twice the level (x2). -6dB is half the level (50% lower).
As shown in the display screen, when the volume control is turned fully clockwise to the maximum output level, the pre-amplifier gain is 0dB (x1).
When the volume control is turned anti-clockwise until it reaches -80dB, that is the maximum attenuation or, minimum signal level. One more
click anti-clockwise will Mute the output.
Volume levels can be adjusted in 1 dB steps from 0dB down to -50dB.
From -50dB down to -80dB can be adjusted only in 3dB steps.
The power amplifier circuit has an overall gain of +33.4dB, or x47 amplification factor.
In other words, if a constant 100mV (0.1 Volt) sine-wave signal is input with the volume set for 0dB (maximum), the output voltage will be (0.1 x 47)
4.7V RMS.
To reach 120 Watts maximum undistorted output level into an 8 Ohm load, or 240 Watts into 4 Ohms, an input signal level of 659mV (0.659 Volts)
is required. The volume control can only attenuate the incoming signal and not amplify it. Therefore, having the volume control set to -6dB
reduces the input level by half, so the amplifier can only output 60W into 8 Ohms or 120W into 4 Ohms.
If your source produces a low signal level it will require less attenuation to make the amplifier sound loud enough. So, 0dB may not always be
enough for all circumstances. Therefore, the Voyage i20 has been designed with helpful pre-amp gain options.
If greater overall sensitivity is required, the pre-amplifier gain can be increased in four steps on any, or all, of its four analogue inputs.

USB from PC using Win10+
Plug a good quality printer cable, USB type A male to USB type B male, from a spare port on your PC, laptop, or network device to the USB port
on the rear of the amplifier. Avoid using cables longer than 5 metres as the i20 USB input may not work reliably.
When connecting initially, your computer will detect the Voyage USB Audio 2.0 device as an external sound card and flag that it is searching
for the driver, providing the computer is connected to the internet. Once the Voyage USB Audio 2.0 is discovered, it will automatically go to the
