Alto Stealth Wireless MKII

The Alto Stealth Wireless MKII system makes it easy to add wireless audio connectivity to any active speaker without compromising audio quality.

The system works through walls, floors and ceilings, offering setup flexibility that significantly outperforms conventional wired systems and provides a range of up to 61 meters.

The system includes one dual-channel transmitter with two detachable antennas. The front LCD screen displays useful information such as RF frequency, channel number and AF signal level for each channel. Each system also includes two receivers with low-profile, rugged plastic housings and dual swivel and retractable antennas.

Stealth Wireless MKII can be set to mono or stereo operation. Two XLR & balanced 6.35mm TRS combination inputs on the transmitter allow connection to the main outputs of virtually any mixer or console.

Each receiver unit has a single 6.35mm TRS output to send the signal to an active speaker group or to a traditional amplifier and speaker combination. Also included are 2x 6.35mm TRS-to-XLR cables so you can connect your system right out of the box.
