5. Connecting the Cables

5.1. Power cables

AC power input is via a standard IEC socket. Operating voltage must only be

changed by an authorized service agent.

The quality of the power cable used will affect the sound quality.

5.2. Signal Cables

Single-ended version has only one RCA input connector. Balanced version has both

RCA and XLR input connectors. The RCA and XLR inputs are connected in parallel

inside the unit. Do not connect two source devices at the same time. A selector

switch (marked as SEL) allows you to bypass the input transformer. When the input

transformer is bypassed, the sound level will increase due to level differences of

balanced and unbalanced connection standards, but you lose true balanced input

features and the system may become more susceptible to noise.

5.3. Speaker Cables

Speaker binding posts can handle spade lugs, banana plugs or bare wire.

Polyethylene knobs are chosen instead of metal ones to reduce extra conductor

mass and eddy currents. Do not overtighten the binding posts. The higher friction of

polyethylene will secure the speaker cables.

There are two impedance options for speaker connection. You should use the

closest matching output with your speaker manufacturer's recommended value.

Since the output is transformer coupled, there is no output power difference when

using 4 or 8 ohm speakers.

Always use a combination of 0+4 ohm or 0+8 ohm terminals. Never combine 4 ohm

and 8 ohm terminals as a 4 ohm output.
