How do I select the Balanced or Unbalanced inputs on the EXA?
On the EXA, pressing the A1 input selection button will toggle between the balanced and unbalanced inputs. The balanced input is shown by A1 being lit orange, while the unbalanced input is shown by A1 being lit blue.
Please ensure that the correct input is selected on the EXA, depending on how your EXA is connected. If the wrong input is selected, then there will be no sound from the amplifier.
Can I connect an external HDD to ‘USB Audio In’ on the EXA100?
No, there is no way to connect a USB drive or HDD directly to the EXA100 using its ‘USB Audio’ input. The ‘USB Audio’ input on the EXA100 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 EXA100 to do this.
Why can’t I adjust the volume of the EXA100 with my mobile device when connected via Bluetooth?
When using Bluetooth with the EXA100, the amplifier’s volume control takes over from the mobile devices’ volume. The mobile device then produces a Bluetooth stream of fixed level volume, which is then adjusted at the amplifier’s end.
It is normal behavior for some mobile device nots to be able to control the volume of the EXA100 when connected via Bluetooth. Volume adjustments can be made on the amplifier itself, using either the remote control or the front panel volume knob.
What is the crossover frequency on the EXA100?
The EXA100 has a low pass filter of 2.3 kHz applied at the Sub Out output. This is so that there is minimal phase added by the EXA at the Sub Out frequencies. This allows you to set your own crossover frequency on the Subwoofer itself.
What would the power output of the EXA be if I connect two pairs of speakers?
When you connect two pairs of speakers to an amplifier, the combined impedance is halved. So, when two pairs of 8Ω (Ohm) speakers are connected, the overall impedance becomes 4Ω, even though the individual impedance for each speaker remains unchanged at 8Ω. The EXA100 outputs are rated at 100 RMS at 8Ω which is increased to 155W at 4Ω.
It is not recommended to connect 2 pairs of 4 Ohm or 6 Ohm speakers to the EXA100, as the impedance is halved meaning the impedance will be 2 Ohms or 3 Ohms respectively. This could result in the amplifier being driven too hard and CAP4 protection being activated, or damage being done to the amplifier and/or speakers.
Will the EXA100 playback 32-bit files via the USB Audio input?
Whilst the EXA's hardware is capable of handling 32-bit audio via the USB Audio input, the USB interface is reporting the host to be only 24- bit capable.
If you attempt to play 32-bit files, the USB driver will convert them to 24-bit by removing the least significant information.
