HT 4000 / PT 4000

Description

The AKG PT 4000 bodypack and HT 4000 handheld transmitters have identical transmission characteristics, with a maximum radiated output power of 50 milliwatts. Through special signal companding circuits (compression and expansion), dynamic range capability greater than 120 dB is delivered at the receiver’s output. Audio bandwidth of the system is uniform from 35 Hz to 20 kHz. The

usable distances between the receiver and transmitter can be 100 meters (330 ft) or more. Individual handheld microphone and bodypack transmitters are factory-matched to each receiver. Each system operates on a 30 MHz-wide UHF channel and includes a set of Presets containing Intermodulation Free frequencies as well as a search tuning mode with access to up to 1,200 switchable frequencies. In the U. S., a total of three bands of 30 MHz channels may be selected. The user may expect a maximum of approximately 50 usable channels in a given locale (depending on the local TV channels and wireless frequencies used). In addition to the modulated audio signal, the transmitters send out a data-encrypted PilotTone (at 32,768 Hz) to send important information such as battery status, mute status and more to the system´s receiver.

The HT 4000 handheld and PT 4000 bodypack transmitters can be powered by 2 AA batteries and normal battery life of up to 15 hours can be expected from standard 1.5-volt alkaline cells. An optional BP 4000 rechargeable battery pack is available, featuring Smart Battery Management System Software, and can provide battery life of up to 12 hours plus the remaining battery life can be monitored on the transmitter's & receiver's displays.

Both transmitters come with a backlit display and a jog element for easy setup and full status control. The display features information on selected frequency, gain setting, and remaining battery life in hrs. as well as LOCK and MUTE status. Beside the display and the jog element, the controls on the HT 4000 & PT4000 include lockable ON/OFF button and a separate MUTE switch whose position is easily distinguishable as well as a status indication LED. An inscribable color code facility helps easy channel recognition in multi-channel systems.

The PT 4000 bodypack accepts both microphone and line-level input signals, and the input sensitivity can be adjusted from 0 – 25 dB for optimum gain matching. The antenna is a quarter- wavelength type that affords easy concealment and comfortable wearing. A lockable TA-3FMini-XLR connector is available for easy connection of a broad range of AKG headset, lavalier or instrument mics (e.g. MicroMic Series microphones) as well as instrument cables. The PT 4000 also comes with a 2.5-mm jack connector suitable for the optional RemoteMuteSwitch device RMS 4000.

The HT 4000 handheld transmitter comes with a rugged mechanical solution for interchangeable microphone modules. Six of AKG’s most popular handheld "vocal" microphone head units are available for the handheld transmitter model. The microphones are the dynamic models D 880 WL1, D 3700WL 1, D 3800 WL 1 as well as the condenser models C 900 WL1, C 5900 WL 1, and C 535 WL 1.
