The BERTTI is a distinctive stereo power amplifier from Chord Electronics, built with a substantial input impedance in a remarkably slim chassis. The BERTTI brings Chord's uncompromising engineering to a space-efficient power amplification format.

Key specs that matter

Input sensitivity is 780mV, with input impedance at a substantial 100,000 ohms on both connections. Output power is 75W into 8 ohms. Gain is 30dBu. Frequency response spans 5Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 87dB, with total harmonic distortion plus noise at 0.008% at 100% global feedback. Maximum power consumption is a modest 240W. At a remarkably slim 590 x 235 x 256mm and just 3.75kg, the BERTTI maintains a space-efficient, lightweight power amplifier chassis.

Sound and use context

Expect clean amplification reflecting Chord's broader uncompromising, distinctively engineered philosophy, packed into this remarkably slim, lightweight chassis.

Pairing

Chord's own preamplifier catalogue offers natural, brand-coherent pairings within the same broader catalogue.

Alternatives

Chord's own ULTIMA 6 offers a considerably more powerful alternative within the same broader power amplifier catalogue.
