PEARL PML CT40/DT40April 2004—The CT40 uses Pearl's revolutionary, dual-membrane, rectangular capsule with a fixed cardioid polar pattern and is powered

November 2007—Pearl (dist. by Independent Audio, has released a new rectangular capsule mic, this time with dual, back-to-back membranes and outputs. The $3,196 ELM-A feeds the twin outputs via a 5-pin XLR connector with both outputs delivering independent cardioid signals, one from each membrane for back-to-back output or 180-degree stereo. The rectangular capsule has more than twice the surface area of large-diameter round capsules, which provides excellent signal-to-noise ratio while avoiding high levels of in-band resonance. In addition, the mic’s small width lets users tune out unwanted reflections due to the narrow side-to-side pickup pattern.

February 2007—Pearl’s TL4 ($2,267) and TL44 ($2,513) both combine the company’s classic rectangular, dual-membrane capsules mounted back-to-back in a compact black-chrome body. Each offers cardioid, figure-8, omni and 180-degree coincident stereo polar patterns. Both models have 5-pin XLR outputs, weigh 9.1 ounces and use quiet, transformerless preamplifier circuits. Response of both mics is 20 to 20k Hz, with 126dB SPL handling. The TL4’s sensitivity is rated at 120 mV/Pa; the TL44’s is 16 mV/Pa.

February 2007—Pearl’s DS60 ($6,241) model supports X/Y, M-S and Blumlein techniques. Its brass body is finished in black chromium and gold-plated mesh, and it has two rectangular dual-membrane capsules mounted one above the other at 90 degrees apart. Each capsule offers a selection of cardioid, figure-8 and omnidirectional patterns. The DS60’s response is 18 to 25k Hz. Its preamplifier has four output channels — one for each cardioid membrane — that are connected via a 9-pin Lemo plug and a four-way splitter terminating in 3-pin XLRs. Its sensitivity is rated at 16 mV/Pa with self-noise at 15 dBA.

January 2006—Pearl, the company from Sweden that specializes in rectangular capsule microphones, has released the Pearl 0M 16 ($550), a traditional circular capsule mic distributed by Independent Audio. The medium-sized, front-address omni condenser mic has a transformerless design, and is mostly flat but with a 3dB boost from 5 to 12 kHz, targeting it largely for instrument and ensemble recording.

October 2005—The Pearl OM 16 is a small omnidirectional condenser mic. The transformerless circuit achieves a very flat frequency response but with a boost from 5 to 12 kHz of 2.5 to 3 dB (at 8 kHz). The OM 16 sounds very natural and uncolored, which makes it an excellent choice for capturing musical instruments and vocal performances. Price: $575.

July 2005—A cardioid condenser microphone, the TLC 90 ($675) from Pearl features a uniquely shaped capsule housing that prevents performers from holding their hand over the back openings of the capsule and compromising the TLC 90’s directionality, thus maintaining the mic’s ability to reject feedback. A removable grille facilitates easy cleaning, and an internal shock-mount reduces handling noise. A red LED on the mic body indicates when phantom power is present (30 to 48V DC required). Frequency response is 30 to 20k Hz with a max. SPL of 144 dB (0.5% THD); impedance is 500 ohms.

May 2004—Pearl takes rectangular mic capsules to new extremes
with the figure-8 ELM-B ($2,425) and cardioid ELM-C ($2,000). The
black-chrome-finished mics feature a 7:1 length/width capsule ratio,
with more than twice the surface area of large-diameter round capsules,
and offer a 12dBA self-noise and none of the in-band resonance found in
more traditional designs. TO READ THE REVIEW ON THE ELM-C, CLICK HERE.

April 2004—The CT40 uses Pearl’s revolutionary, dual-membrane,
rectangular capsule with a fixed cardioid polar pattern and is powered
by a Nuvistor vacuum tube. The PML DT40 offers a choice of five
different polar patterns and is also tube-powered. The combination of
the rectangular capsule with its excellent sonic neutrality and the
warmth of the Nuvistor tube give these microphones a sensational sound.
PMLCT40, $3,750; PMLDT40, $3,900.

November 2003—At AES NYC, PLM (dist. by Independent Audio, unveiled the DT40
(five-pattern) and CT40 tube mics, based on Pearl’s classic,
large-diaphragm, rectangular condenser capsule, paired with Nuvistor

July 2003—Sweden’s Pearl Lab introduces the CO 22, its newest
studio condenser microphone. This large-diaphragm, phantom-poweredomni
boasts low self-noise and flat response both on- and off-axis.
