ATM EPM-700 Stereo

The EPM-700 Stereo consists of two 700 W at 4 Ω class-D Hypex modules with NC500 NCORE technology powered by one 1200 W switched-mode power supply.

The amplifier is assembled entirely by hand in an artisanal way in a uniquely designed anti-vibration monobloc aluminum chassis with individual compartments for the power supply and the power amplifier section, thus avoiding interference between the different circuits. It has an exclusive design and manufacturing input buffer with very low noise operational amplifiers 994 Enh-Ticha from the manufacturer Sonic Imagery Labs and very low noise Sparkoslabs voltage regulators. All connectors are Furutech.

Optionally, the customer can request the inclusion of the following improvements:

• Specific design and manufacturing input buffer with 12AU7 triode valve with very low noise voltage regulators
• Five different colors for the box: black and silver.
