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 A4 Hi-Fi Amplifier (953.404)
•    8 x 6.5" 8ohm ceiling speakers (B421A)
•    1 x AudioKraft 100m 2x 0.75mm 18AWG Multi-Strand Loud Speaker Cable/Wire

The Adastra A4 4-Channel 4x 200W Hi-Fi Amplifier:

The A4 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 zones and 4 channels, the A4 allows for independent volume control in 4 separate locations, as well as independent source selection across channels 1 & 2 simultaneously, and 3 & 4 simultaneously.

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 A4 to the 'AUX/PHONO' port of an additional unit using our inexpensive RCA-to-RCA cable. Combined with another A4, there is the potential to have up to 16 speakers connected at once.

The A4 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.

The bundle includes a set of 8x standard 6.5" (inch) 8ohm directional ceiling speakers with adjustable tweeters which can be angled to the desired direction that you wish the sound to be directed to.

Fitted with "dog-leg" mounts for a quick and easy installation, these simple yet reliable speakers have a Max RMS Power of 50W and come with a standard domestic speaker cable included in the box.
