I’d like to thank Nathan and the team at Wendy’s Broadcadst for all their help. They have been supplying me with custom cables, made to the highest standard over many year. The low profile connectors are hard to find, yet they normally ship the finished leads the day after ordering, often to studios or locations where I am filming and I’ve never had to ask for any adjustments or corrections; They are right first time, despite my requiring some unusual bespoke wiring. I’ve also benefited from real world advice about products and fault finding. Wendy’s Broadcast have made location sound far less stressful.
The SK 300 G4-RC Bodypack Transmitter from Sennheiser features 3250 UHF frequencies in 25 kHz steps and is built with 20 fixed frequency banks, 32 frequency presets, and 6 user banks with up to 32 user programmable frequencies. It can be used to capture audio when paired with a companion receiver and microphone in various environments for broadcast TV, ENG, and field applications.
The transmitter is menu-driven with a backlit LCD display showing the current frequency, frequency bank, channel number, metering of output level, transmission status, battery status, and more. An auto-lock feature prevents settings from being accidentally altered. The transmitter can be synchronized via an integrated infrared interface and is programmable in the bodypack transmitter menu.
Power is supplied by two 1.5V AA batteries or by a Sennheiser BA 2015 rechargeable accupack. The unit is enclosed in a rugged metal housing and is equipped with a 2.5mm jack to connect a remote mute switch. A 3.5mm jack socket is featured for the mic/line inputs.
