If you have a receiver or integrated amplifier with a pre-out / main in loop, you can insert the
EQ901B as shown below.
The EQ901 PS does not have a power switch. We recommend that it be left powered on as
power consumption is very low. When you power the EQ901 PS off and on, ensure that you
turn the connected equipment off before disconnecting power from the EQ901 PS. Also,
connect power to the EQ901 PS before turning connected equipment on.
