Please read this manual carefully before beginning any installation to prevent damage and postinstallation problems.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Civil Air Patrol Version Installation and Operator’s Manual Avoid installing the audio panel close to high current devices or systems with high-voltage pulse type outputs, such as DME or transponders. 2.3.3 Mounting Rack Installation Remove the unit from the mounting tray by unscrewing the 3/32" hex-head screw that is in the center of the unit. Use caution to avoid hitting the photo-detector lens.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Civil Air Patrol Version Installation and Operator’s Manual not eliminate all noise, particularly if the amplitude of noise is very high. There must be at least nominal aircraft voltage present at the bottom connector, pin 20, of the PMA7000M-S for the power supply to work in its designed regulation. Otherwise, it cannot adequately attenuate power line noise. Shielding can reduce or prevent radiated noise (i.e.
PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Civil Air Patrol Version Installation and Operator’s Manual 2.5.4 Power The PMA7000M-S-Series is compatible with both 14-and 28-Volt DC systems. A two- (2) Amp circuit breaker is required for 14 VDC installations, and a three- (3) Amp breaker for 28 VDC aircraft. Power and ground wires must be a twisted #18 AWG pair. Connect airframe power ground to J1 (bottom connector) Pin Z only. No dropping resistors are required. 2.5.
