4. Connect Signal Cables
Connect the input source to the amplifier’s right and left channel RCA jacks. Refer to rear
chassis drawing for connection location. These jacks are labeled with colored washers: red
for right and black for left.
5. Connect Speaker Cables
Connect the speaker cables. Refer to rear chassis drawing for speaker connector location.
Be sure the positive speaker lead is connected to the plus symbol on the speaker connector
(In this case, red to red, black to black) Note: NEVER switch on the amplifier unless a
speaker is connected to both output terminals. Operation of the amplifier without a load may
damage the output transformers.
Operating Tips
A. Power cord, plugs and sockets
The power cord should be routed so that it is not likely to be stepped on or pinched by items
placed upon or against it. All the plugs and sockets supplied with your Consonance
equipment have been chosen because they mark the best possible connection for their
purpose. A poor contact will degrade the signal substantially, plugs and sockets should look
clean and free from corrosion. The easiest way to clean them is to switch off the equipment,
pull the plugs out of their sockets, and push them back in again. Special contact cleaners
and contact enhancers should not be used as they tend to deposit a film, which is very
difficult to remove and may degrade the sound.
B. Switching on and off
Source components and power supplies for CD players, tuners, preamplifiers and crossovers
should be switched on before switching on the amplifier(s). Always switch the amplifier(s) off
and wait about 5 minute for its power supply capacitors to discharge before connecting or
disconnecting any leads. Always use the power switch on the equipment instead of the
mains outlet switch.
C. Running in
Your Consonance equipment will take a considerable time to run-in before it performs at its
best. The duration varies, but under some conditions you will find that the sound continues to
improve for as much as five weeks. Better and more consistent performance will be achieved
if the system is left switched on for long periods. However, please take note that all electronic
equipment can be damaged by lightning and should not be left on for long periods
unattended.
D. Power supply
Where fused plugs are used various amp fuses should be fitted. Fuses of a lower rating will
fail after a period of use. A hi-fi system usually shares a main circuit with other household
equipment some of which can cause distortion of the mains waveform. In some Consonance
equipments such distortion can lead to a mechanical hum from the transformers. The hum is
not transmitted through the speakers and has no effect on the performance of the system but
is purely local to the transformer. A separate fused mains circuit (like that reserved for
electric cookers) will have lower impedance, supply cleaner power, and consequently
improve system performance. Do not wire voltage dependent resistors or noise suppressors
into mains plugs. They degrade the mains supply and the sound.
