AUDIO CONNECTIONS

There are two ways to transmit audio signals to and from the UMC-1: Digital and Analog. The analog signal is an
electrical waveform representation of sound and it requires a cable for each channel. The digital signal uses a sequence
of numbers that represents the sound and requires only one cable for all channels.
You can connect your source components using an HDMI connector, RCA connector, OPTICAL connector and BALANCED
(subwoofer only).

CONNECTION TIPS FOR SUPERIOR SOUND

Before setting up your new system, please consider the following:
Whenever possible, route the power cord away from the signal cables or speaker wires to prevent any hum or
interference heard in the speakers.
Use high quality coaxial digital cables to connect the UMC-1 to any source equipment which has coaxial digital outputs.
Optical cables transmit only light pulses and are much more immune to noises but are sensitive to excessive tight
bends. Whichever you choose, follow the cable manufacturer's recommendations.
Many RCA type patch cords can be a very tight fit and there is usually a preferred method of getting them off. Some
have to be removed with a twisting action. Be gentle or you may damage the jacks of your UMC-1, or other
components.
Many audiophile signal cables are intended to be hooked up in one direction. If this is the case the cables will be
marked with arrows in the direction of the signal flow.
It is usual for the right channel RCA patch cords plugs to be red and the left channel connections to be white, grey or
black (depending on the cable brand). RCA connectors that are gold will be designated with a colored band to designate
the channel.
If the powered subwoofer to which you will connect the UMC-1 features a balanced XLR input, use the
UMC-1's XLR balanced SUB output instead of an RCA type patch cord if possible. Balanced signal
transmission between the UMC-1 and the subwoofer will provide superior rejection of hum and noise,
especially if long cable runs are required.
