INTRODUCTION
The AD-9 is the most powerful two channel amplifier within the EM Acoustics range. It has
been designed to meet demands for higher power and increased efficiency, whilst still
maintaining the renowned sonic qualities and unsurpassed reliability associated with our
loudspeaker products.
MC
2
proprietary class-D technology with a dual feedback loop system gives exceptional
transient response and a resonant switch mode power supply with a large reservoir gives
extremely high peak power without any “bass sag”.
Newly designed limiters, linked to the output current monitors and power supply, keep mains
input and output currents within a safe operating area at all times, whilst maintaining
transparent sonic performance.
Running cool in even the most difficult conditions, the AD-9 can deliver over 4500W into 4
ohms with all channels driven, and a massive 16,000W bridged (4R), with outstanding
distortion and noise figures right up to maximum output.
The amplifier, of course, includes full DC, VHF, thermal and short circuit protection to ensure
continuous trouble-free service.
