DESCRIPTION
73-style Mic Preamp
The top of the line stereo microphone preamplifier from Heritage Audio, there is no other current offering from any other
major brand giving as much, in terms of authenticity, quality of construction and sound.
The Heritage Audio DMA 73 is a true dual 3-stage 73-style mic preamp in a 1 rack unit format. Added to the accurate
vintage features, there are some key ones for covering all the needs of modern producers, engineers and musicians.
Employing only discrete circuitry and conventional, vintage-style components, the DMA 73 is a faithful 3-stage all Class
A 73 preamp. Custom styroflex and tantalum capacitors have been used throughout, no corners cut.
The DMA 73 is completely hand-made and hand-wired in our Madrid Spain facility, employing only traditional through
hole circuitry, just like it was done in the 70s. It indeed takes a massive amount of qualified labor to get one unit ready
for studio operation. The results are simply stunning.
Carnhill input transformers are hand wound at the Oxford factory exclusively for Heritage Audio, enclosed in vintage
correct green metal cases for the ultimate in detail nailing. The vintage character is indeed guaranteed and you won´t
find them in any other brand´s products.
The line mode allows for reamping prerecorded tracks and it is perfect for adding the magic vintage Class A mojo to
lifeless recordings. It indeed makes use of the mic input transformer.
The DI circuit is an all discrete Class A JFET circuit ahead of the microphone transformer, so none of the magic is
compromised.
Since its introduction in 2012, the Heritage Audio´s DI circuit has become a classic for recording bass guitar direct.
When looking to spend top dollar for the ultimate vintage 73 preamp experience, always keep the following in mind:
Transformers can make all the difference in the world.
The DMA 73 Transformers:
No 73 preamp is such without the correct transformers. Heritage Audio went a step further then competition. The output
transformer, the same used all along Heritage´s line of products, is a Carnhill gapped one made exclusively for us in the
St Ives factory. The input transformer, again exclusive to our company, is made in Carnhill´s Oxord factory, and has a big
impact on the extra mojo of the unit. It is the same one found in our higher end 80 Series modules and is one of the
main reasons for sonic differences in between the DMA 73 and the competitors.
When looking for an exclusive sound, do not settle for non-exclusive transformers.
