AC Input
The AC Input cable is connected to a standard IEC type input. The power supply will automatically
adjust from 90 VAC to 250 VAC, and works with 50 or 60 Hz.
Mains Power Switch
The Mains Power Switch is located above the AC inlet. It is an illuminated red type switch.
Fuses
There are no user serviceable fuses inside the unit. Your 1350 amplifier contains a 10A fuse which is
part of the power supply module. It is not user serviceable. In the event of a clear fuse failure or a
total lack of amplifier power up of the please contact your dealer or service center for assistance.
Fan
The DNA 800 has passive cooling and no fan is required
Amplifier Output Jacks
The Amplifier Output Jacks available on 1350 are configured as two NL4 type jacks (main), and one
1/4 inch phone jack for (emergency use).
Use the NL4 jacks for normal operation. The main speaker jacks are wired +1 and +2 together and -
1 and -2 together. The unit will accept both the NL2 or NL4 type cable connections. The
configuration is designed to give you the best connection possible your speaker cabinet. This will
give you the best quality sound, power output, and the deliver maximum available current to the
loudspeakers.
DI Output XLR Jack
The DI Output Jack is a balance line XLR type configured with pin (2) hot or plus. The signal is very
low noise and is studio quality. The output is protected to handle phantom power voltages if they are
accidently applied to the DI output. It is recommended that you turn off phantom voltage to this jack
before using the unit. The specialized THAT chip that drives this output is configured as an electronic
transformer and is fully balanced.
Ground lift
The ground the switch is located next to the DI output XLR. It allows you to reconfigure the ground
reference for pin one of the XLR. In the normal condition pin one of the output jack is connected
directly to the main chassis ground. When the ground is lifted by engaging the ground lift switch the
ground connection is removed from the pin(1) of the XLR. This is useful for eliminating or reducing
ground loops and unwanted hum and noise in the systems.
Auxiliary Input jacks
The AUX IN as an RCA input Jack set that features actively summed left and right inputs. It has six
dB of voltage gain. It provides a high-quality input that can take an IPad, auxiliary device or drum
machine and amplify it to the proper level to mix with the live bass guitar signal.
Foot switch control jack A
