II Morrow SL-10 Audio Panel

Salem, OR-- II Morrow has teamed with PS Engineering, Inc., to offer four new Audio Selector Panels for general aviation aircraft. The 4 Models include: the SL10 a standard audio selector panel with six place intercom; the SL10M with intercom and built in marker beacon; the SL10-S with intercom and hi-fi stereo; and the SL10M-S including intercom, hi-fi stereo, and marker beacon. PS Engineering audio products are world renowned for their superior performance and reliability and they are the pilot preferred choice in audio panels. The same quality and innovative features are included in the new II Morrow Slimline audio panels.

The Apollo SL10 products are loaded with features and functionality for the pilot, crew, and passengers. Each of the SL10 models can be connected to as many as 3 transceivers and 6 receivers. Through the use of the intuitive front panel controls the pilot and co-pilot can quickly and easily switch between Comm 1 and Comm 2, with the added benefit of selecting any or all receivers. An optional remote push button switch can be installed on the yoke to provide the pilot with another convenient means of switching between Comm 1 and Comm 2. The voice activated intercom offers the utmost in flexibility with pilot, co-pilot and passenger channels. The pilot can select between ISO, All, and Crew. In the ISO mode the pilot remains connected to the audio panel with the crew and 4 passengers connected to their own VOX intercom. The ALL mode connects pilot, crew and passengers to a party line, and the CREW mode can isolate the pilot and co-pilot from the passengers. The front panel controls are backlit with an automatic dimming circuit for easy night operation.

The new Apollo SL10 Audio Selector Panels are an addition to II Morrow's popular line of Slimline products. Other Apollo Slimline models include the SL40 VHF Comm Transceiver, the SL50 GPS, and the SL60 GPS/Comm. All of the II Morrow Slimline products are TSO approved.
