Warm Audio WA 412 4 Channel Discrete Microphone Preamplifier And Instrument DI Fully discrete, transformer coupled, through-hole component topology. Warm Audio WA-412 4 Channel Microphone Pre-Amp with DI - Warm Audio One-Year Limited Warranty. When I first started holding regular studio sessions years ago I always desired to have more channels of high-end mic pre's. Hook-up Diagrams Inspiration behind the WA-412. The price / performance ratio of the WA-412 is almost unfathomable to the experienced studio engineer who has possibly paid much more for preamps of this style during their career. Bryce Young (founder) More f. I knew very well that if signals were not recorded well on the way in they wouldn't be salvageable later, but my budget constrained me, so many of thesources were recorded through poor-quality mic pre's. Featuring fully discrete socketed 6-pin opamps and custom wound Altran USA inputand output transformers, the WA-412 leaves nothing to be desired. X 520 discrete op-amp in every channel, socketed for convenience. 4 Channel Microphone Preamplifier Instrument DI. This style of preamp is often referred to as the sound of Rock n Roll for its BIG punchy low end and smooth open top end. The WA-412 was designed for the people (if you will) and we believe it will become a serious work-horse in many professional and homestudios. Altran USA custom wound, premium input and output transformers. The WA-412 provides 4 channels of classic American console preamps in a sleek 1 RU design. If the WA-412 was available back then I likely wouldn't have had to settle for poor, low-quality tone. I could only afford to have one or two in my studio at a time, which was never enough to record a full band or drummer.

Zapco ASP Q1 6 Channel Dash Mount Equalizer

Zapco ASP Q1 6 Channel Dash Mount Equalizer The ASP-Q 1 was designed to be an effective tool in tuning and controlling the sound of a car audio system. Crossover 2 / 3-way or 3-way Band Pass. Audiophile Quality Caps and Op-Amps. 5 Bands of Parametric Equalization. The ASP-Q 1 was not designed to be an accessory toy or a piece of jewelry for the dash. With 5 bands of parametric equalization you can put up 18 d B of correction at any points in the frequency spectrum with out being limited by fixed center points. Here is an Equalizer / Preamp worthy of the Zapco name. The ASP-Q 1 excels as a crossover as well. It is a true control preamp for your sound system. With audiophile grade internal components in the signal path and precision pots for all adjustments the sound will be clean and transparent, with rock solid bass and crystal clean highs. The aux input with its own input gain controls allow a portable source to be plugged in and level matched to the main input. You can configure a 2-way with bass and dual highs or as a 3-way crossover with a band pass. Remote Power Supply. The ASP-Q 1 is more than just an Equalizer. As a dash mount equalizer it is unmatched. The over-sized power supply gives you a 9.5 volt line driver with 14 volts available for peaks. This gives the ASP-Q 1 plenty of headroom so even on the biggest signal peaks you amp will get a clean distortion free signal.

Warm Audio TB12 500 Tone Beast Microphone Preamp W DI And 1 Year Everythingmusic Extended Warranty Free Discrete Opamp selection allows for choosing between a 1731 (vintage) and 918 (cleaner) style. Transformer selection provides both Steel and 50% Nickel Cine Mag output transformers for varying character. The different component options in the TB 12 are subtle, but when driven into saturation are noticeable and can make a big difference to the way your final mix will sound. A little change here, and another there often times became a huge deal in a finished mix, but often times is not very noticeable at first take. Transformer bypass switch allows for removal of the output transformer from the circuit. Our own reproduction of the legendary original 2520-style discrete opamp found in the classic american consoles of yesteryear. Utilizes premium grade Cine Mag USA Transformers. These op-amps will work in any preamplifier or other device which conforms to the 2520-style footprint and /-16 voltage standard. These are socketed / swappable with your choice of 2520 6 pin footprint opamps. Home-based musicians and professional studios alike will find the Tone Beast to be an extremely powerful and fully professional piece of gear that is capable of warming and shaping signals / mixes in a way that is very pleasing to the ear. Have no fear of hurting the Beast, you can push it very hard into full-on distortions if you wish, and these can sound quite nice on electric guitar, bass or anything else that likes some nice grit. When hand building mic pres I learned a bit about the subtle differences component choices can make. The TB 12", Tone Beast 500 is a high-voltage microphone preamplifier, utilzing Cine Mag USA Transformers.
