The JFET-input operational amplifiers of the TL06_ series are designed as low-power versions of the TL08_ series amplifiers. They feature high input impedance, wide bandwidth, high slew rate, and low input offset and input bias currents. The TL06_ series feature the same terminal assignments as the TL07_ and TL08_ series. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.

The DRS-Q4M mk2 is a 4 Band Gyratory-based Eq with 11 selectable frequencies, and Mic, Line, and DI inputs. We know you will be as pleased with it’s sonic qualities as we are. The DRS-Q4M mk2 has the advantages of more than 25 years experience in audio engineering, today’s component and manufacturing technology, but still retaining ´´that sound” uniquely achievable through Class A design. Phoenix Audio is dedicated to the development of Class A discrete technology used within high build-quality equipment. The DRS-Q4M mk2 uses our well proven and loved Class A output stage (DSOP-2) coupled with our custom wound output transformer, but also has our latest breakthrough in transformerless Class A, Discrete, truly-balanced Mic Input Technology which gives a ´´valve-like” sound. It also incorporates our high input impedance DI circuitry.The Gyrator EQ circuit was designed around 40 years ago and was originally designed to emulate the characteristics of a coil or inductor EQ circuit without the issues that they can cause, the result is that our EQ circuit found in the DRSQ4M mk2 is a very powerful but musical EQ perfect for sculpting or crafting vocals, drums or instruments etc whilst still being able to be used on mix bus duties.Specifications • 1U half rack space unit: With 240V/110V mains voltage input selector switch • Class A (DSOP-2) Output specs.

The Series 80B rack unit is derived from the legendary Series 80 Consoles designed by Trident Studios in the late 1970´s. It incorporates an exact replica of the mic preamp and equaliser design that gave the original console its unique sound. These consoles have been used to record just about every major artist in the past three decades, including Elton John, Dire Straits, David Bowie, Rod Stewart and Stevie Wonder to name but a few. More recently they have been used to record artists such as Radiohead and Pavarotti.The Trident Audio Developments Series 80B rack unit therefore brings with it a historic pedigree and is offered at a price that is now affordable to the smaller studios and home recordists.Specifications:- Input Impedance:Microphone: 1.2k ohm transformer balancedLine: 15k ohm electronically balanced- Output Impedance: - Gain:Microphone: -15dB to +60dBLine: -15dB to +10dB- Noise:Microphone: Line: - Maximum Levels:Mic Input: +24dBu at all frequenciesLine Input: +24dBu at all frequencies- Distortion:Mic Input: Line Input: - Frequency Response:Mic Input: ±1dB 20Hz to 20kHzLine Input ±1dB 20Hz to 20kHz- Nominal Operating Level: +4dBu- Peak LED Threshold: +10dBu

The Portico 5012 is a dual channel mic pre featuring Neve’s custom input and output transformer designs. In addition to individually selectable phase, mute, phantom power and a fully sweepable high pass filter, the 5012 incorporates a ´´Silk” circuit which yields the rich warmth and presence of the renowned classic designs.Microphone InputThe microphone input is balanced but not floating, being a variant of an instrumentation amplifer using a ´´Transformer-Like-Amplifier” (T.L.A.) configuration with a toroidal Common Mode Rejection Low Pass Filter that excludes frequencies above 150 kHz. The T.L.A. is followed by an actual input transformer permitting a full +25 dBu input signal to be handled at unity gain without an input pad over the whole audio spectrum. This combines the advantages of both an ´´Electronically Balanced” and true transformer input. When the Phantom voltage is switched off, this input serves as a very high quality line input with an impedance of 10,000 ohms.Low Noise, Low Distortion OperationMuch care was given in designing the 5012 to produce as little noise and non-harmonic distortion as possible. Carefully implemented signal paths and Class A operation are a large part of the 5012′s sweet, whisper quiet performance.Why Transformers?A complete discussion on transformers is out of place at this point but a technical discussion will be posted at a later date. Here it is helpful to review some of the essentials where it will be seen that a design needs to be viewed as a whole, not simply from the point of view of a single component.The fine subtleties of circuit design relating to sonic performance are gradually becoming more clearly understood. For example, research has shown conclusively that frequencies above 20 kHz affect the way in which humans perceive sound quality. But, long before scientific evidence emerged a substantial body of musicians and engineers knew that equipment with apparently the same technical measurements could sound very different.Incredibly small amounts of musically dissonant odd harmonics have a disastrous effect on the sound quality. Extraneous noise or interference that finds its way into a signal path seriously impairs performance of the whole chain.Many control rooms make use of outboard gear that is not well protected from external signals. Poor grounding of such equipment can be a serious problem. ´´Electronically balanced” circuits much used in modern equipment, can give very good measurements on the test bench but they do not provide adequate rejection of the stray fields found in every working environment.Input and output circuits must be freed from ground dependence so that only the ´´wanted” signal enters and leaves the processing path. Transformers are the ideal solution. The sweet and silky sound of my classic old favorite consoles was achieved with big transistors and large high quality transformers. Rupert Neve Designs Portico modules achieve similar quality today without the bulk or the cost.In order that modules can work together as would be expected (i.e. in a proprietary console configuration) without producing hum, R.F. interference, or other interactions, the connecting interfaces, grounding, levels and impedances must receive careful attention. Each Portico module is a complete integral signal processor that delivers its specified performance independently. This is one of the reasons we use transformers.
