MA 4 MULTICHANNEL AMPLIFIER Advanced Application - Fault Reporting If you wish to have an amplifier channel report a fault to a control system or back up amplifier, set it to Master. The Fault Flag is held high (+5 volts) during normal operation and goes low (passive pull down) when a fault occurs. For information about Fault Flag operation (applications and reported faults) see the Manual, page 3. Remote Level Control inputs are provided for each channel. The Rane VR 2 or any 10k to 100 kΩ potentiometer may be connected to these inputs. MADE IN U.S.A. RANE CORP.
