    Knock-Boxx MPHC1 High Current Stereo Pre-Amp with API Transformers

    The Knock-Boxx MPHC1 is a high-current Pre-Amp designed specifically for boosting the signal from modern drum machines and DAW’s. It provides analog warmth and flavor to sterile digital signals, making them sound much more pleasing to the ear. This is a fully analog device, designed for beat-makers, music producers, studio engineers, and mastering engineers. This analog stereo pre-amp is a game changer. For each channel, the unit employs a Ratio and LFB switch. They can be used together or separately to enlarge the size, punch and weight of the low end. The unit comes stock with TI NE5532P Op-Amps in IC sockets. The Op-Amps can be swapped with different IC’s to augment the sonic tone of the unit.

    Swiss Army “5 in 1” Audio Device: High Current Pre-Amp with 600 ohm API Audio Transformer Output, High Current Isolation-Amp to Reduce Noise & Hum, High Current Distribution-Amp for Long Cable Runs, High Current / Quality Headphone-Amp for Mixing & Mastering, and Stereo Reamp Unit for Driving Guitar / Bass Amps. Improve the sound of DAW’s, Akai MPC X, MPC Live, MPC One, NI Maschine, Isla Instruments S2400, Roland SP-404… The Knock-Boxx allows you to achieve sonic character and flavor much closer to vintage drum-machines (hardware) from the 1990’s era. Run 1990’s era drum machines and samplers thru the MPHC1 Knock-Boxx for unmatched heavy analog sound and tone!

    The MPHC1 is also an expandable, high-powered headphone amp designed specifically for critical studio monitoring. The MPHC1’s circuit employs parallel amp stages for greater power and lower distortion. This parallel-op amp concept has been known in theory for decades and was put to practical use in Douglas Self’s “5532 OpAmplifier” power amplifier. The API style audio transformer delivers a punchy American Console sound, adding beautiful color and saturation. The MPHC1 sounds colorful and clear even at high gain and when driving low-impedance headphones.
