XR-1 TWO-WAY CROSSOVER ...........................................

Figure 6: XR-1 crossover input option

The XR-1 two-way 24 dB/octave active crossover places one of the most

commonly used pro audio tools within one of the best power amplifiers on the market.

The XR-1 uses fixed-frequency filters and recessed controls for the ultimate in "set

and forget" crossover

flexibility, the nature of this product suggests using two fixed-frequency cascaded

butterworth response filters for each output. The low output includes an 18dB/oct.

20Hz hipass filter to reduce subsonic signal. The high output includes 360° of phase

control for driver alignment as well as two types of CD horn EQ. A single eight pin

SIP (single in-line package) resistor network selects the frequency for each filter.

Normally both the high-pass and low-pass filters are tuned to the same frequency, so

one value SIP is used for both filters. Installation of the resistor networks requires no

soldering - simply plug them in their respective 8 pin sockets as shown in figure 6.

variety of crossover/amplifier configurations (see figure 5). Mode 1 simply forwards

the high crossover output to amplifier channel one and the low output to channel two.

In Mode 1A, you can replace the high output with a full range signal by depressing

the Highpass/Full Range switch. Full range speaker cabinets are connected to channel

one while channel two drives additional subwoofers for those applications requiring

extended bass. The high level control becomes full range, while phase and CD Horn

EQ are removed from the audio path. Caution: never send full range audio into a

high frequency driver! To prevent a stray hand from inadvertently switching your

horn to full range, the button for this control is shipped seperately in the bag with the

resistor networks.
