Figure 4. CS50.4 amplifier in 4-channel (stereo) operation to drive front and rear full-range speakers. Figure 5. CS50.4 is set up for 3-channel operation to drive a set of full-range speakers and a subwoofer. Figure 6. CS50.4 used in bridged 2-channel mode to drive a set of components or subwoofers. Set crossovers according to application. APPLICATIONS – CS50.4 The CS50.4 can be set up for stereo 4-channel, 3-channel or bridged 2-channel operation, as shown in Figures 4 through 6. NOTE: For simplicity, Figures 4 through 6 do not show power, remote and input connections. NOTE: Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms. CONTROLS AND SETUP SPECIFICATIONS Declaration of Conformity SETTING THE CROSSOVER(S) Determine your system plans and set the crossover mode switch accordingly. If your system design does not include a subwoofer with the CS50.4, set the crossover mode to FLAT and skip to “Setting Input Sensitivity.” Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible. SETTING INPUT SENSITIVITY 1. Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise). 2. Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track. 3. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard.
