1. Place the input selector switch to Phono CD/DVD (up position).
2. Connect the your source device to the corresponding RCA inputs at the rear of the unit.

Optical/Coaxial
Many TVs, Digital set-top boxes, game consoles, and DVD players have optical (fiber optic) or coaxial outputs. To connect via optical or coaxial input, follow the steps listed below.

1. Place the input selector switch to Optical/Coaxial (down position).
2. Set the Optical/Coaxial selector switch on the back of the unit to the desired input mode.
3. Use a digital optical audio cable or coaxial cable to connect the source to the desired input port on the amplifier.

Outputs
Speaker Output
The amplifier features left and right banana plug/binding post terminals to connect two speakers.  When connecting your speakers, be sure to observe correct polarity. The total impedance of your speakers must not be less that 4 ohms.

Subwoofer Output

There are two RCA subwoofer outputs that are internally wired in parallel. You can use either one to feed the signal to a powered subwoofer. Here are various configurations you can use.

1. Use standard UR RCA jacks to feed the signal from both outputs to any powered sub with UR RCA inputs. Please note: since both outputs are putting out an identical mono signal, it doesn’t matter which one you hook the left and right RCA jacks to.
2. Use a monoaural RCA cable to feed the signal from either jack to any powered subwoofer with an LFE (Low Frequency Effect) RCA input or a single RCA sub input.

3.5mm Headphone Output
The 3.5mm headphone output is a direct plug and play connection. Simply connect your headphones and you are ready to listen. Please note, when the 3.5mm jack is in use, speaker output will be cut off.
