Here at Inta-Audio, we're big on big sound.

For many of our customers, getting their homes and workplaces set up with great sound in the most easy and affordable way possible is a big deal. And when it comes to big deals, we have one here that we think you will love...

Introducing the 'SRA-160 Bundle' - Inta-Audio's solution for you which provides you with all that you need for fully-loaded sound at an unbeatable price.


The bundle contains:


   1 x Adastra A2 2x200W Stereo PA Mixer Amplifier (953.402)

   4 x Adastra BC5-B 25” Stereo Speakers – Black (100.905)

   1 x Clarion Series Premium Speaker Cable – 50m (AK-CBL-SC05) 






The A2 is a hi-fi amplifier which is ideal for use in a range of settings, from home installations to schools and small pubs, cafes and restaurants.

Making use of two selectable channels, the A2 allows for independent volume control in two separate locations.

It features two microphone inputs for when you need to reduce the volume of your music to make announcements and a USB slot for playing looping playlists from a USB device without having to physically keep changing tracks at the amp. Inputs can also be connected to the back of the device from CD players, DVD players and VCRs as well as a handy AUX/PHONO port for connecting a wide range of devices such as smartphones and portable MP3 players.

Should you need to connect additional speakers to additional zones, you can also connect the 'LINE OUT' ports of the A2 to the 'AUX/PHONO' port of an additional unit using our inexpensive RCA-to-RCA cable. Combined with another A2, there is the potential to have up to 16 speakers connected at once.

The A2 comes with a remote control in the box and features a built-in FM tuner (antenna not included) allowing for easy and effective radio playback.

It also has Bluetooth built-in allowing you to connect a range of devices, such as a phone or tablet.





Two pairs of Adastra BC5-B are the perfect match for the A2. These popular 8 ohm speakers are the perfect addition to anyone wanting to provide background music in the majority of public/home audio environments. Wherever you are looking to create your setup, the BC5-B speakers require just one simple connection from your amplifier and you are away. 

And because they don’t require 100V Line power, they can be connected to any domestic amplifier via standard speaker cable.

The speakers come supplied with their own mounting brackets, allowing you to either wall mount them or leave them free standing. 







This premium quality transparent speaker cable ensures the very best connection between your amplifier and speakers, bringing a truly detailed sound and quality audio reproduction.
