Operating Manual - FTX-1001, FTX-1501, FTX-2001, CFT-1800 Power Amplifier

8.INPUT OPTIONS

Input option panels are available to provide built-in features such as a stereo compressor-limiter, a mic and line mixer, a crossover for bi-amplified systems, and input transformers for signal isolation. In addition to the FTX amplifiers, input options can be installed on MFA High-Power amps, the CFT-1800 convection cooled amp, and P70 series 70 volt amps. A brief description of currently stocked input op- tions follows. Consult your dealer for detailed information on input options, or call the factory at 800-828-6308.

8.1Input Isolation Transformer (not shown)

The input transformer provides complete electrical isolation from the amplifier and its signal source to eliminate any ground-in- duced hum noise. The transformer input also further reduces any com- mon-mode noise and radio frequency interference. The transformer option is factory installed in a standard input panel and does not change the operation of any switches or controls.

8.2Peak Limiter/Compressor

The limiter input option provides peak signal limiting from excessive input levels for speaker protection and overall level control. Separate limiter threshold controls, limit indicator LED’s and limit on/ off switches are provided on each channel allowing fully discrete ste- reo limiting operation.

8.3Two-Way Crossover

The crossover input option provides fixed-frequency 24 dB/ octave high-pass and low pass filters allowing the two amplifier chan- nels to operate bi-amped, full range with low out, both channels low out, or bridged low out. Auxiliary low and high outputs are available for connecting additional amplifiers. Included with the crossover in- put option are single in-line package (SIP) resistor networks which al- low preselection between standard crossover frequencies of 160Hz, 500Hz, 750Hz, 1.2KHz, and 1.6KHz. 360° of phase control is pro- vided for proper acoustical alignment of high and low frequency driv- ers. Selectable constant directivity horn EQ is provided for both small and large horn designs.

8.4Six Input Mic-Line Mixer

The mixer input option provides four high-impedance line in- puts and two balanced low-impedance microphone inputs, each with its own level control. A switchable 200 Hz high-pass filter is provided on the mic inputs to reduce unwanted low frequency noise. An internal jumper allows selection of 15 Volt phantom power applied to the mic inputs for use with condenser mics. The option has a master level con- trol and selectable stereo, mono and bridging modes. Insert Points are available for patching external processing into the left and right chan- nels.
