A Designs Jm3001 Solid State Mic Pre With Eq $2375 The JM-3001 from A-Designs Audio is equally ideal for both studio recording and live sound use. Hand-built in the US, the new A-Designs JM30001 features three inputs: microphone, instrument and EQ/insert, which may be used together or independently. The product is also equipped with a highly musical three-band parametric EQ, high/low filters, and two independent transformer-balanced outputs (microphone and EQ).The heart of the JM-3001 is its C12X discrete-transistor operational amplifier designed by Carl Johnson. Operating on 30VDC rails, the C12X is a high-gain, fast-slew, stable audio block with virtually no DC offset over the audio spectrum, and is capable of driving a 50 ohm load at 50Hz with very little current draw. It is used in the microphone preamp, instrument input amp, and main output/EQ output stages of the product.According to A Designs' Peter Montessi, The JM-3001s preamp is an original design with depth and detail for miles, while the EQ is a full parametric with its own transformer, so you can use it with or without the pre. The freq settings are highly reminiscent of classic console filters and musically complement any source you run through them. The instrument input is totally separate from the pre and EQ and sounds amazing on its own as well." The JM-3001s microphone preamplifier is a single-stage, transformer-coupled and balanced I/O design benefitting from the C12X for ultra-transparent audio. This section feeds the EQ and preamp output mult simultaneously and includes phase reverse, a -20dB pad, +48V phantom power with LED indicator and a plastic conductive gain control pot.The instrument input preamplifier is a single-stage, single-ended, high impedance input designed primarily with guitar and bass pickups in mind. Similarly utilizing a C12X discrete op amp, this section is separate from the mic pre and includes a 1/4-inch phone jack and gain pot on the front panel. Like the mic preamp, this section also feeds the EQ and preamp output mult simultaneously.The equalizer input/insert return is a direct-coupled, balanced input that is post the mic pre and the instrument input. Inserting a TRS 1/4" phone jack into this connection allows for direct input to the equalizer, bypassing both the mic pre and instrument input.The JM-3001s three-band parametric equalizer is a unique design featuring 33 frequencies with three bands of overlapping ranges covering from 50Hz to 15KHz. Both the frequency selection and the 12 dB equalization controls are step-type switches for precise and repeatable settings. Each band has a Q switch with three fixed positions: sharp (S), wide (W) and narrow (N). The low and high bands are normally of a peak/dip type, but flipping the shelf switch to the up position on those bands changes the characteristic to shelf type. The shelving switch disables the Q feature on high and low bands only.When in the up position, the high/low filters insert the fixed 12dB/octave high- and low-cut filters. These filters work

Drawmer 1960 Mic Pre/Tube Compressor $2250 Combining eight active tube stages and the low noise and reliability of solid state electronics, the Drawmer 1960 provides the ultimate direct interface between the sound source and the recording medium. The Drawmer 1960 is a two channel unit with each channel comprised of a completely natural sounding "soft knee" vacuum tube compressor and an extremely low noise microphone pre-amplifier with switchable 48 volt phantom power. A further auxiliary instrument pre-amp with EQ is also provided. This powerful combination of the classic valve circuit, offering unsurpassed tonality, and the low noise balanced microphone input with up to 60dB of gain has allowed engineers throughout the world to exploit the full potential of high performance condenser microphones. An example of this would be the direct to digital stereo recording of live classical music without the necessity of a mixing console. The Compressor: Because the compressor is a soft knee type, it requires few controls. Strictly speaking, a soft knee design does not have a rigidly defined threshold but the title 'Threshold' has been retained for the "amount of compression" control for the sake of familiarity. The Threshold range is continuously variable between infinity and -24dB, the theory being that signals below the threshold are essentially unprocessed and the signals exceeding this threshold are subjected to increasing amounts of gain reduction dependent on by how much they exceed the threshold._The attack and release times are switchable rather than being continuously variable and this method of operation falls into line with that of its all valve predecessors. Attack simply offers a-choice of slow, medium and fast whilst release has six settings. Positions one to four have fixed release times whilst positions five and six are two different programme dependent release time modes making the unit ideally suited to programme material with complex dynamics such as complete stereo mixes and vocals. Interestingly, the attack times are further modified by the choice of release setting so the range of choices are wider than it might first appear. Because compression is a form of controlled gain reduction, a stage of make-up amplification follows the compressor section giving a range of +20dB. The VU meters may be switched to monitor either the amount of gain reduction taking place or the output signal level and the two channels may be used either independently or as a stereo pair, depending on the setting of the stereo link switch. The side chain access points may be used to patch in equalisers to enable the compressor to act as a de-esser. As with other Drawmer products, the by-pass switch offers a choice of Normal. By-pass and Side Chain Listen modes so that if you have patched in any additional side chain processing, you can easily monitor what effect it is having. In addition to the balanced microphone and line inputs on the rear of the unit an auxiliary input on the front panel gives dir

Used Focusrite Isa One Classic Single Channel Mic Pre With Di $454.99 The ISA One microphone preamplifier delivers Focusrite's prestigious ISA transformer-based preamp in a rugged and portable chassis, at a groundbreaking price. ISA One features the classic vintage microphone preamplifier topology from the original ISA 110 module, including the Lundahl L1538 transformer and bespoke zobel network. (The original 110 pre amp formed the cornerstone of each channel of Focusrite's legendary Forte console.)The pre-amp is complemented by a line input (XLR and TRS Jack) and an independent DI channel, complete with dedicated gain control, active or passive impedance switch, a TRS Jack output for routing to an amp and an independent XLR output on the rear. This flexible independent DI makes the ISA One ideal both for engineers wishing to blend a DI'd guitar signal with a mic'd guitar cabinet, and for demanding performers who require a single classic solution for both guitar and vocals.A variable impedance circuit has been added, allowing the user to switch between four carefully selected input impedance settings. In addition to the original ISA 110 impedance, three further impedance settings allow perfect matching, or creative mismatching of the pre amp with any microphone. ISA One also features an insert point, should the need arise to place extra processing between the preamp or DI, and the optional converter. Phantom power, phase reverse and a 75Hz, 18dB/octave high-pass filter are also available from the angled front fascia.Independent input metering for both channels is provided in the form of a moving-coil VU meter with variable calibration to suit analog and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert. The meter calibrations utilize all the same reference points as Digidesign's Pro Tools HD system, allowing effortless line-up.ISA One's headphone output features a dedicated volume control, which delivers an external stereo cue mix, (a simple click track, or a stereo mix feed from an interface or a live console,) fed to the headphones via two TRS jack inputs on the rear of the unit.An optional state-of-the-art stereo A/D converter is also available (the same card as used with the ISA430 Mk II), embodying cutting-edge conversion technology seated within Focusrite's custom analogue circuitry. This optional card can be retrofitted at any time and provides two channels of 24 bit/192kHz A-D conversion with a dynamic range of 119dB.The ISA microphone preamplifier was first introduced back in 1985. This transformer-based preamplifier formed the first half of the ISA 110 mic-pre and EQ module on Focusrite's critically acclaimed Forte console.

Also the soundboard alters the beat, pitch or it may alter the sound signals. The soundboard gives small alteration in every new step. The soundboard consist of different types of applications is present. The soundboard is used to merge signals from two different microphones so this is the example for the soundboard. As a result the merged sound of soundboard is heard only by single set of speakers.

The above example is helpful to prepare the two actions is heard during the single set of speakers.

The audio mixture frequently has the subsequent mechanism for the input section:

1. Input jacks/Microphone pre-amplifiers: The section during the sound enters the mixer .Input jacks/microphone pre-amplifiers used to block the microphones and pre-amps.
2. Basic input controls: The basic input controls are used to control the pitch, bass, treble and so on of the input signals. Every input slot approaches with some guide controls about it. The differences in the sound can be used by the skilled professional. By the help of settings to rectify the small differences in the sound before the sound gets recorded.

For example in ordinary two speakers setup, routing section is to decide whether in which portion the music would be heard during the left speaker and it is used to determine which portion must be heard during the right speaker. For this purpose the routing section is used.

The potentiometer that is controlled by the sliding volume control to regulate the amplitude at the end of the mixture of channels. The input and subgroup faders controls only single channel of audio or it will make some small adjustments. That is possible over in this Input and subgroup faders.
