Product Information
 

Updated BA22 channel mic pre rack kit. Each channel can use 1 discrete opamp as a 1 stage gain path to provide 60dB of gain. The most popular BA2 configurations are JLM14 input transformer + JLM99v opamp for big smooth fat and clean sounding. The 2nd most popular is VTX + JLM99v opamp for a bit more coloured in a Neve 1073 kind of way.

Updates

  • Impedance control now has centre detent and is the best starting point.
  • Quicker and easier to build as most of our Baby Animal kits wiring is done with 10wire ribbon cable that are provided made up so no shielded cable and only a few single wire connections are needed.
  • No mains wiring or power supply to build as it runs on our 48v prebuilt SMPS that can run on 85vac to 250vac without switching. Power supply takes standard IEC power lead so is easy to plug into power anywhere in the world.
  • Di kits used now are the new Fet DI kit which is simpler to build and mount to the front panel easily with a strong Cliff S4 jack.

Feature for each channel 

  • Balanced Neutrik Gold XLR in rear panel which is switched to 1meg Fet DI input when jack plugged in.
  • 48v phantom power switch with red LED indicator for rack XLR in.
  • (All below features work for XLR and DI input.)
  • Phase switch.
  • 20dB pad switch.
  • Input transformer.
  • Variable Impedance 200ohm to 3k with centre detent at starting Z point.
  • Gain Control 20dB to 60dB
  • Huge output transformer option.
  • Balanced Neutrik gold XLR out on rear panel .

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 TG500 and Dual99v500 (same as Daul99v rack kit version built on BAD and similair to BA kit fitted with VTX and 99v except BA runs out of gain at 60dB).

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 there cleanest mode with output trim not pulled to allow for gain overdrive.

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

BA2 Build thread here

BAN Build thread here

BAN kit comes with 2 x BC550C and 1 x OPA2604AP input opamp but you need to select a output opamp and optional output transformer.

For BAN kit instead of BA kit you need to select input transformer as BAN and then a opamp and output transformer option like a normal BA kit.
