The new Audac SMA and SMQ Series of 2- and 4-channel power amplifiers include the new WaveDynamics digital signal processor in combination with a 2.5in LCD display that is claimed to give “an unmatched user experience with intuitive functions overview for easy configuration”.
Acoustics can be optimised using the filters selectable between Low/High & Band Pass and the 7-Band equaliser, which both have adjustable frequencies and Q-factor. Other provided functions are delay (for time-alignment of different speakers) and dynamic bass boost. These settings can be custom-configured using the amplifier’s front panel, whereby access can be given in two different levels (User & Administrator) using password or USB-key protection. Loudspeaker protection is provided by an output power limiter where maximum output power (in watts) for every channel can be configured.
Full system configurations can be selected from a library, which includes loudspeaker performance parameters, and uploaded with a USB drive.
The lightweight Class-D amplifiers are available in 350W, 500W and 750W versions and incorporate: flexible input and output configuration; XLR and terminal block source compatibility; and RS-232 control.
