Description

Designed for Effortless Everyday Use

Yamaha

The MA and PA series power amplifiers offer powerful features in compact, durable metal chassis. They are designed for easy, intuitive operation that makes specialized training or audio experience unnecessary. For example, the output volume knob has been made the focus of the front panel design, enhancing day-to-day operability while minimizing the possibility of error. No special software, programming or equipment is required for installation or setup. Anyone can quickly and easily set up a system that will deliver the best possible sound for a wide range of applications.

 

 

Yamaha DSP Features for Enhanced Music and Microphone Operation

Advanced DSP features for background music and paging are efficiently packed into the remarkably compact MA and PA amplifier enclosures. There’s a Feedback Suppressor that can eliminate annoying feedback when using a microphone, a Priority Ducker that smoothly adjusts levels when input is detected at an announcement microphone, a Leveler that maintains constant overall level regardless of changes in input levels and more. The MA2120 additionally features reverb, echo and compressor processing that can be used to enhance the sound and quality of microphone input in a variety of applications.

 

 

Safe and Efficient in Any Environment

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.

 

 

Supports Lo-Z and Hi-Z Speaker Systems

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.

 

 

Flexible EQ Functions

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

 

 

Build a System that Meets Your Needs

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 PA2030a can be added to the system, expanding service areas with volume zoning. A MA2030a system combined with a PA2030a 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.
