Installation Precaution
Mono Operation
The P-75D, P-150D and P-300D are designed to be used as mono amplifiers by placing their mode
switches in mono positions. In the mono mode total speaker impedance should not be lower than 8
ohms.
Source Resistance and Damping Factor vs. Length and Size of Output
Leads
The following figure indicates that a 100 foot length of # 14 AWG annealed copper wire (two
conductor) yields a combined amplifier/cable source impedance of 0.5 ohms. A typical 8 ohms load
impedance is indicated, and this results in an effective damping factor of 15. (This damping factor is
less than the rated one of each model obtained with zero ohms cable resistance). Larger diameter
(lower wire gauge number) should be used for longer cable.
