JTS R-4 4 Channel 1RU Wireless Microphone System (638-674MHz)

JP-R4B4 + JP-R4THAB4 x4

This system operates in the 638-674 MHz range thus ensuring that it will operate well into the future. To check if these frequencies will operate in your area please use the ACMA Channel Finder at http://channelfinder.acma.gov.au/. It is also available in the 520-556 MHz range.

The system is designed with JTS's newest generation wireless technology. To cope with the squeezed radio spectrum the system provides more compatible channels within limited bandwidth. The R-4 is a 4 channel system in a single rack unit. Antenna outputs and AC power supply are designed to be cascaded when using more than one receiver, which is very convenient in installations. JTS's patented REMOSET feature sends all microphone data by pushing just one button, and all 4 microphones can receive corresponding data at the same time.

Each belt-pack transmitter comes with a uni-directional CM-501 lapel microphone. Standard R4-TB belt-packs are heavy duty plastic but can be upgraded to the metal R-4TBM belt-pack transmitter for $190 each.

Handheld transmitters can be upgraded to the JSS4A hand-held transmitters with premium JS-22 condenser capsule (silver) for $400 each.
