Page 7: Tandem Mode
Bridge mono mode is used to deliver increased power to the loudspeakers. Using the MA1.3s in bridge mode reduces the number of channels from two to one. The nominal impedance of the load must be more than 3 ohms. Set the Link/bridge switches to the “ON”... -
Page 8: Installation
Your amplifier uses a forced air cooling system to maintain a low and even operating temperature. All fan cooled MARTIN AUDIO MA series amplifiers have front to rear cooling. Never try to reverse the direction of airflow, as the amplifier needs a pressure chamber between the fans and the internal heat sink and this only operates in one direction of the airflow. -
Page 9: Denmark
Danish safety regulation only permits the use of an 8A main fuse. As the MA 1.3s uses an internal primary mains fuse of 15A, the MA1.3s must be equipped with an industrial mains connector rated for 16A or above, or as an alternative it can be hard wired to a 16A capacity circuit and breaker. -

Page 13: Protection Features
Some manufacturers of loudspeaker processors do not recommend the use of clip limiters in amplifiers, as it can affect the tracking of the processor's limiters. If the amplifier is being used without any external limiting, Martin Audio recommend leaving the clip limiters switched "ON" (button depressed). -
Page 14: Short Circuit Protection
In the unlikely event of on a non-user rectifiable fault, return the amplifier to your supplier or an approved service centre.
