The Sigtronics music switcher is fully compatible with music systems that have line level output, headphone level (Walkman) output, or speaker output up to 25 watts per channel. No additional amplifiers, adapters or modifications to the RES-2 unit are required. The Sigtronics RES-2 system is designed for use with general aviation Stereo headsets with high impedance speakers (200 to 600 ohms).
Several modes of operation are possible. The pilot can listen to music and be switched automatically to the VHF when incoming transmissions occur, or may elect to remain on the VHF only (Pilot Isolate) and not listen to the music. The pilot also has the option of putting the passengers on uninterrupted music or letting the VHF interrupt their music so they may hear the radio communications.
The RES-2 comes complete with pre-wired harness, stereo headphone jacks, wires and carries a 5 year warranty. The RES-2, like all Sigtronics products, is RFI and EMI free, and does not require shielded cable. The RES-2 weights only 11 ounces with cables and accessories, and is a compact 4 x 2.9 x 2 in size.
