• Dual99v500 mic pre kit uses 2 of our discrete 99v opamps (New +/-16v version) as a 2-stage gain path to provide 75dB of gain with ease. It is aimed at getting big but realistic vocals and acoustic instruments. With the impedance control 200ohm to 3k load it goes from dark and slow to airy and fast tone-wise. A centre detent at Z 600ohm is the best starting point.

Max Output = +26dbu @ 1khz into 600ohm Load & +28dBu @ 1khz into 10k load

Sound Samples I am not a big fan of samples because if you didn't hear the original instruments sound in the studio with your own ears then really you don't have a true point of reference to gauge the samples against. These samples are more to show the difference between the Dual99v500 and TG500.

All instruments recorded by Matt Redlich with no EQ or compression. Pres had Impedance left centred in the Z detent and no HPF. Pres were used in their cleanest mode with output trim not pulled to allow for gain overdrive.

Drums - Colin O'Reilly. Acoustic Guitar - Ben Stewart. Electric Guitar - Greg Cathcart.

Drum kit -> Pearl Masters Mahogany Classic 4 piece kit with Zildjian New Beat hats and a Zanki ridewith mostly Remo single ply heads.
