RUBITM(_Rapid-Be @ranched _knpulse) This new proprietary power sup-ply topology eliminates “power sags” during low frequency reproductionby rapidly increasing the duty cycle, stabilizing the power supply andallowing it to deliver the power required when reproducing low frequen-cies. Also, greater reserve gate power is stored for low voltage condi-tions that occur during extreme conditions.

STACTTM (STabilized Apex Qurent _Topology) Reduces power supplystress by 50%. Typical designs degrade the stereo image due to phasereversal of even-order harmonic distortion that occurs between the in-verted channels. In the STACT design, inversion is done at the poweramplifier drive stage. Since the fully symmetrical power amplifier pro-duces no even-harmonic distortion itself and all preamplifier circuitry isrun completely in-phase, no even harmonic distortion phase reversaloccurs.

TridentTM Protection Topology provides three types of protection:I. Output protection against short circuits or improper loads.2. Ground fault detection: Shuts down the amplifier when a significantvoltage (> 5Volts) fluctuation occurs between electrical (turn-on lead)and battery ground.3. Thermal Protection: Puts the amplifier into thermal rollback or shutsthe amplifier down in extreme thermal conditions.

Hawkins Bass Control provides a focused subwoofer boost (O-9dB at45Hz) and routes otherwise wasted amplifier power back to the audiblebandwidth.

Harmonic Bass AlignmentTM The 2nd and 3rd order harmonic peaksare critically aligned to fundamental peaks at low frequencies. Thisproduces tighter, more accurate bass reproduction.

Drive Delay IITM Amplifier section powers up 2 to 3 seconds after thepower supply eliminating turn-on pops. Turn off process is reversed:amplifier section turns off first, followed by the power supply.

Dynamically Optimized Power Grid TM . Power grid is evenly distrib-uted between primary and secondary power supplies, providing greaterdynamics and improved RF filtering.

ChassisinkTM All transistors are ideally located and sandwiched be-tween the circuit board and the heatsin k to provide cool efficient ampli-fier operation.

Differentially Balance RCA Input eliminates ground loop related noisein the audio.

Hawkins Bass Control - Theory and Use

The RUBICON204,404 and 604 amplifiers incorporates an on-board stag-gered electronic crossover, with full range RCA outputs to drive an externalamplifier. No external electronic crossover is necessary. The high and lowpass portions of the crossover can be set independently of one another.

In many car audio installations, there is a tendency for a “midbass boom.”Because of their interior dimensions, most cars will resonate or ring at thesemidbass frequencies. If we design the system so there is reduced ouput inthis region, the final response is very smooth and natural sounding. Thehigh pass crossover is independently variable from 65 to 220 Hz at 12 dB/Octave, and low pass crossover is independently variable from 30 to 120 Hzat 24 dB/Octave. (12 dB/Octave lowpass on RUBICON204)

For initial crossover setup, try setting the low pass filter to approximately60 Hz, and the high pass filter to approximately 100 Hz. Change the cross-over points to accommodate a good mixture of frequency response, powerhandling, and personal preference.

12 dB/Octave High Pass

Hawkins Bass Control (variable) is a unique subwoofer controlcircuit included with the Soundstream RUBICON and 604 am-plifier. It is capable of removing subsonic energy in program ma-terial below 45 Hz at 12 dB/Octave, while boosting subwooferfrequencies. The circuit consists of two controls. One engages asub sonic High Pass filter at 45 Hz, and the other adjusts theamount of boost (0 to +9 dB). The Hawkins Bass Control func-tions on either pair of channels (l&2 or 38~4) if their low pass filteris engaged.

The Boost control adjusts the amount of level applied at the set

tional bandwidth. This bandwidth is determined by many factors, including driverdesign, and enclosure type. It is possible to overdrive any subwoofer driver bysending powerful signals outside of its operational bandwidth. These potentiallydamaging signals can be removed by adding a subsonic filter. Figure 3 showsthe effectiveness of the Hawkins Bass Control on woofer excursion in a ventedenclosure. The woofer travels 7.5 mm at 10 Hz. With Hawkins Bass Controlproperly adjusted, this excursion can be reduced to less than 1 mm. This is ofgreat benefit to lowering woofer distortion and increasing output.

SELECTING THE SPEAKER OUTPUT MODE

Channels 1 through 4 of the RUBICON204, 404 and 604 amplifiers have theability to operate in any one of the following modes:

Stereo @TACT); Use this mode for stereo operation (left and right channels).

Bridged Mono; Use this mode to get a bridged mono output while using only theright channel input and gain control per pair of channels (for use with a singularmono input.)

[ INSTALLATION STEP 2

BALANCED / UNBALANCED INPUTThe RUBICON amplifier has the ability to accept either a standard Unbal-anced RCA signal input, or a Balanced “Pro Audio” style input signals with the useof the Soundstream BLT Balanced Line Transmitter or some other balanced lineaudio source. Before installing your system, you should decide upon whichsignal type you wish to run. There are advantages to both:

ADVANTAGESUnbalanced RCA outputs 2. Excellent noise cancellation(Industry Standard). characteristics.2. No Interface module is 3. Immune to noise radiated innecessary. the car audio environment.

The RUBICON amplifiers’ signal inputs accept a wide range of input level: from300 mVrms to 5.0 Vrms for both Balanced and Unbalanced inputs. For the bestS/N Ratio, we recommend that the input level controls be set as far down aspossible (rotated counter-clockwise), while maintaining an acceptable level ofoutput.

Using the “Unbalanced” RCA InputWhen using the Unbalanced RCA input, the RlGHT channel input signal switchMUST be in the “UNBAL” position. Also, when first installing the amplifier usingthis input configuration, we suggest that the left channel input signal switch be inthe “UNBAL” position as well. If you experience alternator wine or other instal-lation noise with both switches in the “UNBAL” Dosition, trv movinq the LEFTchannel inout sicanal switch to the “BAL” position. This should remove anysystem noise due to the installation.

Using the “Balanced” RCA InputWhen using the Balanced 6-pin DIN audio input, both switches MUST be in the“BAL” position. Also, we recommend that when using this input configuration, theinput level controls be set to the “minimum” position (rotated counter-clockwise).The system gain should then be adjusted on the BLT Balanced Line Transmitter,other other balanced line audio source.

( INSTALLATION STEP 3 )WIRING

POWER AND GROUNDTo ensure maximum output from your RUBICON amplifier, use high quality, low-loss power and ground cables and connections (4 gauge for 604). The RUBICONamplifiers will accept up to 8 gauge power and ground cables. Determine fromthe chart below the minimum gauge power and ground wire for your application.

CIRCUIT BREAKERS AND FUSESEXTERNALLike all audio components, the RUBICON amplifiers must be fused near thebattery. A fuse or circuit breaker must be located within 18” of the batterv. This willprevent a fire in the event of a shorted cable. See the chart below to determine thecorrect fuse value.

INTERNALThe RUBICON amplifiers are fused with automotive-type fuses. In the event ofblown power supply fuses, replace with the correct value fuse found in the chartbelow. Never replace the fuse with a higher value than what is supplied. Thismay result in amplifier damage and wi// void the warranfy!

AMPLIFIER LOCATIONThe RUB/CON amplifier employs highly efficient circuitry, a custom-engineeredheat sink, and a unique Chassisink construction to maintain lower operatingtemperatures. Additional cooling may be required if the amplifier is located in atightly confined area or when driving especially low impedance loads at extremelyhigh levels.

When mounting the amplifier, it should be securely mounted to either a panel inthe vehicle or an amp board or rack that is securely mounted to the vehicle. Themounting location should be either in the passenger compartment or in the trunkof the vehicle, away from moisture, stray or moving objects, and major electricalcomponents. To provide adequate ventilation, mount the amplifier so that thereare at least two inches of freely circulating air above and to the sides of it.

MOUNTING THE AMPLIFIERa. Using the amplifier as a template, mark the holes on the mounting surface.b. Remove the amplifier and drill the holes for the mounting screws.C. Secure the amplifier to the mounting surface using the supplied hardware.

INSTALLATION STEP 5 1

The input level controls are located on the front of the amplifier. This is a uniquedual-stage circuit that adjusts both level and gain. This topology maintains betterS/N Ratio even when using sources with minimal output.

In the ideal situation, all components in the audio system reach maximumundistorted output at the same time. If you send a distorted signal to an amplifier,it is simply going to amplify distorted information. The same holds true if anoutboard processor or crossover begins to distort before you have maximumoutput from the amplifier. By setting all components to reach clipping at the sametime, you can maximize the output of your system. For your RUBICON amplifier,follow these steps for setting the input levels:

1. Turn the amplifier’s input levels to minimum position (counter-clockwise)2. Set the source unit volume to approximately 314 of full volume.3. While playing dynamic source material, slowly increase the amplifiers’ input

level until a near maximum undistorted level is heard in the system.

Once the amplifier is installed and the proper levels set,position, and secure it using the supplied hardware.
