d&b Audiotechnik A1 Mainframe
Mainframe with two power amplifiers, rated 1200 W and 350 W into 4 Ohms, fitted with appropriate controllers (maximum output power, THD + N < 0,1%)
B1 Option card installed.
The A1 mainframe is housed in a 3 rack unit high, 19″ rack mount enclosure. The A1 incorporates two power amplifiers (1200 W and 400 W), softstart power supplies, monitoring and protection circuits with the associated display elements and all connectors. All functions can be remotely interrogated and altered via the d&b Remote Interface Bridge (RIB). The mainframe accepts a single exchangeable controller module which determines both the type and number of loudspeakers which can be driven. d&b SenseDrive electronics maintain maximum damping factor with complex loads, and improves low frequency transient performance when using long speaker cables. The amplifier is comprehensively protected against overheating, connection to inappropriate or faulty loads, has a high peak output current capability and a low feedback internal gain structure. Speaker ID protects wrongly connected speakers from possible damage.
