AirX-RearKit HiRes Audio Wireless System with Amplifier for passive (Surround) Speakers in a 5.1 Home Cinema
Connect and forget - as reliable as a cable!
Home cinema without cables - connect your passive surround speakers wirelessly to any AV receiver via the VOCOMO AirX audio radio system!
No annoying cables to lay across the room - a socket is enough: Complete kit for wireless connection of passive speakers with any AV receiver.
Features
- System for wireless HiRes audio transmission to 2 passive loudspeakers
- Uncompressed digital signal transmission (lossless)
- 1x Transmitter with pre-amplifier and speaker inputs (integrated high-low converter)
- 2x Receiver with integrated 36W Class-D amplifier in high-end sound quality
- Minimal end-to-end delay (19ms), automatically compensated by all common AV receiver calibration systems
- Stable 2.4GHz radio transmission with external antennas and adaptive frequency hopping
- "Always-on" capability thanks to automatic standby with minimal power consumption
- Channel (left / right) selectable on the receiver
- Status LED that can be switched off
- Easy installation of the receiver on the loudspeaker (Velcro points) - removable
- Scalable system: Several transmitters can be cascaded (master-slave) *)
*) A "master" transmitter can be supplemented by one or more "slave" transmitters. All transmitters are synchronized (interconnected) via a special USB Y-cable, which is included with the "slave" transmitters. Always choose a "master" transmitter for your first AirX system, and a "slave" transmitter for adding to an existing AirX system!
Use Cases
- 5.1 / 7.1 home theater systems: ideal for the wireless integration of passive surround speakers
- Multiroom systems
- Wireless hi-fi systems
FAQ
| Q: |
Can't I just connect the speakers in my home theater via Bluetooth or WiFi? |
| A: |
No. In home cinema it is particularly important that the sound is reproduced synchronously from all channels and lip-synchronously with the picture. The delay time of Bluetooth and WLAN (200-300ms) is much too high and should be less than 20ms for home theater systems. |
| |
|
| Q: |
What is the range and how stable is the radio transmission? |
| A: |
VOCOMO AirX radio systems transmit in the 2.4 GHz band with external antennas and thus penetrate walls and other obstacles better than systems in the 5 GHz band. The range is up to 100m outdoors and 20m indoors, with walls / ceilings in between. Thanks to a self-learning, adaptive frequency hopping process, the transmission automatically optimizes itself to the radio environment and transmits in the best available channels. |
| |
|
| Q: |
How does the calibration system of my AV receiver deal with surround speakers connected via AirX? |
| A: |
If your AV receiver has an automatic calibration system, we recommend using this with a VOCOMO AirX radio system! For the calibration system, it does not matter whether the loudspeakers are connected by cable or AirX. However, if loudspeakers that have previously been connected to the AirX by cable are connected, the calibration must be carried out again.
If your AV receiver does not have a calibration system, add 6.5m to the physical distance of the AirX speakers and adjust the levels as described in the instructions for the AV receiver. |
| |
|
| Q: |
Can I really connect an AirX system to any AV receiver, even if it has no preamp outputs? |
| A: |
Yes. In contrast to many other products, VOCOMO AirX transmitters have inputs for pre-amplifier signals as well as the option of receiving signals directly from the loudspeaker output of your AV receiver. |
| |
|
| Q: |
How do I switch the AirX transmitter and receiver on or off? |
| A: |
VOCOMO AirX transmitters and receivers are optimized for minimal power consumption. If no signal is reproduced, the devices automatically switch to standby mode with a power consumption of <0.4W. All AirX devices can therefore remain switched on permanently. Transmitters can optionally be switched on / off automatically by the AV receiver, e.g. via a USB socket of the AV receiver or a trigger switch socket. |
