EMI TG12413 Zener Limiter

The EMI TG12413 Zener Limiter is the ultimate TG Limiter issued in celebration of the 75th birthday of Abbey Road Studios. The Zener Limiter was conceived by Chandler Limited designer Wade Goeke and is based on the vintage EMI circuits used to record The Beatles and Pink Floyd. This newest EMI Limiter continues the tradition of EMI Limiters started in 1956 with the RS114 tube limiter, and continued with the RS168 Zener Limiter in 1966, part of the TG12345 console channel in 1968 and TG12413 in 1974. The newest version borrows from the RS168 Zener Limiter and TG12345 console strip to make a new fully featured and flexible unit for modern use. It is interesting to note that the TG Limiter was originally designed to replace both the Fairchild 660 (Limit Mode) and the Altec 436/RS124 (Comp 1 Mode).

Manley Massive Passive

The Manley Massive Passive Mastering Version equalizer features a simple, passive design – not a standard parametric design – for more natural, organic shaping. It also offers mechanically detented knobs for both Gain and Bandwidth controls, so you can easily repeat your settings. On the Massive Passive Mastering Version, both the Gain and Bandwidth controls intentionally interact, and the bands interact, as well – this creates an incredible-sounding result without sounding “colored” or “processed.” Also, both higher and lower than the normal version, the Manley Massive Passive Mastering Version’s filters are tailored to mastering purposes.

Waves L2 Ultramaximizer

Waves L2 Ultramaximizer. Using the L2, most material can be made to sound significantly louder without the subjective nature of the music being changed in any apparent way, and when you’re mastering for CD production, that’s what’s usually needed. How many times have you made a CD of your own mixes only to find it sounds rather quiet next to a commercial album? That’s because the professionals use elaborate limiters like the L2 Ultramaximizer.

Avalon VT-747SP

The Avalon VT-747SP combines a creative STEREO tube-discrete Class A spectral-opto-compressor with a musical six band program equalizer, L-R output level and gain reduction metering and internal regulated power supplies in a 2U space. Ideal for high performance DAW input signal conditioning, stereo buss compression-EQ, stereo keyboards and analog mastering applications.

TC Finalizer 96K

TC Finalizer 96K – Used at out studio as an DA/AD converter upsampled to 96K. New true 24bit resolution A/D and D/A converters. Sample Rate Converter translates AES/EBU, S/PDIF and Tos input to the Finalizer’s internal or external rate. The Finalizer 96K is performs full Up- and Down Sampling, and the Sample Rate Conversion rate is e.g. 32, 44.1, 48, 88.2 and 96kHz.

Aphex 204

Aphex 204 – Legendary Professional Two Channel Audio Enchancement – 35 Years and Counting. The Optical Big Bottom adds a deep, powerful low-frequency punch, without the unwanted level boost that comes from adding traditional EQ. Deeper, more resonant bass response with tighter articulation helps to extend low frequency power and spectrum without the build-up or driver-damaging tendencies of bass EQ. For entire mixes, the Aural Exciter brings out detail, clarity and imaging that elevates your sound without adding level. For vocals and spoken dialog, it can dramatically increase intelligibility. On mixes, it adds power, presence and sparkle. The Aural Exciter is the ideal solution for breathing life into MP3s and other compressed audio files.

Mackie HR824

Mackie HR824 – The stereo sound field is wide, deep, and incredibly detailed. High frequencies and midrange are clean and articulated. Low frequencies are no more or less than what you recorded – you can actually hear the distinct tonal qualities (and harmonic quantities) of a particular bass instrument – instead of just a “generic” bass note. Most important, the sweet spot is a broad, 3-dimensional area that gives you room to move up, down, and across the console. In short, instead of having its own distinctive “sound,” the HR824 sounds like the outputs of your mixer.

Mackie HRS120

Mackie HRS120 – Designed for professional recording studios and film/video surround post-production facilities that require extremely accurate bass extension to 19Hz and below, the HRS120 is also an excellent choice for home theater surround sound installations.

Tascam – CD-RW900SL

Tascam – CD-RW900SL – One of the most popular CD recorders on the market, the CD-RW900SL, features a robust slot-loading transport, 24 bit A/D & D/A converters, MP3 playback, key control, sample rate conversion, and selectable CD disc reading speed.
