Custom Made Cables (Non-Cello)
Three-conductor shield cables should be used to keep audio(+), audio(-), audio
ground and chassis earth separate. If single-ended adapters are made, pins one and
three should be jumped and used as ground and pin two should be used as the
audio(+).
Connecting audio ground and chassis ground may cause or solve grounding problems
depending on the system as a whole.
Electrical Connections
I)
Make sure the circuit breakers are "off'.
2)
Verify that AC mains voltages are set correctly.
3)
Connect the preamplifier or other driving equipment.
4)
Connect speaker output cables.
5)
Be sure that the electrical service in the building/house is up to the task. The
recommended ideal situation is a dedicated line to each set of amplifiers.
6)
Install AC cable into IEC mains connector on rear of each power amplifier.
7)
Connect AC cables to AC mains.
The Encore 150 Amplifier can be used as part of a complete Cello System, or in
conjunction with other speakers, electronics and cables.
Operation
The Encore 150 Amplifier is capable of producing extremely high voltage and
current levels. Be sure to observe standard precautions when operating. The
following steps are recommended.
1)
Be sure all electrical connections are correct. Triple check them.
2)
Do not run AC mains or audio cables under rugs or sharp objects.
3)
Turn peripheral source electronics on first. Avoid switching these on or off
while amplifiers are in use.
4)
Set volume controls on preamplifier to minimum.
5)
Turn amplifier switches on.
6)
Bring the volume control up slowly to the desired level. Use the amplifiers for
musical enjoyment. Do not overdrive to create distortion. The Encore 150
Amplifiers are capable of damaging loudspeakers if the volume is up too high.
