennheiser continues to innovate and set the standard in the audio industry, and these models further exemplify their legacy. Whether you're at home or on the go, the SZI series promises an audio experience that is difficult to match.
