Yamaha EMX7- Dual 710 Watt 12 Channel Stereo Powered Mixer with 24 SPX Effects

The Yamaha EMX7 is a powerful and highly capable 12-channel stereo powered mixer that builds upon the success of Yamaha's long line of reliable powered mixers. It's designed for musicians, bands, public speakers, and mobile DJs who need a robust, all-in-one sound reinforcement solution with significant power and advanced features.

Here's a detailed look at its key features and specifications:

Power and Amplification:

• Dual 710W (1420W total) Class-D Amplifier: The EMX7 features a high-efficiency Class-D power amplifier.

  • It delivers 710W + 710W into 4 ohms (at 1kHz, THD+N < 10%, CEA2006 rating) for a total dynamic power of 1420 watts.

  • For a cleaner, continuous output, it provides 600W + 600W into 4 ohms (at 1kHz, THD+N < 1%, CEA2006 rating).

  • Into 8-ohm speakers, it provides 500W + 500W (THD+N < 10%) or 400W + 400W (THD+N < 1%).

• High Efficiency & Lightweight: The Class-D design contributes to its impressive power output while keeping the unit relatively lightweight (approx. 9.5 kg / 20.9 lbs) and energy-efficient.

• Protection Circuitry: Features comprehensive overload protection functions (overheat, overcurrent, DC-fault) to ensure reliable operation and extend the life of the components.

Mixing Channels & Inputs:

• 12 Input Channels: A versatile array of inputs to handle various sources:

  • 8 Mono Mic/Line Channels:

    • Channels 1-4 feature combo XLR/1/4" jacks with switchable 30dB PADs for high-output sources.

    • Channels 5-8 feature XLR inputs and separate 1/4" inputs.

  • 4 Stereo Line Channels:

    • Channels 5/6 and 7/8 also include 1/4" TRS inputs for stereo line-level devices.

    • Channels 9/10 include XLR, 1/4" TRS, and RCA stereo inputs.

    • Channels 11/12 include XLR, RCA, and a 3.5mm stereo mini-jack input for connecting portable music players like smartphones or laptops.

• Hi-Z Input (Channel 4): A dedicated Hi-Z switch on channel 4 allows direct connection of high-impedance instruments such as electric guitars or basses without needing a separate DI box.

• 48V Phantom Power: Available on all 8 XLR microphone inputs to power condenser microphones.

• High-Pass Filters (Channels 1-3): 80 Hz, -12 dB/octave HPF to reduce unwanted low-frequency rumble, hum, or proximity effect from microphones.

EQ and Dynamics:

• 3-Band EQ per Channel: Each of the 12 input channels has independent High (10kHz shelving), Mid (2.5kHz peaking), and Low (100Hz shelving) EQ controls for shaping individual instrument and vocal tones.

• 1-Knob Compressor (Channels 1-4): Yamaha's popular and intuitive 1-knob compressor on the first four channels simplifies dynamics control for vocals and instruments. Turning a single knob adjusts multiple compression parameters (threshold, ratio, and output gain) simultaneously for optimal results.

• Flex 9 Graphic Equalizer (Flex9GEQ): This is a standout feature unique to the EMX7 (compared to the EMX5's simpler Master EQ). It allows you to select up to nine bands out of a total of 31 standard ISO frequencies and adjust their gain by 15 dB. This provides precise control over the overall mix to optimize the sound for different room acoustics or speaker characteristics, similar to what you'd find on higher-end consoles.

• Speaker Processor Function: The EMX7 includes a speaker processor that allows you to select specific presets tuned for Yamaha's passive speaker models (like CBR, Club, A, and R series). This optimizes speaker performance and includes a bass boost function for enhanced low frequencies.

Effects and DSP:

• Yamaha SPX Digital Effects: Features a powerful DSP section with a total of 24 different high-quality SPX effects, including various reverbs (hall, plate, room, stage), delays (echo, vocal echo), chorus, flanger, phaser, tremolo, pitch change, and distortion. Effects can be applied to individual channels via aux sends.

• Feedback Suppressor: Utilizes Yamaha's unique digital technology to automatically detect and eliminate unwanted feedback with the simple push of a button. It employs a 7-band notch filter for effective feedback control.

• Aux Sends: Two Aux sends are available:

  • Aux 1 Send: Can be used for a dedicated monitor mix or external effects.

  • Aux 2 Send: Primarily for the internal SPX effects processing, but can also be used for monitoring.

Outputs and Monitoring:

• Speaker Outputs: Two speakON/1/4" combo jacks for connecting passive loudspeakers (Channels A & B).

• Stereo Out (Line Level): Balanced 1/4" TRS outputs for connecting to external powered speakers, an additional power amplifier, or an external recorder.

• Rec Out (RCA): Unbalanced stereo RCA outputs for connecting to a recording device.

• Footswitch Input: Allows for remote control of the effects mute on/off.

Design & Portability:

• Robust & Portable Design: Features a rugged, impact-resistant, powder-coated metal chassis designed for extended operation and road use.

• Integrated Handles: Large handles on the front and back of the enclosure make it easy to transport and help protect knobs and terminals from impact during handling.

• Versatile Placement: Can be used on a tabletop, on the floor as a wedge, or rack-mounted with an optional kit (RK-EMX7).

• Universal Power Supply: Operates on 100-240V AC, 50/60 Hz, ensuring worry-free operation worldwide.

The Yamaha EMX7 is a highly capable and user-friendly powered mixer, offering a significant amount of power, a comprehensive set of inputs, powerful DSP features (especially the Flex9GEQ and Speaker Processor presets), and renowned Yamaha reliability. It's an excellent choice for demanding live sound applications where a compact, all-in-one solution is preferred.
