Operating at 72 MHz, the Stationary RF Transmitter Package from Listen Technologies can be used in a variety of assisted-listening applications, broadcasting signal from your particular audio system to a belt-pack or stationary receiver. This model comes pre-packaged with an LA-106 Telescoping Top-Mounted Antenna and an LA-304 Assistive Listening Notification Signage Kit to facilitate communication between you and your audience, whoever they happen to be. With its 80 dB signal-to-noise ratio, it provides intelligible audio across 57 selectable channels, all digitally tuned so that your transmissions won't drift. Up to eight channels can be used simultaneously on the 72 MHz frequency with multiple transmitters.

The transmitter's Look & Listen LCD displays channel, lock, programming, and RF power, while balanced and unbalanced inputs allow you to connect with a variety of audio sources. The transmitter is rack-mountable and features auto-processing to make the audio clearer for audible transmission. To make the unit easier to set up and install, a VU level meter and test tone generator are included.

Q: 5. Can I use a Sennheiser ME II with this if I use an adapter and if so, which adapter?

A: No, the ME 2-II lavalier microphone will not work with the SKP 100 G4 transmitter. The mic requires plug-in power and the SKP 100 plug-on transmitter does not supply any power at all. The Sennheiser SK 100 G4 Wireless Bodypack Transmitter A: 516 to 558 MHz (B&H # SESK100G4A) is the compatible transmitter to use with the ME 2-II. It does have the correct connector for attaching the ME 2-II and also supplies plug-in power for the mic. Just be certain to match the frequency band with your receiver.

A: Yes, the Sennheiser SKP 500 G4 Wireless Plug-On Transmitter (B&H # SESKP500G4AW or B&H # SESKP500G4G1) will supply phantom power to a condenser mic with XLR output. Since you posted your question on the item page for the Sennheiser SKP 100 G4 Plug-On Transmitter for Dynamic Microphones (B&H # SESKP100G4A), please be aware that the SKP 100 does not supply any voltage so it cannot be used for condenser mics and can only be used with dynamic microphones (which do not require any voltage) or condenser microphones that use a battery for power.

Q: 7. Does this fit the new EW-D receiver?

A: The Sennheiser EW-D EM receiver comes with a dedicated rackmount kit for mounting either a single receiver or two receivers together in a standard 19" rack. The GA 4 Rackmount Kit is designed for use with the EM D1 receiver and the dimensions of this receiver are slightly different from those of the EW-D EM receiver. The EM D1 is a bit smaller. At this time Sennheiser does not offer a separate rackmount kit for the EW-D EM since it is included in the box with the receiver. But you can contact Sennheiser directly if you need replacement parts.

Q: 8. Sennheiser EW 100-ENG G2 series and I need to replace the transmitter. Would this G4 version work with the G2 series?
