Deep Sleep & Waking Up
If the unit is in Auto Sleep mode, it's possible to make it wake up automatically simply by sending audio above 0 dBu. Alternatively,
simply press the MODE switch.
The Auto wake up function requires part of the audio circuitry to be still powered. After 1 hour of inactivity while in Auto Sleep, the
unit enters "deep sleep" (which is the same as putting the unit into Sleep mode manually) to save the most power (less than 1 watt
power consumption).
In Deep Sleep, the only available mean of restoring operation is by manually pressing the MODE switch.
In Auto Sleep a brief light animation on the operating mode LEDs occurs every few seconds helping you to identify you are in Auto
Sleep and not Deep Sleep.
Input Stage - Low Pass Filter
Some DACs or Audio Interfaces, depending on the implementation, can exhibit excessive out-of-band noise. Whilst you won't
directly hear it, it may cause unwanted triggering of Bus Compressor and D-EQ side-chains. When that happens, you'll notice the
gain reduction meter being displaced (or the D-EQ indicators lit) with no audio being played. It may also cause increased noise-
floor at high 4K MODE distortion settings.
To combat this, The Bus+ allows you to engage a 18 dB/oct (3rd order) Low Pass Filter at 26 kHz. If you have The Bus+ connected
to an audio interface that exhibits this issue, you may need to engage this. The filter is applied on every input stage, including
External Input(s).
You toggle the LPF by pressing the right-hand D-EQ LF control. The activity LED indicates if the LPF is in or out.
If the LF control LED is RED, then the LPF is disabled (default).
If the LF control LED is GREEN, then the LPF is enabled.
LPF disabled (default) LPF enabled
