- Page 2 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.
- Page 3 See the Trouble Shooting page for further details. STIFFENING CAPACITOR DIRECT CONECTION: A unique feature of the Cadence Type RS amplifiers, is their direct capacitor connection to the amplifier's internal power supply. As you know, the speed in which the reserve capacity of any stiffening capacitors reaching the amplifier's power supply is critical.
- Page 4 At Cadence, if we feel that our amplifiers will work better with a fan then we install it at the factory and don't make it an expensive add on option.

Mount a master fuse right at the battery + terminal as shown. Add up the current draw for all amplifiers in the system to determine the rating for this fuse. Use a power distribution block, such as the Cadence FH-1, FH-2 or FH-3 at the amplifier location to supply +12 volt to each amplifier. - Page 6 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.

SETTING THE TOP PANEL CONTROLS 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. - Page 10 Mount a master fuse right at the battery + terminal as shown. Add up the current draw for all amplifiers in the system to determine the rating for this fuse. Use a power distribution block, such as the Cadence FH-1, FH-2 or FH-3 at the amplifier location to supply +12 volt to each amplifier.
- Page 11 NOTES ON MULTIPLE AMPLIFIERS AND SPEAKER PHASE MONOBRIDGING MULTIPLE PAIRS OF AMPLIFIERS The phase of each monobridged speaker per amplifier pair is the same. See the diagram on the right. 2 OR MORE AMPLIFIERS WITH SEPARATE SPEAKERS ON EACH Please note that for this type of setup, the speaker phase on every alternate amplfier MUST be reversed in order to keep the acoustical phase of all speakers in the system in phase with each other.
- Page 12 BASIC SPEAKER WIRING DIAGRAMS FOR VARIOUS LOADS 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.
