• Route signal wires away from power and/or speaker cables.
• Use wire ties to dress wiring away from potential hazards.
Connections
For operation with standard (non-bridged) amplifiers: (Please refer to figure 2)
• Connect the output jacks on your preamplifier to the LEFT and RIGHT INPUT jacks on the DX-1.
• Connect the HIGH FREQUENCY OUTPUT jacks on the DX-1 to the high frequency input jacks on the amplifier driving the high frequency
portion of your stereo system.
• Connect the positive (+) LOW FREQUENCY OUTPUT jacks on the DX-1 to the low frequency input jacks on the amplifier driving the low
frequency portion of your stereo system.
• Plug the female end of the power cord into the AC POWER connector and plug the other end into the power source.
For two-way operation with dual bridged low frequency amplifiers (Caution: be certain that the low frequency amplifiers are compatible with bridg-
ing operation prior to connecting them; see
Bridged Low Frequency Amplification on page 5):
• Connect the output jacks on your preamplifier to the LEFT and RIGHT INPUT jacks on the DX-1.
• Connect the HIGH FREQUENCY OUTPUT jacks on the DX-1 to the high frequency input jacks on the amplifier driving the high frequency
portions of your loudspeaker systems.
• Connect the positive (+) LOW FREQUENCY OUTPUT CHANNEL A jack on the DX-1 to the Channel A input jack of the bridged amplifier dri-
ving the low frequency portion of your left channel loudspeaker.
• Connect the negative (–) LOW FREQUENCY OUTPUT CHANNEL A jack on the DX-1 to the Channel B input jack of the bridged amplifier
driving the low frequency portion of your left channel loudspeaker.
• Similarly, connect the positive (+) LOW FREQUENCY OUTPUT CHANNEL B jack on the DX-1 to the Channel A input jack of the bridged
amplifier driving the low frequency portion of your right channel loudspeaker.
• Finally, connect the negative (–) LOW FREQUENCY OUTPUT CHANNEL B jack on the DX-1 to the Channel B input jack of the bridged
amplifier driving the low frequency portion of your right channel loudspeaker.
• Connect the low frequency loudspeaker wires only to the red or positive (+) output terminals on the bridged amplifiers. Do not
connect anything to the black or negative (–) bridged amplifier terminals.
NOTE: The negative (–) LOW FREQUENCY OUTPUT jacks on the DX-1 are provided for maintaining the integrity of the polarity convention of the
loudspeaker for optimal response. Do not use these connections unless you know to which convention your loudspeakers and amplifiers conform.
Caution: Be absolutely certain that the high and low pass signal connections are routed to the correct amplifier(s). Incorrect connec-
tions may damage the loudspeaker system.
