CHORD ELECTRONICS PRESENTS THE NEXT-GEN STEREO POWER AMPLIFIER EQUIPPED WITH A NEW TOPOLOGY - THE ÉTUDE

Welcome to the table, Étude, a 150w Class AB dual power amplifier with the company's first novel topology since its inception in 1989. The Étude is the brainchild of Chord Electronics' Owner, John Franks. Chord Electronics' multi-award-winning Choral line of products has never sounded better. With faster power delivery, the Choral Étude complements its full potential with Unrivaled dynamics, true-to-life transient representation, and simple control over driving loudspeaker components.

ERROR-CORRECTION AMPLIFICATION TECHNOLOGY FUSED WITH SWITCH-MODE POWER SUPPLY

From the get-go, Chord Electronics’ amplifiers pushed the technology envelope producing amplifiers with switch-mode power supplies (SMPS). The multi-feedback and dual feed-forward error-correction amplifier technology used in Étude automatically adjusts and compensates the individual linearity of the 250-watt lateral structure high-power proprietary MOSFETs. There are three separate high-frequency switch-mode power supply units for each active power rail and the auxiliary rails. Étude is a fast amplifier with superior internal shielding, actively cooled plenum chamber design and Chord Electronics MOSFETs. Although the amplifier delivers the power of 150W into 4, it can be increased to 300W into 4 using Étude in bridged mono mode. Étude powers in mute for a few seconds before switching to play mode with a gentle click of a relay, this effectively serves as a quiet start and power-down. This process is carried out without clicks, pops, or thumps from the speakers when powering on the Étude.

A CLASS-LEADING PERFORMANCE WITH VARIOUS CONNECTIVITY AND EXPANSION OPTIONS

The Étude amplifier skillfully integrates elements of Chord Electronics' traditional amplifier designs with its personality, and the two meld perfectly. There are both balanced XLR and single-ended RCA inputs on the back panel. The lone power button is next to the IEC power input, and the only indication lights are the blue LEDs on the circuit board, which are visible via the vent holes on the front and top right-hand sides of the Étude.

ECCENTRIC FEATURES AND TECHNICAL SPECIFICATIONS PRESENT LUSH AUDIO

The Chord Electronics sound is about balanced detail that delivers an intriguing listening experience. Étude also excels in the speed and pace of the presentation. Chord Electronics' characteristic precision and clarity of tone, dynamics, and detail are combined in a single package in Étude. It comprises key features like Class AB Sliding Bias, HF Switch Mode Power Supply, Chord MOSFET, Fully Balanced Circuitry, Fan Cooling, Stereo Balanced XLR Inputs, Stereo Unbalanced RCA Inputs, and Bridging capability of 300w with 4 Ohms of impedance. Étude delivers an Output Power of 150w RMS per channel @ 0.05% distortion into 4Ω and a Frequency Range of 5Hz – 100kHz +/- 0.5dB. It has an Input Impedance of 100kΩ unbalanced/Balanced.

BRANDISHES A CLASS-LEADING BUILD QUALITY

Chord Electronics is known for its elegant build quality Étude comes as no surprise with its solid block of aircraft-grade aluminum chassis that gives it a premium look and feel.
