NOTE:
1. Unless otherwise specified, the unit is shipped as AC coupled.
2. Specify AC power-line voltage at the time of ordering.
3. The amplifiers are adjusted as all outputs terminated by a 75ohm load. Unused output must be terminated by a 75ohm load
    to ensure stable operation and flat frequency response.
