Page 16: Installation Precautions
Loop When a Y cord is used, shorten the wiring to minimize noise. A ground lift terminal is provided on the rear of the P-150M and P-300M. Removing the bar in the terminals lifts ground. Since the P-150M and P-300M are high power amplifiers, be careful with ventilation when they are installed. - Page 17 Mounting in an enclosed rack cabinet The P-150M and P-300M are mountable in a standard 19" rack. When mounting, insert a 1-unit-sized perforated panel between the units mounted, and place the same at the bottom of the rack. Be sure to mount a perforated panel larger than 1 unit size at the top of the rack.
- Page 18 All manuals and user guides at all-guides.com Installation Precaution 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.

All manuals and user guides at all-guides.com 25/70 Volt Distribution Systems A constant voltage distribution system is a method of connecting loudspeakers to an amplifier where the output voltage of the amplifier and the amount of power delivered to loudspeakers remain constant. - Page 20 All manuals and user guides at all-guides.com 25/70 Volt Distribution Systems Two important factors must be considered when setting up a constant voltage distribution system. 1. The rated power of an amplifier must be higher than the total power that the speakers receive. 2.
