AEA - TRP - The AEA Ribbon Mic Preamplifier is an ultra high-gain and impedance, minimal-path FET mic pre designed by Fred Forssell. This low-noise two-channel preamp is for ribbon, moving coil, and tube microphones that do not use or want phantom power. This allows for improvements in minimal path circuitry and also rids the unit of phantom-power blocking capacitors. Zener diodes on the input protect the input stage if external phantom power is applied.

API 3124+ - A compact, versatile 1 rack-space unit with the same mic preamp circuitry that is used in all API consoles. It utilizes the E-115 K mic input transformer and the same output transformer that is used in all API equalizers. All four mic inputs of the 3124+ are powered by an internal 48 volt phantom power supply, front panel switchable for each channel. Also provided is a front panel 20dB pad switch that affects both the Mic and Line in.

API 3124MB+ - The M+ adds a complete 4x2 stereo mixer to the 3124. Also provided is a post fader Aux send and a stereo Aux return. With the re-design of the 3124 and the 3124M, API brought the phantom power switch to the front, added a polarity switch, added a transformer balanced stereo output option, added a little color, then Jeff wanted to call them the 3124 Plus and the 3124M Plus. ..So, be it...The circuit is still the original 312 mic pre-amp card, with all of the stuff hooked up for you. ..Many have tried to copy it, but it still wins the shoot outs!!!

ATI 8MX2 - The 8MX2 is an essential companion for any of todays digital multitrack systems. It offers 8 of the proprietary ATI High Voltage mic-preamps in a single rack space, and a stereo mix buss with full monitoring capabilities.

The QSP 4 channel mic preamp is made with real Class A discrete amplification and high end audio transformers just like the vintage classics of the past. But it does not carry the vintage price tag. The QSP has a stunning sound which you will immediately notice and owning a unit means never having to doubt your preamplifier again.

Buzz Audio - SSA 1.1 - The SSA-1.1 delivers a vibrant high definition signal path - users can expect excellent top end clarity and tight bass punch at a very affordable price. The SSA is great for all recording tasks leaving the signal clean and "in tact" so you can add you own flavour later in the mixing process - sounds sensible to us!

Buzz Audio- MA2.2 - The MA-2.2 has a transformerless input stage designed to minimize frequency response anomalies caused by reactive loading of the connected microphone. All gain stages utilize our own discrete transistor True Class A differential amplifiers (the BE40) to provide an amazingly wide bandwidth and fast slew rate. In fact, the internal frequency response of the MA-2.2 extends beyond 1,000,000Hz - even at full gain! (Passive filtering at the input of the MA-2.2 to limit the response to 250kHz prevents amplification of unwanted radio frequencies).
