[. . . ] Negative Earth Mains Supply (rack units) The power supply unit is a universal input type therefore no mains operating voltage setting is required. The mains switch on the front panel of the 3U and 7U rack units is non-illuminating. The CH (chassis) and 0V Link should be connected or instability may result. User Guide Issue 3 Page 3 1081 Channel Amplifier Phantom Power Mains Fuse (rack units) The mains fuse is located in the IEC mains input connector on the rear of the 3U and 7U rack units. Secondary Protection Fuses (rack units) Secondary protection fuses for the 24V and 48V supplies are located behind the front panel on the power supply filter PCB SZN825-058 in both 3U and 7U rack units. DC Power Supply Indicators (rack units) The red LED on the front panel of both 3U and 7U rack units indicates +24V power healthy when illuminated. The green LED on the front panel of both 3U and 7U rack units indicates +48V power healthy when illuminated. Phantom Power Phantom power can be supplied to each module by pressing the phantom power switch on the front panel of the 3U or 7U rack. The LED in the switch will illuminate confirming that phantom power is supplied. Output Level Control Each channel has an independent Output Level Control. This control allows the input and EQ to operate at a higher level and then for the signal to be returned to a normal operating level at the output. The output is 10dB down with the control in the mid-position. User Guide Issue 3 Page 4 1081 Channel Amplifier Amplifier Controls Amplifier Controls dB 70 60 80 20 10 0 +10 H. F.
