These analog inputs are servo-balanced, allowing balanced and unbalanced signals to be connected
without a difference in level.
The last six input channels (Ch. 11 - 16) are additionally provided as balanced TRS input jacks (6.3 mm,
1/4"). They are internally connected to the corresponding D-Sub input channels and can therefore not be
used at the same time.
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.
3.10. Analog Line Output Connectors
The rear of the M-1610 Pro features a 25-pin D-sub connectors labeled "LINE OUT" with Tascam®-pinout.
The short circuit protected, low impedance balanced line outputs at the D-Sub connectors
do not operate servo balanced. When connecting unbalanced equipment, make sure pin 3
("cold") of the output is not connected. A connection to ground may cause a decreased
THD (higher distortion) and increased power consumption!
In addition, the first two analog output channels are available on separate TRS connectors. These
outputs have their own driver stage and can be used in combination with the corresponding D-Sub
channels. "Analog Out 1, 2" in the output routing controls both the two TRS output channels and the D-
Sub channels 1 and 2.
The TRS output stages have a servo balanced design. Therefore unbalanced TS plugs can be used
without a difference in output level. This is different from the Phones output in balanced mode, where TS
plugs should not be used.
The maximum output power at the TRS connectors is +19 dBu (balanced and unbalanced).
This reference level is also applied when switching output ch. 1, 2 to +24 dBu. The higher
reference level is only available at the D-Sub connectors.
