MONO CLASS D AMPLIFIERS
INTRODUCTION Thank you for purchasing a Cadence Type RS amplifier. Over the past years, the technology used to create audio amplifiers has grown by leaps and bounds. We have thousands of satisfied customers still using our first generation Ultra Drive amplifiers which are almost 10 years old. Our competition is satisfied with just continuing to build the same units year after year without thought for improvement, but not us.
FEATURES GOLD PLATED TERMINALS: All the terminals on the amplifier are solid brass and satin nickel plated for high conductivity and minimum impedance loss. The power and ground terminals are extra large and capable of accepting 2 gauge wire. The speaker terminals can accept 8 gauge wire. When wiring the amplifier, be sure to strip just enough wire that fits into the terminal so that bare wires do not touch each other, or the amplifier chassis and cause a short circuit.
FEATURES AMPLIFIER MODE SWITCH This switch enables you to slave multiple RS amplifiers off one master. Input signal will be connected to the master in a system, and then a PM2 bridging cable can be used to connect the master out to the slave in of a second amplifier, and in multiple amplifier systems, this amplifier’s master output can be connected to a third amplifier’s slave input, thus allowing the daisy chaining of an almost unlimited number of amplifiers from one signal source.
INSTALLATION BASICS INSTALLATION BASICS: Before you begin with your installation disconnect the NEGATIVE (-) terminal from your car's battery. This safety precaution will avoid possible short circuits while wiring your amplifier. Cadence amplifiers operate on 12-volt negative ground systems only. It is recommend that you layout your sound system design on paper first. This will help you during the installation so that you will have a wiring flow chart and not miss-wire any of your components.
MOUNTING MOUNTING THE RS AMPLIFIERS: Choose a convenient mounting location with unobstructed airflow. 1 - Mount and fasten amplifier bracket A onto the mounting surface, with two screws as shown. 2 - Slide the amplifier so that hook B engages with bracket A. 3 - Fasten the front of the amplifier to the mounting surface with screws as shown.

USING THE CPR REMOTE CONTROL WITH THE RS AMPLIFIERS CPR (COMPETITION PODIUM REMOTE) BASICS The optional CPR remote control can be used for street or SPL competitions alike. The CPR is an optional unit and not included with the ZRS amplifiers. Please see your dealer for pricing and availability of the CPR. Apart from the usual level control, it also sports a few extra features that SPL competitors especially will find handy.
ADJUSTING THE SYSTEM 9 SETTING THE TOP PANEL CONTROLS ADJUSTING THE SYSTEM AUDIO PREAMP INPUT The RS 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.

BASIC SPEAKER WIRING DIAGRAMS FOR VARIOUS LOADS SERIES: SINGLE VOICE COIL SPEAKERS NOTES ABOUT USING MUTLTIPLE SPEAKERS: Please note that the minimum impedance load for single Cadence Type RS amplifiers is 1 ohm. If you choose to mono bridge two RS amplifiers into on load, the impedance should not be lower than 2 ohm. Lower impedance loads will cause overheating and may damage the amplifiers.

TROUBLESHOOTING HOW TO TROUBLE SHOOT A SYSTEM GENERAL A car stereo system consists of many different pieces of equipment connected together, and a logical process of elimination will find the problem area, by isolating sections, and checking them one at a time. Before following the instructions below, check and double check all wiring and connections.
