YAMAHA AMPLIFIER PA2120

The MA/PA Series packs Yamaha’s decades of commercial audio experience and know-how into compact, powerful, and reliable amplifiers protected by a rugged metal chassis. The MA/PA Series feature interfaces that have been specifically designed for effortless operation. A layout that gives priority to the frequently used output volume knob while other controls are visually subdued, for example, significantly enhances control efficiency in normal day-to-day operation. What’s more, there is no need for computers or complex programming procedures for installation or operation. After a quick, easy setup procedure that requires no special knowledge or skill, the system is ready to deliver outstanding sound in a wide range of applications.

The versatile lineup of the MA/PA Series was developed to cover a diverse range of small to mid-sized installations— often needing only a single model to power the entire sound system. Features that contribute to high quality music playback and microphone use include Feedback Suppressor which effectively eliminates unwanted feedback, Priority Ducker which smoothly adjusts the background program level when a microphone is used for announcements simultaneously, and Leveler, an intelligent algorithm that keeps overall volume constant regardless of changes in source level. In addition, the newly added MA2120 model features an onboard Compressor that adjusts varying mic levels, as well as Reverb and Echo effects for multi-purpose MCing.

The heart of the MA and PA series is a highly efficient Class-D amplifier design that delivers ample output while consuming very little power. It also includes intelligent protection circuitry inherited from Yamaha’s flagship touring amplifier series, effectively protecting both the amplifier and connected speakers. Efficient naturally cooled designs that do not require cooling fans contribute to high reliability as well as quiet operation.

The MA2120 and PA2120 are both certified by ENERGY STAR,* the internationally recognized standard of energy efficiency accorded to environmentally friendly equipment. Both models feature an auto standby function that minimizes power consumption by automatically switching to standby mode when no audio input is detected for more than 25 minutes. Normal operation resumes as soon as audio input is detected. The energy-efficient MA/PA Series amplifiers are also certified as Yamaha Eco Products.**

* ENERGY STAR is a US Environmental Protection Agency (EPA) voluntary program that helps businesses and individuals save money and protect the climate through superior energy efficiency.

**Yamaha Eco Products are part of Yamaha’s voluntary initiative dedicated to environmentally-friendly product development.

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 selectable) the MA2030 and PA2030 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 MA2030 or PA2030 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 MA2030 and MA2120 mixing amplifiers offer flexible connectivity to adapt to a wide range of applications. MA2030 comes equipped with 2 mic inputs (XLR combo jack and Euroblock) and 3 stereo inputs (RCA pin). The XLR combo jack in the front panel makes speaking engagements fast and easy. The MA2120 features 6 mic/line inputs (Euroblock) and 2 stereo inputs (RCA pin, stereo mini phone). All 6 mic inputs feature a 24V setting for phantom power, and inputs 5 and 6 can be also used as 2 MONO SUM inputs, allowing for more input capacity.

The MA2030a features bass and treble stereo source EQ controls. With EQ knobs of MA2030a front panel, the low and high frequency contours of　the stereo input sources can be adjusted. The source EQ also includes an enhancer function* that adds harmonics as necessary for improved sound. With MA2120, an output EQ can be set for each output channel.

In addition, all MA/PA Series amplifiers come equipped with speaker EQ that provides ideal equalization for Yamaha VXS/VXC speakers, LPF** and HPF.

*The MA2120 features the stereo source EQ with an enhancer function for Input 7 - 8, as well as the source EQ for Input 1 - 6. Also, an output EQ can be set for each output channel.

**MA2030a excluded

The MA/PA Series is capable of controlling input sources and volumes for two separate areas (source / volume zoning). For example, in an apparel store with the women’s section downstairs and the men’s section upstairs, or in a restaurant with dinner tables and a bar area, different background music and announcements can be delivered at different volumes to best complement the atmosphere of each environment. Because the MA2120 has two output channels, users can easily manage source/ volume zoning for two separate areas with a unit. (Please refer to System Example 4 and 5.) In addition to volume zoning, the rear-panel ROUTE switches enable input source selection for each area. Speaker output levels in both areas can also be matched via the DIP switch settings. For a larger space, PA2120 or PA2030 can be added to the system, expanding service areas with volume zoning. A MA2030 system combined with a PA2030 can cover two service areas with volume zoning. For example, as shown in the image, background music can be played inside a cafe at a low volume level while the same music plays at a moderate level for an outdoor terrace.

The optional DCP control panels* allow remote volume control, microphone ON/OFF switching, and triggering the built-in chime for announcements.

* DCP4V4S, DCP1V4S and DCP4S, up to two units in total, can be connected to MA2120 and PA2120. One unit of DCP1V4S can be connected to MA2030a.
