Can I connect an external HDD to ‘USB Audio In’ on the EDGE A?
No, there is no way to connect a USB drive or HDD directly to the EDGE A using its ‘USB Audio’ input. The ‘USB Audio’ input on the EDGE A will only support a direct connection with a PC or Mac. You will, however, be able to use one of our network players in combination with the EDGE A to do this.
Why does the EDGE A not have tone controls?
The decision not to include tone controls for the EDGE A was made in order to ensure it produces an unprocessed, accurate and natural sound that is as faithful to the original recording as possible.
Why does the volume knob move when the EDGE A powers on?
The first time the EDGE A is powered on after a factory reset it will perform a calibration process which takes approximately 30 seconds.
Please allow this process to complete before attempting to use the product.
Can I use a Turntable with my EDGE A?
You can connect a turntable to either of the EDGE A's RCA analogue inputs, however, as the amplifier does not have a built-in phono stage, you will require an external phono stage between the turntable and the EDGE A, or a turntable with its own integrated phono stage.
A phono stage boosts the low output from a turntable to 'line level' to allow connection to an amplifier as well as ensuring a minimal amount of noise and distortion within the signal.
As the amplifier has no phono stage built in, it is also not fitted with a Turntable Earth. Our phono stages have an earth for this reason.
If you are using another manufacturer's phono stage that is not fitted with an earthing connection, you will need to consult with the turntable manufacturer for earthing options.
What amplification class does the EDGE A use?
The EDGE A uses Class XA amplification. For Class XA, the crossover point is moved so that both sets of transistors are always on until the signal reaches a loud enough level.
This means that for low level signals, the amplifier is essentially operating as a Class A amplifier and it is only when the signal is sufficiently loud enough that the transistors switch over. Any crossover distortion is therefore masked within the signal.
