Introduction 2 features 33 2 thank you for purchasing this cadence united series amplifier. Over the years, the technology used to create audio amplifiers has grown by leaps and bounds. We have tens of thousands of satisfied customers still using our first generation ultra drive amplifiers which are...

5 “arva” - automatic rail voltage adjustment circuitry: cadence united series amplifiers feature “arva” circuitry in their power supply. This circuit constantly monitors the output stage and under high current demands will adjust the power supply rail voltages so that enough power is available for p...

6 7 adjusting the system once the system is operational, the first thing to do, is set all crossover points to approximate settings. In the case of the basic sub woofer system low pass filter crossover at 100 hz or so. Set the bass boost equalizer controls to 0 db ( flat switch position.) now you sh...

4 channel amp with 2 channel input 8 9 if your head unit has only one pair of left and right rca out put jacks, plug them in to rca input jacks 1 and 2 of the amplifier and set the input model switch to the 2ch position. The amplifier preamp circuit will automatically mix the signals to channels 3 a...

10 11 install any combination of speakers independently on all 4 channels being careful not to load any single channel below 2 ohm stereo. For typical 6” x 9” or 6.5” or component speaker installs, set the crossover mode switch to full range. When bridging the four channel amplifier, make sure that ...

12 13 channels 1 and 2 should be wired to speakers no lower than 2 ohm loads per channel in stereo. Channel 3 and 4 should be bridged as per the diagram wiring the woofer to channel 3 positive side (+) and channel 4 negative side ( – ) terminals. Set the crossover mode switch of channels 1 and 2 to ...

14 15 if your head unit has one single pair of rca outputs, input them in to the amplifiers channel 1 and 2 input jacks and set the input mode switch to 2ch. The amplifiers preamp circuitry will automatically mix all the channels and output will occur on all 5 channels. There will be left and right ...

16 17 minimum impedance for channels 1 through 4 is 2 ohm stereo. Channel five minimum impedance is 2 ohm mono capable. Phoenix is a 2 ohm mono block amplifier. No matter how many woofers you choose to wire up to this model, the final impedance should not fall below 2 ohms. Please see page 26 and 27...

18 19 the dakota and olympia are 1 ohm stable mono block amplifiers. They feature rca pre amp line outputs for feeding of a full range signal to a secondary full range amplifier in a multi-amp system. The dakota and olympia are 1 ohm mono block class d amplifiers. No matter how many woofers you choo...

20 21 the dakota or olympia can be bridged together for double the power output into a 2-ohm load. Though each amp is 1 ohm stable, when bridging amplifiers, you must bridge them to a 2 ohm load. Input the head unit signal into the master amplifier and set the bridged mode switch to master. Use the ...

22 23 once again, when bridging two amplifiers together, the final impedance load of the bridged amplifiers should be no lower than 2-ohms. Double power will occur at 2-ohms. Master amplifiers positive (+) speaker terminal should be wired to the positive terminal of the subwoofer. Slave amplifiers p...
