Figure 1–7 AUX 2 - AES Input Termination
• AUX 1 & 2 Input 1 & 2 (on BNC): The four BNC connectors in the 
AUX 1 and AUX 2 input sections accept standard AES audio signals 
and are configured for unbalanced connections (75  impedance). 
See the Audio Source Select button and the Audio Analog/AES 
Select button for instructions for selecting these inputs for 
monitoring.
• External Speakers (Speaker Binding Posts, Left and Right): Connect 
external speakers to these binding post terminals. The left pair 
outputs the signals as selected for the left speaker and the right pair 
outputs the signals as selected for the right speaker. The binding 
post terminals in each output pair are color-coded for polarity; red 
is positive (left terminal) and black is negative (right terminal). An 
external amplifier is not needed to drive the external speakers. 
• VAMP2 Analog In & Metered Analog Out (DB-25-F): This 
connector accepts balanced, low impedance, line level analog 
signals. See Figure 1–8 below for pin-out information. This 
connector has the same pin-out as the Tascam analog DB-25.
