AKG HT450/D5
Frequency-agile UHF handheld transmitter with AKG D5 dynamic microphone capsule.
Uses infrared data link for programming.
The HT 450 is a high-performance, rugged handheld transmitter for a host of applications. Many innovative features enhance both system reliability and user friendliness.
An LC display indicates all important system data at a glance, including the selected frequency in MHz or as a Preset subchannel, available battery capacity in hours, a warning when battery capacity is low, as well as the current transmission mode.
Once you have set a frequency on the receiver, an infrared transmission link will feed the related data to the assigned transmitter within seconds, making the setting up of large multichannel systems child's play.
The HT 450 handheld transmitter is available with the dynamic microphone element D 5 or the condenser microphone element C 5.
A noiseless ON-MUTE/PRG-OFF switch and status LED add to the transmitter's user-friendliness.
