4-channel amplifier

The AP-4340 4-channel class AB amplifier can be used in three modes: 4, 3 or 2-channel.

In 4-channel mode, its CEA power of 4 x 70W RMS will allow you to get the most from your Auditor kits installed up front and in the rear. The 3-channel mode enables you connect a kit to channels one and two, as well as an Auditor subwoofer to channels three and four in bridged mode for a CEA power of 190W RMS under 2 Ohms. The 2-channel mode, which consists of bridging channels 1-2 and 3-4, provides a CEA power of 2 x 190W RMS under 2 Ohms.

Equipped with high-pass and low-pass crossovers, as well as a subsonic crossover, the AP-4340 amplifier guarantees the optimal performance of the kits and subwoofers in this line.
