This owners manual is written in easy english and uses a lot of drawings to simply the installation and use of the above amplifiers. Your DLS amplifiers must be installed correctly in order to work well. Install the amplifier yourself if you feel confident with our instructions and if you have the proper tools. [. . . ] In CA23 the high pass filter is designed as a subsonic filter variable from 15 Hz to 150 Hz. The filter can be switched off if you want to run the amplifier in full range mode. Low Pass Filter LPF 80Hz 200Hz 50Hz 500Hz LPF 80Hz 200Hz 50Hz 500Hz Off On Off 24 dB 12dB Phase control CA31 & CA51 The phase control on CA31 & CA51 can be set continuously from 0 - 180 degrees. This is very useful when you want to adjust the bass sound for best front stage image. Start on 0 and turn the control slowly clockwise until you experience that the bass sound is coming from the front. If you dont get the result you want, also try to PHASE phase reverse the subwoofer connections and make 0 180 a new adjustment. 6 CA22 CA23 The LPF ( low pass filter ) mostly used for subwoofers. In the CA23 amplifier you can select between two different slopes, 12 dB/ octave or 24 dB/ octave. Choose the slope and the setting that sounds best in your car. Crossovers of CA31, CA41 & CA51 CA22, 23, 31, 41 & 51 CA-51 The CA41 is a four channel amplifier. It is mostly used with a front system connected to channels C/ D and a subwoofer connected to channel A/B. Please observe the proper settings of the channel A/B LPF multiplier switch and of the channel C/D HPF multiplier switch. The CA41 can also be used to feed a 2­way front system with active crossovers between midbasses and tweeters. This is described in a speaker wiring and filter setting example on page 11. LPF Multiply 80/800Hz 200/2(k)Hz The CA31 is a three channel amplifier. The C channel is for subwoofers and has a subsonic filter, a variable low pass filter, 50-120 Hz, and a phase control variable from 0 - 180 degrees. The subsonic filter can be switched IN-OUT and has a fixed frequency of 25 Hz. Off On 50/500Hz 500/5(k)Hz x1 x10 HPF Multiply 50/500Hz 220/2(k)Hz Off On 15/150Hz 500/5(k)Hz x1 x10 Channel A/B is equipped very much like the CA22 and CA23, however the LPF has a multiplier. Thus the frequency range of the LPF can be varied from 50 Hz ­ 500 Hz in the x1 position or 500 Hz ­ 5 kHz in the x10 position. This way we can use this amplifier to feed a 2-way system, where the midbasses are feed from 80 Hz ­ 4 kHz. The tweeters connected to channel C/D , operate from 4 kHz upwards using the HPF in multiplier position x 10 150 Hz ­ 5 kHz. The CA51 is a five channel amplifier. On channel A/B, C/D the filter configuration is exactly the same as for CA41. Channel E is a subwoofer mono channel with a lowpass filter adjustable from 60 to 120 Hz. The CA51 has also a phase control variable from 0 - 180 degrees. 7 CA22, 23 Speaker wiring CA 22 & CA23 Two fullrange speakers to CA22 or CA23 One subwoofer connected in bridge mode to CA22 or CA23 Filter settings HPF 50Hz 220Hz Subsonic 40Hz 100Hz NOTE!Filter settings 15Hz 500Hz 15Hz 150Hz Off On Off On HPF 50Hz 220Hz Subsonic 40Hz 100Hz CA22 CA23 With the HPF-filter in OFF position the amplifier allows the speakers to play fullrange. If you for some reason want to limit the low bass reproduction switch on the HPF-filter. [. . . ] If speakers don´t play at all, one or both speaker wires may be disconnected. 13 CA22, 23, 31, 41 & 51 Professional Tip: NOISE PROBLEMS WHINING NOISE VARYING WITH ENGINE REVOLUTIONS: Do this: 1. Check quality of earth strap connection from battery negative terminal to chassis. Test this by laying a new cable over the seats and reconnecting to the amplifier. If the noise does not return, reroute original cable away from source of interference. [. . . ]
