Frequently Asked Questions



What is the range of the Alto Stealth Wireless receivers?

The wireless signal range replaces wired runs of up to 200 feet from console to receivers eliminating the need for complicated or unsightly cable runs, regardless of the venue. There’s no need to snake, secure, or hide any cabling during set up. After the show, simply disconnect the system and be on your way—no more tedious cable coiling at the end of the night.


Can the Stealth Wireless send a stereo signal?

Absolutely!  Once the transmitter is connected to your mixer or audio source, it can send out a Mono signal to a single speaker or the signal can be split into a stereo signal and sent to individual receivers.  This can happen with just the flip of a switch!  The following diagram shows the standard signal flow of a stereo setup using the Stealth Wireless.

I am not receiving any audio signal.  Why not?

First, ensure that both the transmitter and the receiver are getting power.  Check the power LEDs and make sure that the power adapter is connected correctly.  Next, ensure that both the transmitter and the receiver are set to the same channel.  Also, make sure that the volume controls on your mixer and your speakers are turned up. 


The audio signal is weak or is a poor quality signal. What can I do?

First, make sure that there are no objects (computers, walls, pipes, etc.) between the transmitter and the receivers.  Also, make sure that both the transmitter and the receiver are set to the same channel.

If you are still getting a poor signal, be sure that the receiver antennas are not touching each other and that there are at least 10 feet of separation between the transmitter and the receivers. Make sure that no other devices are sending a signal on the same channel and any other audio cables are away from the antennas.  Try changing the channel that the transmitter and the receiver are on (to the same alternate channel). You can also adjust the squelch control setting. The squelch control setting provides better protection against interference but may also reduce signal range, so keep that in mind as you are adjusting it.


How are the transmitter and the receivers powered?

Each transmitter and receiver comes with its own 12V DC 300mA pin-positive power adapter.


What do I get when I purchase a Stealth Wireless system?

One (1) Stealth Wireless Dual-channel transmitter, two (2) Stealth Wireless Single-channel receivers, three (3) identical 12V, 0.5A pin-positive power supplies, two (2) XLR cables, and all the mounting equipment for each piece.


Can extra receivers be purchased separately?

Absolutely!  Alto Professional also sells the Stealth Wireless Expander pack which comes with two Stealth Wireless single-channel receivers.  With the Stealth Wireless Expander pack, additional receivers can be set to the same channel as the receiver and additional powered speakers can be added.  A standard signal flow using the additional receivers included with the Stealth Wireless Expander Pack is as follows.

How many receivers can be connected to a transmitter simultaneously?

The transmitter is an analog UHF broadcast device.  This means that, in theory, there is no limitation to the number of receivers that can receive the signal.  However, keep in mind that in general, the receivers should be kept a small distance away from each other - typically 1 to 2 feet would be sufficient.


If the Stealth Wireless loses power, will I have to pair the transmitter to the receiver again?

The Stealth Wireless transmitter and receiver will not need to be paired again if power is lost or disconnected. Upon reconnecting the transmitter or receiver to your audio source and output device, the wireless connection will be ready to transmit and receive audio again without any setup. Unlike a wired connection, there will be no noise or popping upon disconnection. Reconnect and power the transmitter or receiver and the devices will automatically connect and be ready for playback.
