via a high speed, high temperature capacitance bank and 100% pure copper rails on the PCB
enabling fast transient response to musical demands. The audio output section of the RS amplifiers
feature high speed high voltage, low Rdson MosFET transistors. This design contributes to ultra low
distortion and extreme high power
capabilities.

Our proprietary Class D modulation scheme, in conjunction with a very carefully designed output
filter, ensure clean, accurate sound reproduction with authority for deep slamming true bass.This
sophisticated circuit constantly monitors the heatsink internal temperature and various volt ages,
adjusting the amp automatically and protecting it from dangerous conditions. The 2 LEDs located on
the input side of the amplifier provide indication of the amplifier status, and the Power LED will light
Green when the amplifier is receiving proper power, ground and remote voltages and the IC
monitoring sequence indicates the amp is functional. In case the amplifier encounters a diagnostic
condition as listed below, the second LED will turn RED indicating a Diagnostic condition. When a
diagnostic condition is sensed the amplifier will then turn into a self preservation mode and if the
cause of the diagnostic condition is not corrected will eventually shut off. There are certain critical
diagnostic conditions which will turn the amplifier off immediately. 1. Speaker short circuit. 2. Input
Overload. 3. Thermal overload. 4. Reverse Polarity. T o reset the amplifier, you must first diagnose
what caused the problem, correct the fault and restart the system. See the T rouble Shooting page
for further details. A unique feature of the Cadence T ype RS amplifiers, is their direct capacitor
connection to the amplifiers internal power supply. As you know, the speed in which the reserve
capacity of any stiffening capacitors reaching the amplifiers power supply is critical. Y ou want this
reserve voltage to be immediately available upon your amps hitting a bass note. Our terminal
connection puts the negative of the capacitor in direct line with the negative terminals of the power
supply MosFETs and the positive of the capacitor with the center tap of the power supply
transformer coil. In essence, its like your amplifier having its own personal battery.
The RS amplifiers feature an antithump, mute and delay circuit. This eliminates irritating and
speaker damaging turnon and turnoff transients normally experienced with less expensive
amplifiers. Boom ! Harder Cadence T ype RS amplifiers have tighter sounding bass reproduction
thanks to this unique circuitry. Cadence RS amplifiers are rated and regulated to 13.8 volts and
below. Increasing voltage to 14.4 volts will increase the power output of the amplifier in the same
proportion. Maximum input voltage is 16 volts while the minimum voltage is 12 volt s. Due to the
extreme high power capabilities of these amplifiers, they feature a builtin induction fan cooling
system. The amplifiers draw in cool air through the nosepiece side vents, for circulation across the
circuitry. The main heatsink for the amplifier and power supply sections is a CAD designed forced
cooled tunnel that runs the length of the amplifiers. A fan at each end, one pulling air in, and the
other forcing air out, ensure that the power electronics stay cool for continued, clean operation. It is
important not to block either the input or exhaust ports. Some of our competitors are more
interested in making a quick buck and will purposely leave the fan out of their amps and then charge
you a hefty sum to buy and add the fan on later. At Cadence, if we feel that our amplifiers will work
better with a fan then we install it at the factory and dont make it an expensive add on option.
Cadence amplifiers incorporate many outstanding protection circuit s to help protect the amplifier
from being damaged during operating conditions. If you live in a hot climate we suggest installing
additional cooling fans in your trunk to exhaust the hot air which can build up in the trunk this will
help keep the ambient temperature in the trunk as low as possible so that your amps work flawlessly
and without any musical interruption. Clipping or total shutdown may also be a result of a bad
ground connection or loose ground.
If you find that your speakers and speaker wires are not shorted, please check your ground
connection. Thermal Protection When the amplifier reaches an unsafe operating temperature of 80
