Atlanta’s Audio Engineering Society chapter had an awesome meeting at Summer Street Productions with John Jennings from Royer microphones.

I’ve always loved Royer for designing gear made to sound right using super solid design skills. John gave a great presentation talking about and showing us with audio samples the true benefits of their well-designed mics.

John brought various things to show us. This photo shows….can you believe: sample number one of the R-121. Very first one. That’s crazy…..

Our YouTube channel has a new video about our OA241 Discrete Op Amp module. It is a great sounding amp that fits the industry standard API 2520 footprint. Drop it in as a replacement for a blown module or as an upgrade to the sound of your gear. The OA241 has a JFET input and BJT outputs biased to allow it to sound great as you push it harder. Contact us or one of our dealers for more info.

Periodically, Ingram Engineering posts tips and application information for its recording studio products. This post relates to using the EQ52 to implement the high frequency characteristics of an NAB tape equalization curve in a setup that emulates tape high frequency magnetic saturation.

In this case, a pair of Ingram Engineering EQ52s is used in conjunction with a companion piece of gear that adds a pleasing amount of saturation when driven hard. Signal is first be passed through one EQ52, then to the saturating stage. Signal level into the saturating stage, or the gain of the saturating stage is adjusted so that the desired amount of distortion is achieved.

To complete the saturation effect, the saturated signal is passed through a second EQ52 that has reverse frequency characteristics as the first EQ52 in order that the overall response is flat, or even adjusted so that high frequencies are slightly attenuated. This mimics the slight high frequency reduction of saturated tape. For this example, only the high frequency part of the NAB curve is used, with its 3183 Hz frequency break point. Note that the amount of boost/cut is different between the two EQ52 See-Saw filters in order that slight high frequency reduction is achieved.

The NAB curve example is given, but the same idea could be applied for an IEC type or custom EQ curve for this and many other applications.

Why are we posting a picture of the API 312? Look closely and you’ll see that the 2520 op amp has been replaced with the Ingram Engineering OA241 op amp. This discrete op amp module provides a serious upgrade to the API 312 sound. For that matter, the OA241 is a perfect substitute for any discrete op amp that fits the API op amp footprint, whether used with a socket or is soldered to a PCB.

The OA241 has a sweet sound that adds a subtle amount of JFET goodness and has a more gentle transition into overload than most audio amplifiers. And the OA241 has a super low noise floor that rivals any design, whether BJT or FET.

Whether it is the API series that needs improvements in sound quality and reliability, or any other mic pre amp or processing gear that uses the standard discrete op amp socket, the OA241 is optimized to provide just the right amount of color for today’s situations that are dominated by sterile recording chains.

Contact Ingram Engineering for pricing. Modules are available with long or short pins.

Periodically, Ingram Engineering posts tips and application information for its recording studio products. In a previous post, we showed how the EQ52 500-Series Equalizer module could soften the attack of a guitar track played with a pick. This post relates to using the EQ52 to do the opposite: make a guitar track recorded with finger playing sound more aggressive, as if a pick was used.

For this example, we’ll assume that the take was perfect, and you don’t want to try to retrack it. However, the soft guitar finger sound isn’t sitting perfectly in the mix, and it should be brought out more.

The EQ52 filters can be very effective at accentuating the higher frequency transients similar to what you get when you use a pick. The settings shown in the photo were dialed in for a track that used a Fender Strat with medium gauge strings and a Fender Twin amp. Try it for yourself to see how effective it is.
