Der K&K Sound Pure Preamp ist ein kompakter externer Vorverstärker, der entwickelt wurde, um das Signal von Akustikgitarren-Pickups und anderen passiven Tonabnehmern zu verbessern. Er bietet eine rauscharme Schaltung mit einer dreibändigen Klangregelung (Bass, Mitten und Höhen) sowie ein internes Gain-Trimmpoti zur Anpassung der Verstärkung. Der spezielle Breitband-Mittenfilter und die hohe Eingangsimpedanz sorgen für eine natürliche, breitbandige Wiedergabe von 10 Hz bis 30 kHz, was ihn besonders effektiv mit Piezo-Pickups macht. Der Pure Preamp wird mit einer 9-V-Batterie betrieben und bietet mit seiner robusten Belt-Clip-Bauform klare, kraftvolle Klänge und einfache Klangformung.

The K&K Sound Pure Preamp is a compact external preamplifier designed to enhance the signal from acoustic guitar pickups and other passive transducers. It features a clean, low-noise circuit with three-band EQ controls (bass, mid, and treble) and an internal gain trim that lets you adjust the amplification from subtle to stronger boosts. Its wide-band midrange filter and high input impedance provide a natural, full-range response from 10 Hz to 30 kHz, making it especially effective with piezo pickups. Powered by a 9 V battery with long life and housed in a rugged belt-clip case, it delivers clarity, power, and simple tonal shaping in a small form factor.

Manual

Pure Preamp

The external Trinity Pro Preamp allows for individual sound adjustment of the mic and pickup. It is built using K&K's "silent filter technology" and our full size component philosophy. We use full size capacitors and other parts because we find they sound better than the miniature components in most of our competitors' preamps. This little preamp is extremely versatile and powerful and features easily accessible volume controls and internally adjustable gain/EQ controls with +/- 20 dB bass, midrange and treble filters (trimpots) for each individual channel, plus a phase switch for the microphone channel.

Trinity Pro Mini System

The Quantum Blender is our top-of-the-line two-channel preamp/mixer that provides all the control and features you could ever want to combine a piezo transducer with a microphone, magnetic pickup, or another piezo pickup.

Channel 1 is switchable between microphone and pickup impedance. This means it can be used with any 2-wire powered lavalier type condenser mic or with a piezo or magnetic pickup. A dynamic mic can be used as well with an appropriate microphone impedance matching transformer. Channel 2 is designed with K&K's Pure pickup in mind, but it works well with most piezo transducers.
