Étude has no ability to switch between the inputs, therefore, only one must be used.
4.1 4.2 Placement Connecting Étude to ancillary equipment 4.3 Line level inputs Chord Electronics Étude | Manual _ Audio outputs 4.4 Étude supports a single stereo output. In order to connect Étude to loudspeakers, use high-quality loudspeaker cable terminated with 4mm banana plugs or 6mm spades. Bare wire can be used, but it is not recommended.
4.1 4.2 Placement Connecting Étude to ancillary equipment 4.3 Line level inputs Chord Electronics Étude | Manual _ Power-on sequence With the unit connected to a mains power supply, switch Étude ‘on’ using the analogue rocker switch located next to the mains input. This will switch the unit both on and off. During the initial start-up phase, Étude will power-up and perform a safety check.
4.1 4.2 Placement Connecting Étude to ancillary equipment 4.3 Line level inputs Chord Electronics Étude | Manual _ Earthing issues in Europe In some European countries, a hum or buzz may occur if the amplifier is connected to mains sockets that do not have an earth or adequate earth. If this occurs, please ensure that your equipment is connected via a good-quality multi-way mains block which contains an earth point at every socket outlet.

5.1 Chord Electronics Étude | Manual _ Bridged operation & set-up Although the amplifier is conservatively rated at 150W into 4Ω, Étude can be operated in bridged mono mode, increasing power to 300W into 4Ω. The bridged mono configuration allows two separate Étude power amplifiers to be used in a system, each feeding a separate loudspeaker. In this manner, each power amplifier only carries the signal for the left or right channel of audio.
