Analog Line Input Connectors
The rear of the M-1620 Pro D features two 25-pin D-sub connectors labeled "LINE IN" with Tascam®-pinout.
These analog inputs are servo-balanced, allowing balanced and unbalanced signals to be connected without a difference in level.
When using unbalanced connections, be sure to connect pin 3 (negative/"cold") to pin 1 (ground), to avoid noise from the unconnected pin 3 input. |
