Introduction
The CA1250 is a major step forw ard in inst allati on a mplifier s technology. Twelve mono Z one power amplifier s, featur ing 85% class D
design technology, can operate as 6 independent Zone amplifiers. Self-explanatory Input and Output connections are easy to follow
since any of the 12 mono amplifiers can be connected to either 70-Volt, 8-Ohm or 4-ohm speaker circu it s.
Each of the 12 mono amplifiers has their own input and output connectors and level Controls. Up to 6 stereo Zones (4-ohm or
70-Volt at 50Watts/channel), 6 mono/bridged Zone amplifiers (110 Watt bridged 8-ohm or 140-Volt). Each zone can be configured
independently allowing a comb ination o f Ster eo 4-ohm or 7 0Volt a nd M ono/Bridg ed 8-oh m o r 140 Volt Zone s. Du al-funct ion LEDs on
the front panel provide bot h ac tivity and Clip in dicatio n for e ach pa ir of a mplifi ers, w hich al so hav e their ow n butto n-selec table L imiter ;
Stereo/Bridge modes and 4-ohm/70V mod es are als o sele cta ble.
The Ch. Input Line/Bus switch selects between either the Bus Input (button depressed) or the individual Zone’s Input signal.
Additional features include: any amplifier with no signal at its input is automatically shut off and the CA1250 is able to operate either
on 110V-120V/60Hz or 220V-240V /50Hz AC mains.
