Figure 4: 6176 Rear Panel
Input/Output
Standard XLR input and output connectors are provided on the rear panel. Pin 2 is wired
positive (hot) on the LINE and MIC INPUTS. Pin 2 is positive on the 610B LINE
OUTPUT when the front panel Polarity toggle switch is down (IN ∅). Pin 3 is positive
on the 610B LINE OUTPUT when the front panel Polarity switch is up (OUT ∅).
1176LN Input Loading
The 1176LN Input Loading switch is located to the right of the LINE INPUT XLR.
When the button is pushed in, the input impedance will be 600 ohms, typical of older
vintage gear. When the button is out, the impedance will be 15K ohms. In some situations
you may perceive a “brighter” tone by using the 15K ohm position.
AC Power
The 6176 uses a standard, detachable IEC power cable.
Fuse/Mains
The AC power fuse is located in the AC power connector block. Remove the power cord
before checking or changing the fuse.
A 400 mA time delay (slow blow) fuse is required for operation at 115 V.
A 200 mA time delay (slow blow) fuse is required for operation at 230 V.
Voltage Select
The 6176 can operate at 115 V or 230 V. To change the mode, wait 5 minutes after power
down, unplug the AC power cord from the rear chassis. Remove the top cover. As
shown below, there is a connector that can be plugged in to one location or another
location to configure the unit for 115V or 230V operation. This figure shows the unit
configured for 230V operation. The connector can be identified by it’s wire colors;
Black, Blue, White, Orange. This connector should be plugged into location H8 for 230V
operation and location H6 for 115V operation. The connector is part of the wiring that
comes from the power transformer located at rear center of the 6176. When changing
operating voltage, fuse value must be changed as well. Make sure the 6176 is properly
set for the voltage in your area before applying AC power to unit!
