24. Output Connectors This is a five-position barrier strip for connection of speaker loads. Each terminal accepts bare wire from 22 AWG to 10 AWG, or spade lugs sized for the same range of conductors. Terminals are provided for 4 ohm low-impedance loads or 25, 70 and 100 Volt high-impedance loads. All outputs with the exception of the 4 ohm output are transformer isolated. LOW IMPEDANCE To connect a speaker directly, connect the lower GND terminal to the negative post of your speaker, and connect the 4 ohm terminal to the positive post. Make sure that your average speaker ...

1. SAFETY INSTRUCTIONS 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than ...

5. THERMAL CONSIDERATIONS The power amplifier within the unit is convection cooled rather than fan cooled. Heat is drawn away from the amplifier by the heatsink and radiated through the cooling vents in the top and bottom cover. When installing, be sure to allow sufficient air space around the top and rear of the amplifier to allow adequate cooling for the heatsink. Leave at least one rack space above and below, and at least 6 inches behind the chassis to allow proper ventilation. If the amplifier should overheat, a thermal switch turns off the power amplifier, allowing t ...
