The power amplifiers have a high-impedance direct input and an input port (edge connector) to accept one plug-in module. Module selection is determined by application among the TOA plug-in modules. The power amplifiers have a low-cut switch for a cutoff frequency of 60 Hz, and an input-level switch for input sensitivity of 1V (0 dBV) or 100mV (­20 dBV). Output terminals provide connections for 4-ohm and 8-ohm speakers, plus 25-volt and 70-volt speaker distribution outlets. With plug-in modules, the power amplifiers may be used as a PA amplifier. The power amplifiers can be rack mounted by using optional rack mounting bracket MB-25B(P-906MK2, P-912MK2) and MB-35B(P-924MK2). The optional perforated panel PF-511 provides suitable ventilation, finished in color to match the power amplifiers. Features 1. Wide frequency response : 20 ~ 20,000 Hz ± 1 dB 2. Low distortion and noise level 3. Excellent output regulation 4. A full range of plug-in modules 5. Self-protecting circuitry design 6. Varied output impedances : 4 ohms, 8 ohms, 25 and 70 volts 7. Input level switch (selectable 1000 mV/100 mV) 8. Portable or rack mounting type ­2­ Nomenclature Front Panel P-906MK2, P-912MK2 P-924MK2 Power Switch Applies line power.
