Headphone Outputs
These channels can also be monitored with the on-board headphone amplifier. The channel listened to is selected via switches SW2 and SW3.
Moving the switch to the right will enable the corresponding channel. There are right and left volume sliders (RV3 and RV4) to allow
variations in volume level and balance control. Headphones should be plugged in to the J13 1/8-inch headphone connector.
2.5.3.1
SW2 / SW3 — Channel Select
These switches control what is routed to the on-board headphone amplifier. Moving the switch to the right will enable the corresponding
channel. Multiple switches/channels can be enabled at one time, and the signals will be summed into the corresponding headphone channel.
2.5.3.2
RV3 / RV4 — Headphone Volume Select
These sliders allow for volume and balance adjustment for the headphone amplifier. To help prevent damage to headphones or hearing, always
start with the sliders in a low-volume position.

Mode Selection
Various boot-up modes can be selected via the MODE pins and pins PB13 and PB14 settings can be determined using switch bank SW1.
Switch position “ON”= signal high.
Table 3-1
shows the modes available for the 56362/366/367.
Table 3-2
shows the modes available for the
56364. See device-specific user manual for full details of each boot mode.
NOTE
All other modes are reserved and should not be used.
