Telefunken U48 Tube Condenser Microphone Stereo Set

The Telefunken U48 Stereo Set is a high-end microphone package that includes two matched U48 tube condenser microphones and a custom-designed dual power supply. Here are some key features and specifications of the U48 Stereo Set:

Main Features:

Polar Patterns:

The U48 microphones offer both cardioid and figure-of-eight (bi-directional) polar patterns. This versatility allows for different recording applications and environmental considerations.

U48 Design:

The U48 is a meticulous recreation of the original U48 microphone, which is a variant of the iconic U47. Unlike the U47, the U48 replaces the omni polar pattern with a bi-directional or figure-of-eight pattern.

Components:

The U48 retains the same construction as the U47, including the use of the original M7 capsule, Telefunken-designed VF-14K vacuum tube, and BV8 output transformer. These components contribute to its classic and highly regarded sound.

Sound Characteristics:

The U48 is known for its strong, authoritative mid-range and extended low-frequency response. This characteristic adds gravitas and presence to vocals and acoustic instruments.

George Martin’s Choice:

According to the book “Recording The Beatles,” the U48 was favored by Sir George Martin during the recording of many Beatles albums. Its sound characteristics made it an excellent choice for capturing the Beatles’ vocals and instruments.

Bidirectional Capability:

The U48’s bidirectional (figure-of-eight) capability can be particularly useful in ambient recording environments where you want to control room ambience.

Capsule Design:

The microphone’s capsule consists of two sides—the front and rear diaphragms. When polarized in the same polarity, it produces a cardioid response, while polarizing them in opposite polarity creates a bidirectional or figure-eight pattern.

Electronic Pattern Creation:

The figure-eight pattern is not an acoustic pattern but an electronic one. It results from electronic cancellation of common information between the two diaphragms.

Power Supply:

The U48 Stereo Set includes a custom M940 power supply capable of powering both microphones simultaneously. This simplifies setup and operation.

Accessories:

The package comes complete with additional accessories, including an M840 25′ dual-shielded ACX-7 tube microphone cable, M740 elastic shock mount, FC40 locking flight case, and WB40 wooden microphone box.

Handbuilt in the USA:

The U48 microphones are handcrafted in the United States to ensure high-quality manufacturing.

Overall, the Telefunken U48 Stereo Set is a premium microphone package designed for professional recording applications, known for its classic sound and versatility with cardioid and figure-eight polar patterns. It offers the signature Telefunken quality and is suitable for capturing vocals and acoustic instruments in various recording environments.
