BEFORE YOU START5Power Terminals ”+” Connect to the vehicle’s positive 12V supply (+12V DC) ”-” Connect to the vehicle’s ground (-12V DC) ”R” Connect to the head unit’s remote turn on leads. ”D/R” Delayed Remote output. Connect to all the amplifiers following the CX4R.This will delay the turn on of these units by 2 seconds after the system is powered up. 6 Remote Low Pass Level Control Docking port for the jack of the supplied CXR Remote control.This gives you the possibility to adjust your Low Pass Level on dash. 7-10 Output Level Controls These allow you to adjust the output levels of all 4 different channels. Because not all speakers (tweeters, woofers) have the same sensitivity, the output level has to be adjusted, so the overall volume will be the same for all speakers. 11 Band Pass Mono/Stereo Switch This switch gives you the opportunity to set the Band Pass output in a mono or stereo mode.This can be very usefull if you use the Band Pass output for your rearfill or as a centerchannel. 12 Low Pass Phase Switch This switch allows you to turn the phase of the Low Pass channel 0°, 90° or 180°.This option can be helpfull when your subwoofers are places further away as the rest of your speakers.This creates significant phase differences which make you hardly hear any low-reproduction in the driversseat. By turning the phase of the low pass signal, you can correct the sound level of your Low Pass. 13 Low Pass Mono/Stereo Switch With this switch you can choose whether to have your subwoofer(s) (Low Pass) play in mono or stereo mode.We advice you to always let your woofers play in mono-mode, especially when there is more than one woofer in an enclosure. 14 Band Pass/High Pass Selector In some installations two High Pass outputs are desirable.This selectorswitch enables you to make a second High Pass output from the third channel. Specifications CX4R Frequency response 10Hz to 30KHz ±1dB T.H.D. 0.02% Signal to noise ratio >100dB Channel separation >80dB Input level -12dB to 12dB (7V to 0.2V) Input impedance 20KΩ Maximum output level 15V Output impedance 50Ω Balanced Crossover slope 24dB/Oct Fuse rating 1A Dimensions W x L x H (mm) 260 x 160 x 38 (mm) Features CX4R (See illustration on the inside cover) 1 Input Docking ports for the RCA connectors arriving from the source unit’s output. If you choose for a two channel input, connect the RCA’s to the docking- ports 1A, and switch the input-selector-switch(1C) to the single position. If you decide to use the four channel input option, connect both the RCA dockingports 1A and 1B, and switch the input-selector-switch(1C) to the dual position. In case you use a four channel input, you can still use the fader- adjustment from your headunit. 2 Input Level Control This Input sensitivity control allows you to adjust the input sensitivity to the output of your source unit, in order to get a maximal signal transmission. 3 Subsonic filter On/Off Switch This switch allows you to switch on or off the Subsonic filter.The Subsonic filter filters the lowest (non musical) frequencies out, which will make your speakers (especially your woofers) sound more naturally. 4 Subsonic Frequency Adjustment The subsonic frequency adjustment allows you to adjust the frequency which is filtered by the subsonic filter. By adjusting this frequency (between 10-40Hz) to the frequency-range of your subwoofer, you can get an optimal result.

SPECIFICATIONS AND FEATURES• Second, the -12V ground terminal must be connected.The -12V ground is the second slot(B) from the left of the powerconnector.This cable has to be faste- ned securely to the chassis of the vehicle with the same gauge cable as the posi- tive cable (the same amount of power has to run through it). Preferrably you should have the same ground connection for your entire system. Ensure that all paint, undercoating or any other insulation is removed from the area where you want to make your ground connection to.

• Third to connect is your remote turn-on.The R (remote turn on) is the third slot(C) from the left of the powerconnector. Many radio-cassette and CD-players have an output terminal for connection of the Remote turn on. If you don’t have such an output, a separate switch must be installed to control your remote on/off functions.

• The last terminal to connect is your Delayed Remote output.The D/R (Delayed Remote output is the first slot (D) from the right of your powerconnector.The delayed remote output should be connected to all the amplifiers and other equipment following the CX4R, so they can be started with a 2 seconds delay. Signal input The next to connect is your signal input. Choose the correct length and style of RCA patch cables for your needs. Better RCA’s, such as the ones from the Caliber CL 600 and CL 800 Get Connected Series, have gold-plated connectors and multiple layers of shielding for better noise rejection. These twisted cables give a better result in combination with the balanced outputs. (Consult your offi- cial Caliber dealer about these cables and RCA’s). Be extra careful when running your RCA patch cables. Car environments are notorious for poorly insulated wires.This means that hiss, engine noise and fan noise can easily be picked up trough RCA cables, if ran incorrectly.As a precau- tion, avoid placing your RCA’s near large wire looms and electronic fans when- ever possible. Connect the patch cables to the RCA output of your source unit. Run the RCA cables to the location of the CX4R, and connect them to the input RCA con- nectors of the CX4R. Be sure to connect the right channel to the right channel, and the left to the left. (In an audio system the right always has red RCA con- nectors, and the left RCA connectors are white or black). Signal output Once you have connected the inputs, it is time to connect the outputs. Be care- ful to connect, via RCA patch cables, the correct output to the correct amplifier. Ta ke good care in the balance of your signal (Right to right, and left to left). Now that you have connected all your signal and power cables, it is time to con- nect your battery again, and place the 1A fuse in the fuseholder.

MOUNTING AND CONNECTING YOUR CX4R

15-20 Modulair Resistor Units These 16-pins modulair resistor units are what it is all about with the CX4R. They allow you to create a really personal sound, which is especially tuned for your installation. By changing the resistor value of these units, you can determine your own crossoverfrequency per channel.The sequence of these resistor units is shown in the graphics below them. So, module 1 (15) is for the High Pass side of your Band Pass channel, and module 2 (16) is for the Low Pass side of your Band Pass Channel, and so on. By giving all the modules your own resistor value (and thus their own bandwidth) you can tune your installation to perfection. How you can calculate the resistor values for each frequency is demonstrated in a separate chapter. 21 Clipping LED’s These clipping LED’s will warn you when an output is clipping.When they lit up continously the output is clipping, and you should immediatly adjust the outputlevel, or you will damage your speakers.When these LED’s start to flicker, the output is almost clipping.This is a warning sign for you to take extra care to the output level. 22 Outputs Docking ports for the RCA cables which lead to the various amplifiers. Mounting your CX4R Find a steady, secure area to mount your CX4R. Be sure it is accessible, but not in an area where the adjustments may be bumped by accident. Use the chassis of the CX4R as a template and mark the locations of the mounting holes.Predrill the moun- ting holes using a 2,5 mm diameter drill bit and use the screws supplied with your CX4R to fasten your 4-way crossover. Make sure the screws are tightened securely. Getting your power started

• First, the +12V terminal is connected.The +12V termi- nal is the first slot(A) from the left of the powercon- nector. Use the same +12V source as you are using for your amplifiers, in order to avoid picking up noise due to voltage differences. Don’t forget to add an inline fuseholder holding a 1A fuse at the beginning of the powercable for the CXQ20.This to protect both your vehicle and audiosystem in case of a short.

A B C D screwdriverWe will give you three examples of how you can set up a system.Take good care in the position of the various switches. In all the system set-ups we show you, the subsonicfilter is in its “on” position. Crossoverpoints (resistor unit values) Determing the best crossoverpoints (

resistor unit values) for your speakers is critical.The size of the speakers, their powerhandling caracteristics and frequen- cy range have to be taken into consideration.Also the location of the speakers has to be evaluated before the best crossoverpoints can be choosen. A good ear, and proberbly some advice from your official Caliber dealer can help you a lot when you are adjusting your crossoverfrequencies. How to calculate the correct resistor value for a desired crossover-frequency.

R (Kilo-Ohm) = Frequency (Hz) Example: Desired crossover-frequency = 72Hz

R (Kilo-Ohm) = = 100KΩ 72 Hz To make your own value resistor units, you will need a 16-pins module and the required resistors to come to the calculated resistor unit value. Given resistorvalues are the standard values of the E12 resistorseries.
