Audio Pre-Amplifier
|
|
The B-Tech BT26 pre-amplifier is a small format
pre-amp ideal for use in confined areas where rack mount and desktop units
would be inconvenient. Inputs are provided for stereo & mono jacks, or
stereo left and right channel phono connectors. Outputs are right and left phono connectors on the
rear of the unit. The unit is ideal for connection of a microphone to
a PC, and can be used for most other line in and microphone combinations that
need to be pre-amplified. |
