With the introduction of the A1, beyerdynamic enters a new area of audio reproduction.
After intense fundamental research, beyerdynamic have succeeded in developing a brand new audiophile-quality headphone amplifier, providing precise audio performance even when used with our demanding 600 ohm premium line headphones.
With its unique intelligent-circuit concept, the A1 is capable of reproducing an amazingly wide frequency range which stretches way above human perception.
As an example, the entire circuit is capable of handling frequencies of up to 96 kHz, which enables the transfer of uncompressed audio from either SA-CD or DVD Audio.
A micro-processor-controlled relay allows noiseless switching between two different high quality audio signals and avoids unpleasant clicking when powering the A1 on or off.
Underneath the large front-panel-mounted aluminium volume control is a high grade ALPS-potentiometer for smooth volume adjustment.
This is just part of the attention to detail that ranges from the outer unit construction to its quality integral components - use of a generously-dimensioned toroidal core transformer, plus a combination of carefully selected components allows even the highest-impedance headphones to be driven flawlessly over the entire frequency range.
The provision of a high impedance headphone output ensures that the control range of the volume potentiometer is also ideal for headphones with lower impedance.
The first of the two provided line-ins is hardwired to the A1 line out. The result allows the incoming signal to be loopedthrough even with the A1 in standby mode.
So you only have to power up the A1 if you want to increase the enjoyment of your music using your headphones.
Two blue LEDs in the front panel monitor the active signal input, with a further multicolour LED giving information about the A1’s operating status.
The beyerdynamic A1 - The uncompromising “true companion” for your headphones and a pure masterpiece in audio achievement.
