A400 — Cinema Power Amplifier

The A400 / A600 / A800 / A1200 are four power levels on one amplification platform in Class H with two-channel output, powering the low-frequency and mid/high modules of active-crossover screen channels as well as surround channels and subwoofers. All four share the same connectors, operating modes and protection design, differing only in output power and voltage gain.

The four levels cover 350–1200 W per channel into 8 Ω and 700–2400 W into 4 Ω, or up to 3600 W bridged on a single channel, so a model can be selected directly against a loudspeaker’s nominal impedance and power rating. All four are 360 mm deep, so levels may be mixed within one rack to match each channel’s actual requirement.
