Fostex Example -3 Cascading PH-100, External device, First unit, Second unit, Third unit

Model PH-100

<Example -3: Cascading PH-100>

The following figure shows the example of cascading three PH-100s, allowing 30 persons to monitor the same stereo source. You can cascade up to 10 PH-100s (allowing 100 persons to monitor).

Note that we do not guarantee the function when cascading more than ten PH-100s.

<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.
