YAMAHA EMX7|12-input powered mixer with dual 710W Class D amplification
A complete live PA hub for mixing, amplification, effects, and feedback control
The YAMAHA EMX7 Powered Mixer is a 12-input powered mixer from YAMAHA, built around efficient Class D amplification with dual 710W @ 4 ohms output and 8 phantom-powered microphone preamps. It combines a live PA mixer, power amplifier, SPX effects, graphic equalization, and speaker processing in one chassis, making it suitable for performances, lectures, and event sound systems that need fast setup, stable output, and practical control.
Compared with a traditional passive mixer plus external power amp setup, the EMX7 lets users build a working PA system with passive speakers, microphones, and a single power cable. It also keeps essential live tools onboard, including 3-band input EQ, 1-knob compression, 24 SPX effects, a Feedback Suppressor, and a Speaker Processor, so fewer external devices are needed for complete sound management.

YAMAHA EMX7 Core Technologies and Features
-
Dual 710W Class D amplification: The built-in high-efficiency Class D amplifier delivers 2 x 710W @ 4 ohms or 2 x 500W @ 8 ohms, allowing the mixer to drive passive PA speakers directly.
-
12-input live mixing architecture: Connect up to 8 microphones, instruments, or a portable playback device. A hi-Z input also accepts guitar directly.
-
8 phantom-powered mic preamps: The mic preamp layout includes 4 x XLR and 4 x XLR-1/4" combo inputs, supporting both dynamic microphones and condenser microphones that require phantom power.
-
3-band EQ on every input: All 12 inputs include high, mid, and low EQ controls for quick tonal shaping of vocals, instruments, and playback sources.
-
1-knob compression: Inputs 1-4 include Yamaha 1-knob compressors. A single control automatically adjusts threshold, ratio, and output gain to help stabilize vocal or instrument dynamics.
-
24 SPX effects: Built-in effects include reverb, delay, echo, modulation, tremolo, distortion, special effects, and pitch change for performances, presentations, and karaoke.
-
Flex 9-of-31 graphic EQ: The main output includes a 9-band graphic equalizer, with the ability to select up to 9 bands from a total of 31 for adapting to different room acoustics.
-
Speaker Processor and presets: The onboard speaker processor lets users choose a suitable setting for their speakers, with presets tuned for Yamaha CBR, Club, A, and R series passive speakers.
-
Feedback Suppressor: Yamaha digital technology helps suppress live feedback with one-button operation, reducing microphone howling during performances or presentations.
Detailed Functions
-
Simplified PA setup: As a powered mixer, the EMX7 can form a basic PA system with one power cable, passive speakers, and microphones, without requiring a separate power amplifier.
-
Multiple input sources: In addition to microphones and instruments, it supports portable MP3 players. Line inputs include 4 x 1/4", 2 x stereo RCA, and 1 x 1/8" stereo Line for playback, backing tracks, and multimedia sources.
-
Stage monitoring and external routing: It provides 2 x Post aux sends for monitoring or external effects, plus stereo RCA record out and 1/4" main stereo line outputs for recording or system integration.
-
Speaker system matching: Main outputs use 2 x SpeakON-1/4" combo connections, paired with speaker processing, Yamaha passive speaker presets, and Bass Boost for practical PA configuration.
-
Durable chassis and installation flexibility: The robust, impact-resistant, powder-coated metal chassis can be placed on a tabletop, on the floor, or used in installations for long-term stage and event work.
