Connecting the SAM-A1 to your other audio equipment:
Note the audio source connected to the inputs must be a big enough amplitude/voltage to drive
the amplifier, i.e. a turntable/record player with an output of only a few tens of millivolts will
require a preamplifier to get the signal up to the 250 – 500mV input required by the SAM-A1
amplifier.
If your audio source already has a compatible signal it may be connected directly to the SAM-A1
inputs as shown with the dotted lines.
Bluetooth connectivity to your existing devices (e.g. phones, tablets) can be achieved by using an
external Bluetooth Audio receiver. We have only tried one – an MPOW BH070. This device worked
as advertised and did not add any significant hum or hiss even when plugged in to a USB plugtop
charger.
