SA20:2 High performances class D amplifier 2 bridgeable channels 2 x 1950 W in 4 Q Features High audio quality Performance and power efficiency Protection circuits for reliability Control software Applications High quality sound reproduction Mid to high power amplification Medium to large scale APG systems Specifications Universal switch mode power supply with PFC (Power Factor Correction) EIAJ Test Standard, 1 kHz, 1% THD Power efficiency >85% Fixed switch frequency RS485 serial communication port Optional Ethernet/AES3 interface The SA20:2 is a 2 channel fixed switching frequency class D power amplifier. Two bridgeable channels allow all sorts of configurations of cabling depending on speakers and impedance load. Precise gain and sensitivity setting is obtained via internal digital gain control. The SA20:2 delivers high power and sonic quality thanks to a careful design of all its components. The state-of-the-art switch-mode power technology allows high output power with superior efficiency. The SA20:2 has a very high level of reliability thanks to its numerous protections against clipping and high voltages or current. Its functional parameters, mains voltage and current draw, are monitored and saved. The temperature is carefully controlled by variable-speed forced-air cooling. The SA20:2 is lighter than most amplifiers and fits in only one rack unit to ease transport and handling. The device can be configured via its front panel LCD screen, and via PC connexion thanks to its RS485 port. The SA20:2 is a 2-channel amplifier for mid to high power applications. It uses the same internal technology than the SA30:2 and offers compatible performance, but it is less powerful. Its characteristics are high dynamic and power capacities, combined with a sturdy and ergonomic design that perfectly meets the requirements of live events and shows, in fixed installation as well as in touring. Thanks to its performance in terms of power, it naturally suits APG speaker series Micro, Dispersion, Sector and Beam. Although the SA20:2 amplifier is optimized for a 4 to 8 Q load, operation under 2 Q load is possible, provided there is a sufficient headroom. The bridged mode allows high-voltage operation into 4 to 16 Q loads. The SA20:2 must be used according to APG-recommended combinations of speakers and processors.
