<Notes for cascading>
To cascade PH-100s, connect between the
[CASCADE OUT] jacks (L, R) of the first unit
and the unbalanced [INPUT (-10 dBV)] jacks
(L, R) of the second unit. In the same way,
connect between the second and third units.
By setting the [INPUT] control of the second
and third units to the "CAL" position, you
can control all headphone output levels
using the [INPUT] control of the first unit.
