Our compact CA30 100V line amplifier by Adastra is a 30W amp designed for background music or public address. You will also find this amp commonly installed alongside CCTV systems where security horn speakers are fitted to warn off possible intruders.

The CA30 has a built-in mixer with inputs for microphones and a line level input for adding music via a smartphone / iPad / CD or Tuner.

You can control the volume levels via the front panel and at the rear, you can add 1x 8 Ohm speaker (30W max) or a selection of 100V Horn speakers.

An ideal setup would be 2 Horn speakers set to 15W Each to balance the 60W max load. Whilst this is simply an example if you have a specific requirement please contact our technical team.
