The EW 135 G3 system includes the EM 100 G3 rack-mount receiver and the SKM 100 G3 microphone/transmitter. The microphone features Sennheiser's famed e835 cardioid dynamic capsule. The transmitter runs for up to eight hours on two AA batteries, and also operates with the BA 2015 rechargeable battery pack. You can recharge the battery pack while it's in the transmitter using Sennheiser's L 2015 charger (battery pack and charger sold separately). Four-stage battery indicators monitor your battery's charge level.

The receiver scans automatically for available frequencies and syncs with the transmitter automatically via an infrared interface. The receiver's true diversity reception gives you a dependable connection with the transmitter. The frequency bank system offers 12 compatible frequencies per bank for simple matching.

The transmitter and receiver are both housed in rugged metal cases to shield them from the bumps of life on stage. You'll have no problem setting up and using this system, thanks to the user-friendly operating menus on the transmitter and receiver.

Overview: The Sennheiser EW 135 G3 is a wireless vocal microphone system, featuring the e 835 handheld dynamic cardioid microphone with the SKM 100 wireless transmitter inserted, and EM 100 G3 True Diversity receiver. It is designed for every style of music, and its rugged metal housing helps it withstand the rigors of a live performance. The system features a 42 MHz bandwidth; this system operates on frequency range A (516-558 MHz).

Wireless System: The EW 135 G3 evolution system feature high-quality true diversity reception with dual antennas. The automatic frequency scan feature searches for available frequencies for interference free operation. The system supports up to 12 channels. The Sennheiser HDX compander system assures crystal-clear sound.

Microphone: The e 835 is a cardioid dynamic microphone, designed to be used as a vocal stage mic. It can handle high sound pressure levels up to a maximum of 154 dB SPL. It's cardioid polar pattern is sensitive to sounds directly in front of the element, and provides excellent rejection of off-axis sounds and feedback. The e 835 comes with the MZQ-1 swivel mic stand mount that screws onto any microphone stand with 5/8" or 3/8" threads (using the included thread adapter).

Wireless Transmitter: The SKM 100 wireless transmitter is mounted inside of the e 835 microphone. It is powered by 2 "AA" batteries (included), which give it approximately 8 hours of battery life. The transmitter's 3-line illuminated display will indicate the current transmitting frequency, the customizable name of the mic, transmission and lock mode icons, and mute status. It shows a 4-segment battery status: 3 bars-100%, 2 bars-70%, 1 bar-30%, 0 bars-Low battery. The transmitter has an On/Off button, and a multi-function switch to set the transmitting channel. A rotating cover protects the multi-function switch from accidental operations.

Wireless Receiver: The EM 100 G3 True-Diversity wireless receiver can be placed on a flat surface, rack mounted, or stacked with other receivers using the included stacking elements. The illuminated front panel display clearly indicates the current frequency, frequency bank, and channel number. It also displays the battery status of the transmitter, as well as the RF levels (how strong the wireless signal is) and Audio levels (how loud the audio signal is). Like the transmitter, the name of the receiver is customizable. The two diversity antennas plug into the BNC connectors on the back panel. The receiver is powered by the included 12-volt DC power supply.

EQ Presets: The system has four EQ presets that can be recalled. Preset 1: Flat; Preset 2: Low Cut (-3 dB at 180Hz); Preset 3: Low Cut/High Boost (-3dB at 180Hz / +6dB at 10kHz), Preset 4: High Boost (+6dB at 10kHz). These presets affect the line and monitor outputs.
