The DHA DI_EQ is a fully balanced XLR DI with a 3 band plus Q sweep EQ designed to
interface between an instrument, Mic or effect at line level to a power amp, PC soundcard
or mixer. The DHA DI-EQ is totally hand build using a high quality PCB and point
to point methods, it is built to last.
The DHA DI-EQ is fitted with a PP3 9v battery but also has a 2.1mm external PSU adaptor
for use with a 9-12VDC @ 50mA external supply.
Important –the external supply must be negative centre, which means positive outer.
The external PSU and the battery both have reverse polarity protection so no harm
will be done if you get it wrong. The supply is connected automatically to the circuit
when you plug into the input jack, so don’t forget to unplug in when not in use or
an external power supply is connected or the battery will go flat! The led indicates
when the effect is on.
Level sets the output level of the Line out, this provides a wide range of clean
boost which can be used to overdrive amplifiers. There is a separate DI level.
The 3 position ground lift switch affects Pin 1 of the XLR connector and is there
to fix any possible earth loop issues. GND connects Pin 1 to ground, Float disconnects
Pin 1 from ground and Ploat connects Pin 1 to ground via a 10R resistor. There is
a DI level pot on the side of the pot.
The input and output jacks on the front of the pedal are connected together so that
an unaffected signal can be sent to an amp, other pedals, etc.
The 3 band EQ is active and provides a cut and boost of 15dB in each band. The Q
sweep adjusts the centre frequency of the Mid band and is used to find the “sweet
