30W 3 Input 100V Public Address (PA) Amplifier

A staple of the Redback range since we first started, the 30W amplifier meets the requirements of small to medium public address installations. Features VOX muting, three combined balanced microphone / stereo line inputs, tape out, and separate bass and treble controls. Offers a wide scope of installation applications, including schools, public halls, workshops and sporting complexes. Output may be 100V line or low impedance (8 - 16Ω) speaker loads. This unit features thermal overload shutdown, over current and short circuit protection.

Vox muting: VOX muting is provided on input one, which, when activated, automatically mutes inputs 2 and 3.

Output Muting: An output mute is provided which will mute the output of the amplifier when the Mute Trigger terminals are closed. The output will remain muted while the contacts are closed. This is ideal for emergency override situations.
