Product Description

The Beyerdynamic A20 headphone amplifier is designed to get the best sound from a range of headphones (models with a nominal impedance between 30 to 600 ohms). Considering its design and sound quality, the A20 offers incredible value for money.

Two Headphone Outputs

Unlike many headphone amps, the A20 includes 2 headphone outputs, so you can A/B compare your headphones and/or plug in two pairs to enjoy listening with someone else at the same time.

Ease of Connection Options

The A20 is designed for purity of sound, yet its also very conveniently designed, with both RCA input and output on the back, allowing you to connect it inbetween your source and amplifier (if you're using it with a main hi-fi system), so you can use it without needing to unplug your source every time.

Alternatively of course, you can connect it directly to the "Pre Out" on your amplifier to listen to whatever source is selected on your main amplifier.

Sound Quality

The power amplifier, of a discrete design, and the combination of selected high-grade components inside the device allows even high-impedance hi-fi headphones to be driven flawlessly over the entire frequency range.

The A20 supplies an impressively natural and transparent sound with excellent resolution and spatiality. The volume control adjusts the volume for both headphone outputs, which are connected in parallel. Its handbutton is made of solid aluminium and hides a high-grade ALPS potentiometer with smooth volume values.

Build Quality

Gold-plated RCA phono sockets on the rear are used to connect the audio source and allow a signal transmission without loss. The input is looped-through, which means audio signals that are present at the INPUT sockets are routed to the OUTPUT sockets, even when the device is switched off. Due to the hard-wired design there is no loss.

The high-quality metal housing is made of brushed aluminium and protects against signal scattering and vibration. Due to the internal wide-range power supply the A 20 can be operated with 110 V/60 Hz and 240 V/50 Hz, allowing for global use.

Key Benefits

- Power amplifier of a discrete design in an all-metal housing
- Two headphone outputs connected in parallel
- Volume control for both headphone outputs
- Looped-through input and output to connect between source and amplifier
- Internal wide-range switching power supply for worldwide use
- Supplied with two different power cables (1 x type E+F (CEE 7/7) and 1 x type B)
