[Simultaneous Mic In and Line In Use]
・As an acoustic guitar preamp:
Mixes and outputs the signal picked up by the microphone and the signal from the pickup.
・As an instrument direct box or mic preamp.
Connect the instrument signal to the Line In and the mic signal to the Mic In.
[Insert]
Outputs the signal before passing through the high-pass filter and tube stage to an external processor for insertion.
[1-in, 3-out Preamp]
The signal input to the Hi-Z INPUT is output not only from the Main +4dB XLR and Main -10dB TRS phone jacks, but also from the Stack Out. (For example: XLR for recording equipment, TRS phone for a bass amp, and Stack Out for a headphone amp, etc.)

※About the 48V LED
Even when the power switch is set to the ""ON"" position, the 48V LED indicator may remain lit for a few minutes after powering on. This is a product specification. As long as the switch is set to the ""ON"" position, you can use microphones other than condenser microphones without any problems, even if the LED remains lit.
