2) On the inside of the connector panel, you'll find a PC board and two connectors. The two position connector will have a cable assembly
plugged into it with the wires leading to the passive crossover. The four position connector will be empty. Circled in Figure 2.
3) Follow the wires to the passive crossover. Unplug the two-wire cable assembly from the crossover network by squeezing the locking tabs
on either side. Circled in Figure 3.
4) On the other end of the crossover network will be a four-wire cable assembly with the wires leading from the network to the individual
components. Unplug this cable in the same manner. Indicated by arrow in Figure 3.
5) Plug this four pin connector into the four pin receptacle on the input connector panel. The connector is keyed and will only insert the cor-
rect way. Circled in Figure 4.
6) Neatly tie the unused two-conductor wire harness to the panel so it's available if it is ever desired to convert the loudspeaker back to fully
passive operation. Indicated by arrow in Figure 4.
7) Reinstall the input connector panel. Be careful not to over tighten the screws as you may strip the cabinet wood. Note that you can now
see the white connector through the window indicating that the loudspeaker is configured for bi-amplified use. Circled in Figure 5.
8) If you want to convert the loudspeaker back to fully passive operation, simply reverse these steps.

LIMITER CALIBRATION

You can use other signal processors with Renkus-Heinz loudspeakers, but in order to protect them from damage, you must do your best to
re-create the process Renkus-Heinz Engineering uses to set up the limiters. The following procedure is as close as you can get without ac-
cess to the specialized equipment we use at the factory.
You will need a sine wave generator (or a test CD with sine waves of various frequencies) and a volt meter.
1) Set up your system's gain structure.
2) Disconnect the loudspeakers from the amplifier. Do not set
the limiters with the loudspeakers connected - you will damage
the loudspeakers. This damage is not covered by our warranty!
3) Feed a sine wave signal into the amplifier. Use a frequency in
the lower part of the driver's pass band: 60 Hz for subwoofers,
200 Hz for lows and fully passive speakers, 1 kHz for mid-
ranges or mid-highs and 2.5 kHz for compression drivers.
4) Connect the volt meter to the amplifier outputs.
5) Check Table 2 for the maximum RMS voltage that should
reach the loudspeaker based on its Program power rating.
Raise the level of the signal generator until the volt meter reads
two or three volts above the specified voltage.
6) Reduce the threshold control of the limiter until the voltmeter
reading is at or below the maximum from Table 2.
