This podcast (Gold Microphone) is a spinoff from Drew Cook's project to play and document every Infocom game. You can find that content (still in process) at Gold Machine. Drew Cook and Callie Smith come together here to have less formal conversations about the joy of playing these classic games.
In over 11,000 sq ft, Arches London Bridge provides cavernous gallery space to showcase Direct From Graceland: Elvis. The exhibition will feature artifacts owned by Elvis Presley, direct from the icon’s Graceland Mansion in Memphis, Tennessee - including his military uniforms, his American Football uniform, his TCB Super Trike Motorcycle and Ferrari Dino GT4, and a fantastic array of his famous jumpsuits – plus personal items like Lisa Marie’s baby clothes, Elvis’ first job application and the crayon box he took to school. A large and suitably retro knob sets the mic gain, up to a generous maximum of 72dB, though the bulk of the gain comes from the solid‑state (class A Analogue Devices SS2017 chip) front end. Laser‑trimmed input resistors are used to achieve a high degree of common‑mode rejection, which means less interference when using long balanced mic lines. The valve stage comes next, and contributes just 6dB to the overall gain along with whatever magic it is that valves bestow. Using a hybrid approach like this is not a new idea by any means, but SPL have been fastidious in their choice of components and circuit board layout to enable them to achieve a dynamic range in excess of 110dB along with very low distortion. In effect, they've achieved the paper spec of a well‑designed, all‑solid‑state preamp while still including a valve stage. A star grounding system is used to minimise hum, while each channel has a separately regulated phantom power supply. Drew and Callie don't monetize any content from the Gold Machine project. The best way to reward our efforts is by reaching out. Start a discussion, suggest a game, or leave a nice review someplace. We started these IF projects to meet people and have some rewarding IF conversations.
What sets the U 87 Ai apart is its unique combination of linearity and character. Although its on-axis frequency response is remarkably flat, it does exert certain charisma. It just sounds right! This makes the U 87 Ai both versatile and instantly recognizable. Classic Neumann Engineering Direct from Graceland: Elvis is a major new retrospective exhibit that will open October 2023 at Arches London Bridge . The exhibit will feature over 400 artifacts that have never been seen in the UK. Graceland Archives has assembled a powerful narrative that will explore Elvis’ meteoric career, larger-than-life persona, influential sense of style, life at Graceland, plus lesser-known aspects of his early years, hobbies and personal life. A small moving‑coil VU meter monitors the signal level, and setting a nominal 0VU peak level delivers the optimum conditions for valve drive and minimum noise. Other than the gain controls, there are just five other buttons per channel, each with its own indicator LED. First is the 48V phantom power, followed by Phase Reverse, a 30dB pad, 12dB/octave 50Hz high‑pass filter, and of course the enigmatic FLAIR button. When the Gold Mike is switched on, a warm‑up circuit mutes the audio for a few seconds until the valves' anode and heater voltages have settled, then the unit springs to life. Nevertheless, as most valve circuits take a few minutes to warm up completely, it may be best to switch on the Gold Mike a short while before you need to do any serious recording. After that, using it is absolutely straightforward — all you need do is adjust the gain to get a nominal 0VU on signal peaks, which also optimises the signal level fed into the valve stage.
The exhibition also moves beyond the familiar story of his musical and acting career to present his more private side - his devotion to his parents, his love of books, motorcycles, horses, karate, and his iconic Graceland Mansion. It includes garments and jewelry worn by Elvis throughout his life, personal items from Graceland, vintage Elvis-branded merchandise, costumes, scripts from Hollywood movies and much more. the FLAIR button is interesting. According to the manual, there's something like 2.5dB of boost centred at 6kHz, but the subjective effect seems much more subtle. The sound remains perfectly smooth but articulation improves and details stand out more. I can't help but get the impression that most of us employ a dual standard when it comes to deciding what we're prepared to pay for studio equipment: if something makes an interesting noise, we'll dig deep to be able to afford it, but at the same time we seem to resent paying a penny more than we have to for gear like microphones, mic preamps, patchbays, cabling or even computers. Even so, just about anyone who's had any experience at all in recording will concede that good mics and good mic preamps can make a significant qualitative difference to the way a recording sounds — the trouble is that the esoteric models tend to come with esoteric prices.

Aaron's current project, 50 Years of Text Games, is a history of interactive text as told in essays, images, and infographics. See below for more information, including Aaron's sample book chapter about A Mind Forever Voyaging. We're looking forward to seeing the final product! The addition of the FLAIR enhancement is tasteful and effective, and though it isn't adjustable, the amount of gloss added is subtle enough and musical enough that further adjustment would probably be quite unnecessary. SPL first came to fame with their Vitalizer, a sort of enhancer‑cum‑equalizer based on psychoacoustic principles. Since then, little psychoacoustic twists have popped up in many of their designs, and the Gold Mike is no exception. This time they've developed something called FLAIR that can be switched in to gently enhance the presence of vocals and other sounds. Unlike so‑called 'Air' EQ that relies entirely on high‑frequency EQ boost, FLAIR combines a broad‑band boost centred at 6kHz with phase‑shifting effects to accentuate upper harmonics without making the sound rough or aggressive. The circuit employs an inductor/capacitor filter and mixes directly in with the valve's source signal via a front panel switch. There's no user adjustment — you either use it or you don't. I read the manual twice to try to find out what FLAIR actually stands for, but if it's in there, I couldn't find it! Layout
For fans who cannot make the journey to Elvis’ home in Memphis, Graceland is coming to you in London! Technically speaking, the U 87 Ai is a traditional design whose timeless formula has remained unchanged for decades. The U 87 Ai uses the same dual diaphragm condenser capsule design as its predecessor, the no less legendary U 67 of the early 1960s. Its head amplifier, too, is based on the same design principles as its tube driven predecessor, but the U 87 Ai realizes them by means of a unique FET circuit with a minimal signal path and a transformer balanced output, ensuring maximum signal integrity and high common mode rejection. The pad and LF rolloff switches also do exactly as you'd expect, but the FLAIR button is interesting. According to the manual, there's something like 2.5dB of boost centred at 6kHz, but the subjective effect seems much more subtle. The sound remains perfectly smooth but articulation improves and details stand out more. It's as though the sound gets closer and becomes better focused but without any blatant signs of enhancement. Furthermore, FLAIR doesn't seem to have a significantly adverse effect on sibilance. Conclusions Among the items from Graceland that will be displayed is Elvis' red MG automobile as featured in his classic film "Blue Hawaii," a gold-plated rotary dial telephone from Elvis' upstairs bedroom, the keys to Graceland and his gold microphone used on stage in Las Vegas, 1969. Some of the most recognizable items traveling from Memphis to London are the Gold Lamé Suit worn by Elvis in the 1950s, plus one of the two jumpsuits he used for his 1973 "Aloha from Hawaii" television special and the cape he famously tossed into the audience at the end of the show.
Normally, the phase switch is only useful when recording with two or more microphones when there may be phase differences to compensate for, though there is at least one situation where it can be useful with a single mic. I don't know if you've noticed this before, but switching the phase of a vocal mic when you're monitoring your own performance via headphones causes a very significant timbral change. This is due to the interaction of the sound of your voice inside your head and the sound from the headphones. Often you'll find one position better for monitoring than the other — you can try this on any mixer or mic preamp that has a phase switch. Callie Smith and Drew Cook welcome guest Aaron A. Reed to discuss his 50 Years of Text Games project as well as 1985's A Mind Forever Voyaging. Aaron's experiences as both reader and author lead us to some great exchanges and insights into Steve Meretzky's classic game about art, political witness, and as-yet unexplored possibilities in computer games.
Viewed simplistically, the Gold Mike comprises a pair of independent mic preamps sharing the same 2U case. Convex mesh grilles on the front panel show two selected ECC 83 (dual‑triode) valves glowing away inside the unit, but as with other SPL tube products, this one uses hybrid circuitry in an endeavour to combine the best attributes of both valve and solid‑state technology. The U 87 Ai is the epitome of a large diaphragm condenser microphone. Its tapered body and iconic headgrille design have become part of the collective consciousness: This is what a studio microphone looks like. The same is true of its sound: The U 87 Ai represents studio quality; it has become the gold standard by which other microphones are measured.Overall, the sound of this preamp is exceptionally clean and open without the hint of muddiness that some valve processors introduce. It's difficult to evaluate the valve's contribution to the proceedings, but it does seem to help the various components of the sound knit together more naturally. A lot of care has gone into the technical design of the Gold Mike, not only in the audio circuitry, but also in circuit board layout and in the crucial area of the power supply. The result is a classy sound that's both detailed and very smooth. SPL used to have a reputation for being both esoteric and expensive, but as the company has grown, they've looked into ways of delivering high‑quality audio processors at more affordable prices. The SPL Gold Mike preamp reviewed here is designed to compete with some of the best mic preamps around, yet it has a distinctly mid‑market price tag, well within the reach of any serious project studio owner.
