Aurora Audio GT4-8 with GTP8 (Used)
The GT4-8 and GT4-8TRS EQ feature 30 selectable frequencies ranging from 33Hz to 15K.
The GT4-8 is designed to be used with our GTP8 eight-channel preamp. The GT4-8TRS has input and output transformers so is self-contained, though the transformers add to the costs.
Geoff’s design takes that classic British EQ sound that we all know and love and expands its usability by adding some of his own touches. Let’s look at the high-and low-end shelving. There are two gain modes to choose from. The low gain mode gives that feel of classic EQ shelving, 8dB of boost and cut. The high gain mode gives the user 18dB for grand adjustments that you may need to do. Your ribbon microphone just a little too dark? Open up the top end at shelving starting at 3.3K! Love that mid-range of your kick drum but it doesn’t have enough low end for you? Using the high gain mode to boost the lows, you will be in bass heaven in no time at all.
The mid-range is where any EQ can show its true power. The mid-range frequencies feature THREE selectable bandwidth options to choose from. The widest curve gives you the most vintage style sound, while the narrower options enable you to get more surgical. For example, the narrow curves can help you zone in on a snare drum while not highlighting the hi-hat that may be bleeding into the microphone.
The high and low pass filters are incredibly useful and musical. The LPF ranges from 3.9K to 18K and can be used for taming high frequencies or to dull something out completely. The HPF can help clean up low rumbles ranging from 22Hz to 270Hz.
When the Aurora Audio GTQ2 started to be hailed as a modern classic, the requests started coming in for an 8 channel version. In 2008, Geoff Tanner met this challenge by introducing the GTP8 to the world. 8 channels of the legendary Class A discrete sound in a convenient 2U package!
Since Geoff insisted that no corner could be cut in keeping the GTQ2 sound in an 8 channel edition, clearly the same iron would have to be used as well. Balanced transformer in and out is featured here once again. Having the same transformers that were specified by Geoff and built by the old Marinair crew had to be included in the GTP8 without question. The result is 8 channels of massive tone that is suitable for any sound you might throw at it. The Aurora Audio GTP8 has the same intuitive design as the GTQ2 as well. Dial in your level easily and accurately with discrete 10dB steps. Then fine-tune your selection with the trim pot that gives you 5 more decibels of boost or cut. This way, you can optimize your clean and pristine source to tape or DAW, but you can also use the trim to add some dirt and drive to your signal as well.
Not to be left out, also featured on the GTP8 is the awesome Aurora Audio DI. Listen to your direct signal come alive in ways you never thought possible until now! Plus, there are EIGHT of them. More is always more, right? In the past you may have avoided to go direct, but with the Aurora Audio DI and the GTP8, you will be looking for excuses to use direct injection. With this one unit, you will take your studio to the next level. Feel the power of having 8 channels of classic Class A discrete, British inspired tone within arm’s reach. For example, the GTP8 is perfectly suited for use as your drum sound. Why? Everyone knows that mixing preamps when tracking drums can be a dangerous proposition. With a mixed bag of mic pres all reacting at different times electronically and in different ways, this will affect the phase relationships of the signals and may result in a less than ideal sound. With 8 channels of the GTP8 working together in perfect harmony on your drums, you will experience more punch and clarity that only matched preamps can provide.
Think about it: All of those classic recordings that we all grew up on were tracked on consoles with matched preamps that gave the album an overall sound and signature. Give yourself the opportunity to record the way the greats always intended you to do. Make your next classic recording today with the GTP8.
