Legacy Series - AP312
The AP312 includes the same great features as the AP812 but with a little less power at 320 Watts (160 Watts/ch @ 8 ohms). The AP312 power amplifiers have been specially optimized to deliver full power into 8 Ohm loads, the most common speaker impedance. Internal Silentfan™ cooling provides whisper-quiet performance. Channels 9 to 12 are configured in stereo with cueing switches and RCA inputs for disc jockey and/or live theater applications.
Features
Channels 9 to 12 are configured in stereo with cueing switches and RCA inputs for disc jockey and/or live theater applications. Patching is easily accomplished with top-mounted jacks and includes switchable mains / monitor amp assignment along with plenty of inputs and outputs for external audio processing.
Rear mounted 1/4" phone jacks are provided for easy speaker output. Other features include: Two assignable 9-band graphic equalizers, a 255-preset digital effects processor with footswitchable in/out, phantom power, effects return fader, headphone jack, two LED VU meters rubber-surround rotary knobs, smooth faders and an optional 19" rackmount kit.
