A. Main function of amplifier
1. 2-channel, parallel or bridged, mono operating modes for flexible application.
2. Independent limiters for each channel offer dependable protection against distortion.
3. Precise signal and clip LED indicators to monitor performance.
4. High-current toroidal transformer for absolute reliability and lowest noise emission.
5. Independent DC and thermal overheat protection one each channel automatically protects
amplifier and speakers.
6. “Back-to front” ventilation system including air filler will automatically adjust fan speed for
smooth operation.
7. Balanced XLR and 1/4” TRS inputs.
8. Professional connectors compatible to speakon and “touch –proof” binding post
loudspeaker outputs enable secure operation.

Protect LED: Indicates that the channel is in protecting mode (speakers disconnected by
output relay).
⑥
Signal LED: Illuminates to indicate that a signal (above a minimum threshold) is present
at the amplifier in put and that the signal is being amplified.
⑦
Clip LED: Illuminates at the clipping threshold. Continuous illumination also indicates that
ACL (Active clip limiting) protection circuitry is engaged.
