14. MIC 1, MIC 2 and MIC 3 inputs
• (Mic 1: 5-pin DIN socket)
–60 dB*, 600 Ω, electronically balanced. Not
only a dynamic microphone but also phantom
powered microphone can connect with only this
MIC 1 input.
Use a 5-pin DIN plug connector when connecting
a phantom powered microphone to this input.
In this case please set phantom switch in ON.
When it connects Dynamic Microphone, please
set phantom switch in OFF by all means.
• (Mic2 & Mic 3 : Double pole phone jack)
–60 dB*, 600 Ω, electronically balanced.
Because microphone input is balanced type,
phone plug uses double pole type, but can use
even Single pole type.
(Refer to Input Connection in detail.)
15. AUX 1 and AUX 2 input terminals
–20 dB*, 10 kΩ, unbalanced. Monaural RCA pin
jacks. Accept external equipment output signal.
16. Recording output (REC OUT)
