That being said, some microphone preamps double as instrument preamps and even line amps. Microphones generally connect via balanced 3-pin XLR cables, so the overwhelming majority of microphone preamplifier inputs will be female 3-pin XLR. The inputs specification refers to, well, the inputs of the mic pre. Related article: Do Microphone Preamplifiers Improve Sound/Audio Quality? UK Made – Blore Edwards EQ Dual-Concentric Switch Potentiometers.Connections: Transformer balanced I/O (custom wound).In addition to tubes and transformers, this specification can tell us how the circuits are constructed and other specific elements that are important to the functionality of the amp. The quality of the transformer will also directly affect the quality of the sound. Output transformers are also important for tube preamps and some solid-state mic preamps as well. The quality of the tube(s) is a major factor in the quality of the mic pre, and it's important to note the tube used in case of replacement. The circuit/components specification will tell us about any special components used in the microphone preamp design.įor example, the vacuum tubes used in tube preamps are of great importance. Same hand-wired modular design that BAE is known for.This “spec” will include several other specifications that the manufacturer believes should be known. The features section of a mic preamp specs sheets lists out important bullet points about the microphone preamplifier. Description: Dual Channel, Class A, ’73-Style British Microphone Preamp With EQ.Chandler REDD.47Ĭhandler Limited's REDD.47 Mic Amplifier is a recreation of the original valve line amplifiers used in Abbey Road Studios' heralded and rare EMI REDD.51 recording consoles circa 1959-1968. Examples Cloud Microphones CL-ZĬompact, single-input solution for common audio problems in the field and the studio involving low-output passive microphones, including ribbons. The description includes information the manufacturer thought important to include about the microphone preamplifier (applications, circuits, amplifier class, EQ, etc.). Rather, it's a paragraph (or several) written by the manufacturer (typically by the marketing team rather than the engineering team) to describe the particular unit. This “specification” is typically not in the technical specifications section of the mic preamp specs sheet. Power Supply & Requirements/Consumption.Gain Control (Voltage gain – Fine gain – Total gain).The included links will bring you to the bottom of this article, where each of the preamps is described in more detail, with all their specifications laid out as a reference.Īlternatively, you can skip to the section Preamplifier Examples For This Article by clicking the link.

To provide real-world examples of each specification, I've collected a series of datasheets/product pages from specific mic preamp manufacturers of various headphone types. I will also add real-world examples of microphone preamplifiers that have the specifications mentioned.

Each spec will be described briefly with links to more in-depth articles when applicable.

I will list all the potential specifications you may find on mic preamp datasheets, manuals and selling pages. This is especially true if the preamp unit offers additional functionality (PADs EQ and filters phantom power, etc.) However, the actual electronics of the amplifier vary in complexity and can be defined by all sorts of specifications. The role of a microphone preamplifier is fairly simple to understand: it boosts the mic level signal of the microphone to line level, allowing the mic signal to be effectively processed, recorded, and played back. Related article: What Is A Microphone Preamplifier & Why Does A Mic Need One? Note that some microphone preamplifiers are subject to different specs than others based on their functionality. In this article, we'll describe each of these mic preamp specifications and what they mean to the overall functionality of the preamp in question. What are microphone preamplifier specifications? Mic preamp specifications, shown on specifications/datasheets and product pages, are pieces of information that tell us the electrical and physical characteristics of the preamplifier and the features available for use within the mic preamp. Microphone preamps come in various shapes and sizes and are defined by a list of specifications. If you're familiar with microphones, you'll know that they require preamplifiers to boost their relatively low-strength output signals to usable levels.
