Figure 7 - Three-Way Control Meanings

Here is a list of the controls for a single channel of the 24CX-3.

•Input Level: This lets you adjust the overall level of the channel. By turning this level up or down, you can adjust the volume of all speakers for a single channel simultaneously.

•Input Mute: Pressing this button mutes the input to the channel.

•Low Output Level: This lets you set the low-frequency output of the channel.

•Low Output Mute: This button mutes the low output of the channel.

•Mid Output Level: This lets you set the mid-frequency output of the channel.

•Mid Output Phase: Pressing this button reverses the phase of the mid output.

•Mid Output Mute: This button mutes the mid output of the channel.

•High Output Level: This lets you set the high-frequency output of the channel.

•High Output Phase: Pressing this button reverses the phase of the high output.

•High Output Mute: This button mutes the high output of the channel.

•Low/Mid Crossover Frequency: This lets you set the crossover frequency for the low- to-mid crossover point.

•Mid/High Crossover Frequency: This lets you set the crossover frequency for the mid- to-high crossover point.

Adjusting the Crossover Frequencies

With the amplifiers off or turned all the way down, set the crossover frequencies. Usually speaker manufacturers recommend suitable crossover points for their products. It is very important that the correct crossover frequencies are set before the system is used because improper crossover frequency settings can damage speaker components even at very low sound levels. If your unit has range switches (24CX-2 or 24CX-4), make sure they are in the correct positions for the desired frequencies.
