Audio Ltd Envoy plug-in Transmitter for Envoy radio mics (PTX)

The PTX is a compact, fully featured transmitter designed to connect neatly to any dynamic or condenser microphone equipped with a standard balanced XLR and turn it into a wireless handheld microphone. Connection is via an industry standard Neutrik three pin XLR and an integral locking ring ensures that the connection is always secure.

The PTX is designed in a unique trilobular shape which means, on camera, it will look compatible with modern slimline mics. Its low weight and profile also make it ideal for use with a boom pole or as part of a discreet microphone set up which needs to be hidden on set. There is no trailing antenna either – the PTX’s antenna is built into its robust aluminium body.

It can be supplied with up to 80 MHz switching bandwidth (the equivalent of 10 TV channels in Europe and 13 TV channels in the US) and programmable with up to 10 frequency tables – giving it enormous flexibility anywhere in the world. There are two output power settings – low (25mW) and high (50mW) – ensuring a continuously good RF link with any En2 receiver while in use.
The PTX is fully compatible with both CX2 slot-in camera receivers and with all other receivers in the En2 range.
