6. CONNECTION OF Reference 200A
The following examples shows some normal ways of connecting this 4-channel amplifier. The drawings
shows normal level and filter settings. The four channels are divided in two amplifier blocks with the
signal input to the right, then the level control, the filter and to the left the speaker terminals.
Reference 200A can be connected in many different ways:
1. As a stereo amplifier with one front and one rear system.
These can be of coaxial, 2-way or 3-way type. Two speaker systems can also be connected in parallel.
For example one pair in the back doors and one pair in the hat rack connected to the rear output on the
amplifier.
2. One front (and if you want also a rear system) in the doors or dashboard, and one subwoofer in mono
bridge mode to the amplifier rear output.
3. In multimode with a front stereo system connected to front output, and a rear stereo system to rear
output together with a subwoofer in mono bridge mode using passive crossovers.
4. A stereo system connected in mono bridge mode on both front and rear output. This gives a higher
output to the speakers.
5. A 3-way system can be connected with active crossover between woofers and mid/tweeters.
6.1 In stereo with one front and
one rear speaker system.
You can use all DLS coaxial, 2-way or 3-way
speaker systems in this example. Speaker
impedance must be 4 ohm.
If the head unit has only one pre out a Y-cable
must be used.
