Balanced headphone connections.
For best drive performance, it is recommended that the headphones be driven using a balanced pair
of wires (positive and negative phase) independent of each channel. When connecting balanced
headphones, you need to avoid midpoint or common ground connections.
The H26 headphone amplifier provides two different connectors for connecting balanced
headphones, with specific pin assignments as shown below:
1. 4-pin XLR connector (male).
Example: Neutrik NC4MC-B connector.
Signal connections are as follows:
Pin 1=Left+ Pin 3=Right+
Pin 2=Left- Pin 4=Right-
2. 4.4 jack
