Being There in Stereo
In the 1930s, EMI engineer Alan Blumlein invented stereo recording by demonstrating the natural reproduction of the soundstage at one of the Abbey Road studios in London, UK. Still today, his coincident recording technique using two figure-of-8 ribbons is the benchmark for producing an authentic representation of a performance in a room. The R88 mk2 stereo microphone is a true Blumlein recording system optimized for recording instruments and ensembles in stereo. It utilizes two of AEA’s signature Big RibbonTM elements angled at 90 degrees and mounted in close proximity to each other along the vertical axis of the microphone. The natural soundstage and character of the R88’s Blumlein stereo make it a great main mic. As an alternative to the Blumlein (XY) technique, the microphone can also be used for MS stereo, providing excellent mono compatibility and full control over the width of the stereo image. An excellent orchestral and choral recording microphone, it also shines on applications such as horn sections and drum overheads, thanks to the pure sound of two undamped long ribbons and the passive circuit without the headroom limitations of active electronics. The R88 accurately records complex tones such as woodwinds, strings and cymbals.Whether it’s at Abbey Road or in your home studio, the R88 mk2 puts the listener right there with the performers in the recording room.
The Grammy-Winning Package
The list of Grammy and Academy Award winning projects recorded with the help of the R88 mk2 microphone is long and keeps growing: Turtle Island String Quartet, Los Tigres Del Norte, Juanes MTV Unplugged, Life Of Pi soundtrack to name but a few. The matched Blumlein pair of ribbons packaged in a sleek black shell designed for quick setup delivers a great sound right off the bat, making it an excellent choice for remote recording setups. As a drum overhead or room pick-up microphone, it instantly captures a punchy, “larger than life” image that is particularly well suited for rock, roots, Americana, and jazz genres. Seasoned engineers like Joe Chiccarelli, Chuck Ainlay or Vance Powell trust the AEA R88 mk2 so much that Nashville’s world-class Blackbird Studios now has an R88 available for every single room in their facility.
A Big Ribbon for a Big Sound
At the heart of the AEA R88 are two big, 2.35" by 0.185" by 2 micron pure aluminum low-tension ribbon elements just like the one used in the classic R44. Many ribbon mic manufacturers choose shorter ribbons that are easier to install, but AEA’s Large Ribbon Geometry TM design offers important advantages. Ribbon microphones operate linearly above their resonant frequency, unlike condenser or moving-coil transducers, so the resonant frequency of a good ribbon microphone design should be as low as possible. The longer the ribbon, the lower the resonant frequency will be. The ribbon has to move twice as far for every drop in octave as it vibrates within the magnetic gap, thus a longer ribbon will allow for further movement back and forth. This results in the ribbon handling louder sound sources and more sound pressure level (SPL). Most AEA ribbons are tuned to just 16.5 Hz, and because the R88 shares the same Big Ribbon™ as the rest of AEA's product line, you will achieve a sound that is smooth, natural and free from any of the uncomfortable resonances that shorter ribbons and condensers can exhibit. The result is a sound that many engineers say is astonishingly close to what their ears hear when they are actually standing in the studio.
TRP2 Stereo Ribbon Microphone Preamp
ENHANCE YOUR RIBBONS
The AEA TRP2 Ribbon Preamp provides two channels of high-output, high-impedance, and low-noise gain with a rich and natural sound that brings out the full potential of your microphones. Specifically designed for ribbon microphones, the TRP2 excels at drawing out the warmth and lush sound that ribbons are uniquely known for.
A GAIN POWERHOUSE
The TRP2 is a powerhouse that provides unparalleled high gain with low-noise. With 85db of JFET output, the TRP2 gives you enough juice to record soft sources without ever having to worry about noise. With the TRP2, you will never consider a source too quiet to record with a ribbon mic ever again. Passive ribbons with low output levels require preamps that supply a high level of output. If the preamp you use doesn’t have enough clean gain, the mic signal may seem too soft or noisy which may be apparent when recording quiet acoustic guitars or strings, especially at a distance or with long cable runs. The TRP2 eliminates this concern.
PROFESSIONAL FEATURES IN A COMPACT PACKAGE
The TRP2 is AEA’s second iteration of the high-performance TRP preamp with the addition of new features including phantom power, optional rack ears, and a switching power supply.Polarity reverse switches for ensuring proper polarity throughout the recording chain and switchable 100 Hz, 12 dB per octave low-frequency filters allow you to tame proximity problems. The TRP2 includes switchable phantom power that is capable of powering condensers and active ribbons. For engineers concerned about phantom power hurting their passive ribbons, there is phantom power kill switch, known as No Blow Mode, located internally within the unit that easily deactivates 48V from ever turning on.
HIGH IMPEDANCE MAKES A HUGE DIFFERENCE
The sound and tonality of dynamic microphones like ribbons and moving-coils are directly affected by the impedance of a preamp. The higher the impedance, the better the sound. The RPQ2 boasts an extra high input impedance of 63K Ohms. Preamps with an impedance of under 10k ohms will limit the lows, highs, and transients of your passive microphones. The RPQ2’s high impedance will reveal your microphone’s true nature– a thick low-end, open top-end, and articulate transient response that you will need to hear to believe. Both condensers and active microphones will also benefit from the RPQ2’s impedance.
A UNIVERSAL POWER SUPPLY
An external switching power supply with a grounded AC plug is used with the TRP2 so hum fields can be kept away from the high-gain electronics. The power supply allows the TRP2 to be used in any country without any modifications made to the unit.
OPTIONS TO RACK THE TRP
The TRP2 is housed in a portable and lightweight half-rack aluminum chassis. This form factor allows you to easily take it to remote gigs, other studios, and on the road. The TRP2 can be easily racked with the optional TRP2 Rack Ears. Attach the rack ears to the TRP2 and unit can be securely installed in any standard rack. Two TRP2s can be mounted side by side in a single rack space by purchasing the AEA TRP2 Rack Shelf. Screwing two TRP2s to the rack shelf, the whole assembly can be securely installed in any standard rack.
