XO47
Features
- Active two way cinema analog crossover
- Filters are 24dB/octave Linkwitz Riley
- Selectable Three crossover frequencies 250Hz, 500Hz, 1.2KHz
- Emergency (EMG) switching for feeding the center channel signal to left and right channels
- Summed LCR signal for Subwoofer bass management.
The Pulz XO47 is a dedicated active two way cinema analog crossover designed to maximize the performance of the Pulz cinema speaker systems. It has 4 balanced inputs and 7 balanced outputs for the Left, Centre and Right screen channels and one Subwoofer channel in a 1U rack space chassis.
The filters are 24dB/octave Linkwitz Riley configured with low noise OPAMPS and close tolerance components. The additional features include subsonic roll-off, delays, CD horn EQ and screen loss equalisation. Externally accessible thumbwheel switches are provided for HF, LF and BM level settings.
The Pulz XO47 can be configured for the Pulz EM1/EM3/ESM4/ESM5/ESM6/ESM7/WM2 cinema speaker systems in Biamp mode.
The Pulz XO47 also offers optional facility of bass management.
The Pulz XO47 has emergency (EMG) switching. In situations when center channel amp or speaker fails, the center channel signal can be fed to Left and Right channels by activating the EMG switch. Hence, maintaining the Center channel signal (dialog) audible via Left and Right channels to continue the running show without disruption.
A sturdy rack mountable chassis, built in robust DC power supply and Phoenix type input output terminals ensures long-term reliability in all types of cinema projection booths
