Installation – getting connected

Caution: All connections and switching must be done with the amplifier powered

off. Do not connect the power cord to the amplifier until your connections and set

up is complete.

Inputs

For line level connections, use high-quality RCA cables that feature low

impedance, shielding and high-quality connectors.

Speaker outputs

Use 14-18 gauge stranded two-conductor loudspeaker wire for all high level

connections. At each loudspeaker-level connection, ensure that at least 2 inches

of each conductor are separated. Strip away 1/4 inch of insulation from each

conductor. Connect the appropriate conductor to the speaker connection using

the Phoenix-style connectors, observing correct polarity.

Verifying phase

If during or after calibrating your receiver you suspect the sound is not right and

you cannot see any markings on the wire to verify that polarity is correct, try this

simple test:

1. Sit in the normal listening position for the system.

2. Play some music with your receiver set to Mono. Listen to the music and

observe the audio.

Does the bass sound full and even with the other audio?

Do the vocals sound centered and even in volume? If any of the answers are

YES, follow steps 3 and 4.

3. Turn off your receiver and reverse the connections for one of the speakers.

4. Repeat your test at the same volume level while reversing connections for

each speaker, one by one. When the sound has the loudest and best

sounding bass, and vocals are centered and clear, your connections are

correct and in-phase.

Loop outputs

Any source connected to the Global Line In Input can be sent to other

components or amplifiers by connecting them to the Global Loop output

connectors.
