Classe Delta Stereo Amplifier black

When there is not enough space for two mono amplifiers, the Delta STEREO is the solution for performance without compromise.

The highlights at a glance

• Up to 35 watts (MONO) or 12.5 watts per channel (STEREO) in pure Class A operation and control with
  low impedance eliminate switching distortions at low signal levels and guarantee a sovereign
  performance with any type of speaker.
• The in-house ICTunnel™ technology for active cooling ensures an ideal operating temperature for
  maximum performance and reliability even under maximum loads.
• Special and premium components such as the 22 four-pole capacitors from Mundorf®, the custom-made
  Toroidal transformer and hand-built 4- or 6-layer printed circuit boards ensure excellent performance.
• Furutech® rhodium-plated RCA and Torque Guard speaker terminals offer greater durability and performance than gold terminals.
• Navcom® custom feet dampen vibration and counteract microphonic effects, improving overall clarity.
• Level meters provide diagnostic feedback as well as an aesthetic visual representation of the auditory and
  noticeable performance.

The first 12.5 watts of power fully correspond to the Class A amplifier class. With a total of 250 watts per channel (more than 350 watts per channel at 2 ohms), the compact, powerful amplifier supplies every speaker in an impressively sovereign way.

• Up to 12.5 watts per channel in pure Class A operation
• A total of 250 watts per channel
• Stable, high-quality power supply
• Custom made toroidal transformer

design

Strong appearance: The design of the Delta STEREO is an expression of its performance. It looks fantastic in any setting and facility.

Exquisite finishes and two custom-designed illuminated meters make the power output display for both channels eye-catching.

The design concept of the Delta Series is to create a monument to sound. And the amp looks just as powerful as it sounds.
