Cadence M7000 Car Amplifier User Manual


 
Over the years we have received many an amp back to our service department
with melted power/ground terminals. The cause of this is a bad ground
connection. When there is a lack of good ground heat builds up at the weakest
point which is the contact screw of the terminal.
Over time the heat generated will begin to melt the terminal. It is a good
practice to feel the power and ground wires with your hands, near their
amplifier connection after having played the amp for a while. If the wires feel
hot to the touch you probably have a bad or loose connection. If you are sure
of your connections and the wires still feel hot to the touch, you should
upgrade the gauge of the wire to next heaviest gauge.
REMOTE TURN ON CONNECTION
The remote turn on connection is located on the barrier strip next to the
power and ground connections. This connection is responsible for turning the
amplifier on and off with the rest of the system. A smaller gauge wire can be
used to make this connection to your radio's power antenna lead. Should your
system not have any turn on leads, you can wire the remote terminal to an
accessory lead, which turns on, with your ignition.
SETTING THE CONTROLS
AUDIO PREAMP INPUT
The Amadeus Series amplifiers feature RCA preamp inputs. Run RCA cables
from your sound source to the inputs of the amplifier. We suggest the use of
high quality shielded RCA patch cords to help reduce and eliminate
unwanted electrical noise from your system.
Be sure to run the RCA cables on the opposite side of the vehicle that you used
to carry the power and ground leads of the amplifier.
USING THE M7000 AMPLIFIER IN CONJUNCTION WITH
A MULTI-CHANNEL AMPLIFIER
The Amadeus M7000 amplifier is of course meant for sub bass applications
and as such needs to be used in conjunction with a second amplifier for a
complete system.
Connect the Line Out of the M7000 amplifier to the Line Input of a multi-
channel amplifier. Set the multi-channel amplifier's internal crossover to High
Pass, as it will drive the high frequency speakers, such as separates, coaxials, or
plate type speakers, typically mounted in the doors or kick panels.
USING THE BUILT-IN LOW PASS ELECTRONIC CROSSOVER
All the Amadeus Series amplifiers feature 24dB per octave fully adjustable
low-pass and high pass electronic crossovers.
For Low Pass systems, set the crossover mode switch to LOW PASS. Now the
