Getting Started
1. Make all connections with the power off and the volume knob
turned all the way down until it clicks.
2. Connect the active speaker and passive speaker with the
included speaker cable (red cable to red wire clamp, and
black cable to the black wire clamp). The powered speaker is
designed to be placed on the left, and the passive speaker on
the right.
3. Connect your audio source using either the TRS or RCA
connectors using the appropriate cables (not included). A
mini-jack to RCA cable is provided to connect to a computer
or smart device’s headphone or line output. Refer to the
connection diagrams on the next page for details. Note that
the output of the speakers is the sum of all inputs. Unless you
specically want to listen to a mix of different sources, only
one audio input should be in active use at a time.
4. Connect the power cord to a power outlet and set the power
switch on the rear panel to On.
5. Press play on your audio source and slowly turn the volume
knob on the front panel up to the desired volume. The knob will
