This is especially true in low-level input applications to achieve extremely low noise floor, minimum distortion, wide bandwidth and linear phase response. This approach can be obtained a warm sound, crystal clear and fast response, getting a step closer to the human ear characteristics.\u003c\/p\u003e\u003cp\u003eEach MPX-4Aii unit uses a Class A, auto-bias bridge configuration, hybrid input stage preamplifier based on hand-selected transistors for the lowest of noise, and the lowest possible base-spreading resistance and collaterally matched for perfect balance, and biased at the precise levels that make them maximally insensitive to thermal drift. As a result, no offset crowding occurs, and the dynamic range remains wide open. Because of the wide gain-bandwidth parameters of these specially-selected transistors, and the super-low impedance characteristics, and the vanishing circuit reactance, the impulse response is optimum, and phase-delay distortion undetectable. Gain adjustments are made with balanced differential-mode cancellation, preserving the excellent DC offset characteristics, without altering the loop feedback characteristics from their optimal configuration.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eControls:\u003c\/b\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA premium quality gain control is followed by three rugged but nimble pushbutton controls for each of the MUTE, PHASE, and 48V (Phantom Power) functions.\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eThe MUTE control allows the individual preamplifier section to be silently switched out of service.\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eThe PHASE control allows the inversion of signal polarity.\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eThe 48V control switches on phantom power, necessary when using condenser microphones.\u003c\/li\u003e\n\u003cbr\u003e\u003cli\u003eAdditionally, each preamplifier section has a Peak indicator, set at -8dB before clipping the signal output.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mytek Digital","offers":[{"title":"Default Title","offer_id":44449636941927,"sku":"21253","price":675.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_21253_1_733e29ac-9eb0-455e-9219-136562e5be44.jpg?v=1787089784","url":"https:\/\/vintageking.mom\/products\/sytek-mpx-4aii-mic-pre-used","provider":"Vintage King","version":"1.0","type":"link"}
