Page 13: Powering The System
Page 13 of 24 6.0 – Powering the System The EMS-51 can be powered from any amplifier & DSP combinations with the relevant high & low pass filter, and limiter settings. However, due to the self-contained nature of the package, the use of DQ Series advanced system amplifiers is highly recommended. The use of DQ Series amplifiers provides a neat and flexible system that will encompass all requirements for the system to function correctly, as well as providing user control for room EQ and system alignment. -
Page 14: Amplifier Requirements
If not using DQ Series amplifiers, or the DSC48 Digital System Controller, then a suitable DSP system must be used in conjunction with your EMS-51 to prevent damage to the loudspeaker. Check the EM Acoustics website for the most up-to-date DSP settings for the EMS-51. -
Page 15: Presets And Settings
Page 15 of 24 6.2 - Presets and Settings 6.2.1 – Standard EMS-51 Preset When used with a DQ Series amplifier EMS-51 loudspeakers require only a single amplifier channel, and as such the preset recalled will only require one output from your DQ Series amplifier. -
Page 16: Use With The Dq Series Advanced System Amplifiers
Page 16 of 24 6.3 - Use with the DQ Series Advanced System Amplifiers The EMS-51 will perform best when using DQ Series advanced system amplifiers, as not only are they state-of-the-art amplifiers, but the onboard DSP provides appropriate high/low pass filter settings and limiters to get the best from your subwoofers. -
Page 17: System Connectivity
Because pins 2+/2- are linked through inside all EM Acoustics loudspeakers, using a 4-core cable to one loudspeaker (carrying two different signals) allows a crossover cable to be used to link out of the first loudspeaker into another, thereby feeding it from a separate signal. -
