Power Amplifiers - YORKVILLE M608 Manuel De L'utilisateur

ii. To adjust for deficiencies in the speaker system's high frequency and bass response,
the M608 also has a 2-band rotary shelving equalizer. These work in conjunction with
the 9-band graphic. Yorkville engineers have developed this technique to provide
you with greater tone shaping capability. This allows the graphic equalizer bands fre-
quencies to be spaced at closer intervals, which mean better selectivity for feedback
reduction and sound shaping. You may want to turn up the Lo and Hi controls to
give the system a more HiFi sound when you're playing at lower volumes. At higher
volume levels, you may need to turn these controls down, this will help maximize
the volume and tighten up the sound.
iii. The third use of the graphic equalizer is to adjust the sound character for artistic
reasons. The frequencies are adjusted until the sound feels best to the musicians.

1. Power Amplifiers

Each of the M608 dual power amplifiers has two ¼-inch jacks and 1 Speakon jack for
speaker connections. The power amplifiers are designed to provide full power into a 4 to
8-ohm load. Connecting two 4-ohm speakers (2-ohm load) to either AMP A or AMP B will
not harm the M608 but the maximum power output may be slightly reduced.
WARNING: Do not obstruct the flow of air around the vents on the rear of the M608,
this may cause the power amplifier to overheat. The amplifier will start to reduce its
power output in order to keep running. In extreme cases it may be forced to shut
down. After the M608 cools down, operation will be restored automatically This con-
dition should not occur if adequate ventilation is provided at the back of the unit.
2. Power Switch and Breaker
The Power switch and circuit breaker are located on the rear panel. If the circuit breaker
trips during use, wait a few minutes (to cool), then push in to reset. The circuit breaker
can trip if the amplifier is too heavily loaded with long periods of continuous tones (such
as feedback). If the circuit breaker trips immediately after being reset, take the unit to
your Yorkville dealer for service.
