Audison Prima AP4.9 bit - 4 Channel Amplifier

Power Output

• Load Imp. 4 Channels 2 Channels (bridge)
• 4 Ohm 70 W x 4 260 W x 2
• 2 Ohm 130 W x 4

AP4.9 bit amplifier is ideal to realize a powerful two way front full active. The built-in processor, that this amplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs to the AP1 D amplifier, creating a very powerful system in a small space thanks to the “rack mounting” system.

AP4.9 bit amplifier was designed for the Integration into OEM front/rear systems where a lot of power is required. The built-in processor, that this amplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs to the AP1 D amplifier to drive a subwoofer, to the AP4 D amplifier to have 4 additional amplified channels exceeding 1080 W @ 4 - 2 Ω total power.

Accessories

DRC - Digital Remote Control
The DRC is the digital interface between the AP4.9 bit and the user. The DRC mounted in the vehicle dashboard, provides access to control of the inputs and volume adjustments, balance, fader and subwoofer volume. Providing source selection between main, aux and optical inputs, it also provides four of the configurations created and saved by the bit one right at hand. The DRC also controls the functions of the Audison Thesis amplifiers when these are installed in the same system.
