The MA/PA Series directly supports low impedance and high impedance speaker systems without the need for additional transformers or other hardware that can take up valuable installation space and increase costs. When used to drive a 3Ω or higher low-impedance speaker system (3Ω/4Ω/8Ω selectable) the MA2030a and PA2030a amplifiers deliver up to 30W per channel into two channels. With a high-impedance 70V or 100V line connection output is a single channel at up to 60W. Likewise, when driving a low-impedance system of 4Ω, the MA2120 and PA2120 amplifiers deliver up to 120W to each of two output channels. When driven at 3Ω/8Ω mode, these amplifiers can deliver up to 100W per channel. With a high-impedance 70V or 100V line connection, a single channel can output up to 200W, which is ideal for powering mid-size installations. In addition, since the MA/PA Series can be used with all Yamaha commercial installation speakers*, you have the choice and flexibility to design a sound system that meets your specific requirements. As indicated, for example, a single unit of MA2120 or PA2120 can support full-range speaker systems at high-impedance mode, as well as a subwoofer at low-impedance mode. With MA2030a or PA2030a which has one output channel, the similar system can be composed by combining two units of amps. * Includes the VXS series, VXC series, VS series, S series, NS-AW series and NS-IC series. The S series, NS-AW series and NS-IC series are not available in some regions.
The MA2030a and MA2120 mixing power amplifiers offer flexible connectivity for a wide range of applications. The MA2030a comes equipped with two microphone inputs (XLR combo jack and Euroblock) and three stereo inputs (RCA pin). The XLR combo jack on the front panel makes setting up for speaking engagements fast and easy. The MA2120 includes six microphone/line inputs (Euroblock) and two stereo inputs (RCA pin, stereo mini phone). All six microphone inputs feature switchable 24V phantom power. Inputs 5 and 6 can also be used as MONO SUM inputs to provide extra input capacity.
