Digital input connector (optical)
Use this when you want to input a digital audio signal from a CD/MD/DAT or
similar device.
The signal input to the digital input connector is input as INPUT 5 and 6 (in
the case of WDM, EDIROL FA-66 In 3 ➔ see p. 31).
If you want to record this digital input signal, turn on the digital input switch
(7).
You must input a signal of the same sampling frequency as that selected by the
sample rate select switch (18).

Input jacks 3-4
Input jacks 3 and 4 are designed with a higher gain so that you can connect them
to audio devices that have a lower output level, such as CD players or MIDI sound
modules. If you connect these inputs to a device that has a higher output level, such
as a mixer, use this input level adjustment knob (27) to adjust the level.
If no device is connected to the Input jacks 3 and 4, turn the
input level adjustment knob (27) all the way toward the
left.
