EAW Microwedge, Audix OM7, Ultimate XLR Cable Tester, Pro Audio: Joemeek TwinQ Joemeek twinQ Dual Channel EQ / Compressor / Mic Preamp

Joe Meek TwinQ Studio Channel Strip w/2 FREE Mics!

The Joemeek twinQ is everything you ever wanted in a dual studio channel - and then some!

We started with high quality Burr-Brown IC's for the preamp, added an extremely musical EQ section and an optical compressor for that signature "Meek" sound. Then we included some new and innovative features, like an "Iron" switch that switches the IC front end to a transformer - completely changing the topology of the circuit. It even has 24bit, 96k A/D converters built in.

All of this comes housed in a rugged 2u chassis with a beautifully sculpted aluminum faceplate.

With sonic quality rivalling mic pre's priced thousands of dollars more, the twinQ sets a new standard for dual channels!

Think of the twinQ as four separate pieces of equipment (twice!):

A preamplifier
A Joemeek optical compressor
An equalizer
A fader

Digital Interface

The Joemeek Digital Audio Interface provides high quality digital audio outputs plus the ability to synchronize to an external word clock. The digital audio outputs are compatible with most digital recorders, as well as Digital Audio Workstations and digital mixers. S/PDIF format is available from both the optical and the RCA phono connectors, while the transformer coupled XLR connector provides an AES3 compliant output.

The Joemeek Digital Interface has highly stable onboard master clocks for low-jitter, hi-fi results. Internal sample rates of 44.1kHz, 48kHz, 88.2kHz or 96kHz are selected by means of rear panel switches. 44.1kHz is the standard used for audio CD's, while 48kHz and 96kHz are widely used in recording studios. In general, the higher the sample rate, the better the audio fidelity, but the more disk space is required for the recording. For example, recording at 96kHz requires twice as much storage as 48kHz. Consult the manual of your recorder or DAW as to what sample rates it will accommodate.

Alternatively the twinQ may be set to the frequency of an external master word clock, generated, for example, by the studio's recorder or DAW. When connected to the BNC socket provided, a suitable external word clock will be detected automatically and will override the twinQ's internal word clock. The front panel LED labelled 'EXT CLK' illuminates when the twinQ is successfully locked to an external word clock.

To avoid distortion, care should be taken not to overdrive the input to the Digital Interface. The red LED next to the Output Gain control is labeled "PEAK FSD" which stands for "Full Scale Digital". Occasional flashes are OK but if it is on all the time, turn something down!

JM37-DP (Dual Pattern) Studio Condenser Microphone

The JM37-DP is a high quality, large diaphragm condenser microphone with Cardioid and Omni patterns. By utilizing FET devices for both preamplifier and output stages, we created a microphone that's destined to be your "go-to" mic for a variety of recording purposes.

We used classic "center-electrode" design for the capsule, which provides very smooth extended frequency response. Then we used dynamic feedback at the capacitor element, which further enhanced the audio quality by eliminating distortions that may occur at high SPL.

The large 1.035" dual diaphragms are manufactured from micro-fine Mylar with gold sputtering. The body is machined from solid brass, with connection to the outside world via a 3 Pin XLR connector. Power is supplied via Phantom Power from either your console or microphone preamplifier.

An excellent choice for male and female lead vocals, the JM37-DP also excels at recording choir, orchestral and other acoustic instruments.

- Noise Level: 19dB (A weighted)

- Frequency response: substantially flat 25Hz to 20KHz

- Sensitivity: 16mV/PA-40+/-2dB (0dB= 1V/Pa 1000Hz)

- Recommended load impedance: 200 ohm

- Max SPL: 128dB

- Power Requirement : 48V

JM27 Small Diaphragm Studio Condenser Microphone

The JM27 is a small diaphragm condenser microphone with a fixed Cardioid pattern. Building on the tradition of classic studio microphones, we combined an FET pre-amplifier with transformer-balanced output resulting in a low noise, high SPL mic - perfect for a variety of studio applications.

The capsule is manufactured in the classic "concentric electrode" design, providing smooth extended frequency response. We further enhanced the audio quality by using dynamic feedback at the capacitor element. This technique eliminates distortions, which can occur at high SPL.

The diaphragm is made from micro-fine Mylar and is gold sputtered. The microphone body is machined from brass, with audio connection via a balanced 3-pin XLR connector. Power is supplied via Phantom Power from either your console or microphone preamplifier.

You'll find the JM27 performs especially well when used for acoustic and orchestral instruments as well as in pairs for drum overheads and other stereo applications.

- Frequency response: 30Hz to 20KHz

- Sensitivity: 10mV/Pa-40+/-2dB (0dB= 1 V/Pa 1000Hz)

- Recommended load impedance: 200 ohm

- Max SPL: 130dB

- Impedance: 200 ohms
