HB7 Headphone Buffer
HB7HeadphoneBuffer
Overview
The HB7 headphone buffer is used to amplify signals for headphones. The HB7 is
a two channel device. The outputs include both a stereo headphone jack and Left
and Right BNC connectors. The output level can be controlled with a Gain knob,
and there is a Differential switch that allows the LEFT input to be output to the Left
and Right outputs resulting in an additional 6 dB of gain.
Power
The HB7 Headphone Buffer is powered via the System 3 zBus (ZB1PS). No PC
interface is required.
Features
Inputs
The HB7 has two inputs for signals up to ±10 V, accessed through front panel BNC
connectors labeled LEFT and RIGHT.
Outputs
The outputs include both a stereo headphone jack labeled PHONO and Left and
Right BNC connectors.
Note: When monitoring both output channels with only one input connected, users should
short the unused input channel to ensure maximum channel separation.
Gain
A single GAIN knob provides control over the signal output level in 3 dB steps from
0 to -27 dB.
