VERIFYING PHASE
When proper polarity is not maintained, the speakers play at the opposite ‘time’ from each other, or out of phase. The result is
audio with lack of bass and vocals that sound thin or distant.
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 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. 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 Line In Input can be sent to other components or amplifiers by connecting them to the Global Loop
