Automatic output power control. The power control maintains the output power to a
specific level and is independent of temperature and voltage changes.
Twelve segment bar graph for display of peak transmitter modulation. The five highest
LED’s (100% to 250%) have a “peak–hold” feature which will display instantaneous
peak value for one second, a valuable feature when dealing with pre–emphasized
program audio.
Automatic switching capability by addition of Model ATS–15E Transmitter Switcher
Accessory plug for external DC power, remote control, remote metering, and other
functions
Low power consumption for operation on AC, solar cell, battery, or other
single–polarity DC source. (Marti Model UPS–12 Uninterruptible Power System).
Terminal strip for a balanced 600 ohm audio input, BNC jack for unbalanced audio,
Sub 1, and Sub 2 inputs.
The Marti STL–10A system derives its excellence from Marti’s experience in supplying thousands of such systems
world–wide over the past thirty years. This equipment incorporates state–of–the–art technology and is manufactured
in modern, efficient facilities under high quality–control standards.
