IMPACT OF EXTRANEOUS LIGHT Daylight and artificial light in a room also have an impact on the IR reception. Since the spectrum of this light also contains infra-red portions it can interfere with the useful signal radiated by the SZI 1029. At worst, the reception is disturbed by hissing noise.

COMPUTING THE RADIATING POWER

RULE OF THUMB

During single channel operation (switch set to MONO), every SZI 1029 radiator will supply an area of about 1000 sq.m. The SZI 1029-10 radiators are able to supply approximately double this area.

When switched to narrow-band multi-channel operation (switch set to MULTI) power output and thus irradiated area are reduced by approximately 35 % (see RADIATING POWER DURING MULTICHANNEL OPERATION).

A simple formula facilitates the calculation of the number of radiators necessary to irradiate a given room:

IRlight-Licht

Number of radiators (SZI 1029) =

Grundfläche in m2 x Anzahl der Kanäle surface area in sq. m. x number of channels

650

surface area in sq. m. x number of channels

MULTI-CHANNEL OPERATION an impact on the radiated power of the infra-red radiator SZI 1029. The power is uniformly divided in such a way that, for instance, in a system with 12 narrow-band channels only 1/12 of the desired radiating power is available for each audio channel.

PROPAGATION OF INFRA-RED LIGHT

Number of radiators (SZI 1029-10) =

1300

The high power radiator SZI 1029 radiates the infra-red light in a lobar shape. With increasing distance the intensity becomes weaker. When a receiver leaves the irradiated area the transmission is interrupted. Recei vers without squelch will produce a hissing noise, receivers with squelch will mute.

Sennheiser SZI 1029-10 manual Rule of Thumb, Radiating Power

SZI 1029-10, SZI 1029 specifications

Sennheiser, a renowned leader in audio technology, has made significant strides with its innovative products, including the SZI 1029 and SZI 1029-10 models. These in-ear headphones have been designed to cater to both casual listeners and audiophiles alike, offering exceptional sound quality, comfort, and advanced technology.

At the core of the SZI 1029 and SZI 1029-10 are their premium drivers that ensure a balanced audio experience across all frequencies. 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.
