Description

The Chord Electronics BerTTi is a compact, fully balanced stereo power amplifier that brings Chord's advanced ULTIMA amplification technology to the Table Top range. Delivering 75 watts per channel into 8Ω, BerTTi combines substantial loudspeaker-driving capability with a compact chassis designed for high-performance systems where space is at a premium.

Built around Chord's latest dual-feed-forward error-correction topology, BerTTi continuously monitors and corrects the signal before the output stage. Balanced XLR and unbalanced RCA inputs, proprietary MOSFET output devices, modified power supplies, and a solid aluminum chassis complete a power amplifier designed to partner naturally with components such as Hugo TT 2.

ULTIMA Amplifier Technology

BerTTi incorporates Chord's next-generation ULTIMA dual-feed-forward error-correction topology, technology derived from the company's larger ULTIMA amplifiers.

The system monitors the audio signal and applies correction before the output stage, helping maintain signal accuracy as the amplifier drives connected loudspeakers. BerTTi also uses Chord's custom-made MOSFET output devices and a high-frequency switch-mode power supply.

75 Watts Per Channel

Despite its compact Table Top chassis, BerTTi delivers 75 W per channel into 8Ω.

Its power architecture incorporates two modified power supplies, along with an additional auxiliary power rail for the front end. This provides additional voltage for driving Chord's proprietary MOSFET output devices and supports the amplifier's ability to handle dynamic musical demands.

Balanced & Unbalanced Connectivity

BerTTi provides both balanced XLR and unbalanced RCA stereo inputs, making it easy to integrate with a variety of compatible preamplifiers and source components with variable analog output.

Gold-plated loudspeaker terminals provide the connection to your speakers, while the amplifier's fully balanced architecture makes the balanced XLR connection a natural choice when used with suitably equipped components.

Designed for Hugo TT 2

BerTTi is a natural amplification partner for the Chord Electronics Hugo TT 2, which can provide DAC and preamplifier functionality while BerTTi handles loudspeaker amplification.

Adding the Hugo M Scaler creates Chord's compact three-component Table Top digital system: M Scaler for digital upscaling, Hugo TT 2 for digital-to-analog conversion and preamplification, and BerTTi for stereo power amplification.

Compact Table Top Construction

BerTTi measures just 59 × 235 × 256 mm and weighs 3.75 kg, allowing serious stereo amplification to fit into a relatively compact system.

The amplifier is housed in a solid aluminum chassis and is designed, engineered, and handmade in England.

Frequently Asked Questions

What is Chord Electronics BerTTi?

BerTTi is a compact, fully balanced stereo power amplifier from Chord's Table Top range. It incorporates ULTIMA dual-feed-forward technology and delivers 75 W per channel into 8Ω.

How much power does BerTTi deliver?

BerTTi delivers 75 watts per channel into 8Ω, according to Chord's V1.1 manual and official product literature.

What is Chord's ULTIMA technology?

ULTIMA uses Chord's dual-feed-forward error-correction topology, which monitors and corrects the signal before the output stage. BerTTi combines this technology with proprietary MOSFET output devices and Chord's power-supply architecture.

Does BerTTi have balanced inputs?

Yes. BerTTi provides one stereo pair of balanced XLR inputs and one stereo pair of unbalanced RCA inputs.

Does BerTTi have a built-in preamplifier or volume control?

No. BerTTi is a dedicated stereo power amplifier. It should be paired with an appropriate preamplifier or compatible component providing volume control, such as Hugo TT 2.

Can BerTTi be used with Hugo TT 2?

Yes. Chord specifically positions BerTTi and Hugo TT 2 as system partners. Hugo TT 2 can provide DAC and preamplifier functionality while BerTTi powers the loudspeakers.

Can BerTTi be used with Hugo M Scaler?

Yes. A complete Chord Table Top system can combine Hugo M Scaler + Hugo TT 2 + BerTTi. M Scaler handles digital upscaling, Hugo TT 2 performs DAC/preamp duties, and BerTTi provides speaker amplification.

Is BerTTi a Class D amplifier?

No. Independent Chord-hosted technical reviews describe BerTTi as a Class AB MOSFET power amplifier, rather than Class D. Chord's core product page itself emphasizes its proprietary MOSFET architecture and ULTIMA topology.
