Named after company founder and chief engineer, George ‘Jiri’ Krampera, the JK Series of DI Boxes and
Audio Tools retain KV2’s philosophy of the best possible signal path from source to speaker. The JK Series
consists of the JK1 Single Channel DI, JK2 Stereo DI, JKA Single Channel Acoustic DI with Resonance Notch
Filter and the JKP Single Channel Passive DI and Mic Splitter. Also included in the range is the JKT Tone
Generator, a useful solution-provider audio tool that will assist every engineer in the tuning and checking
of systems and components.
KV2’s JK series represents the pinnacle in DI technology, by offering a higher headroom and lower output
impedance, than any other DI on the market. This simply means the JK Series can deliver crystal clear,
distortion free audio from the hottest sources, without a hint of signal degradation over greater distance.
KV2 has optimized the use of phantom power with a special switching power supply on the JK Series, to
enable an impressive 20 volts of peak power on the internal rails. This allows the JK Series to deliver 50
Ohms on the XLR output giving true line driver capability delivering greater audio integrity and the ability
to send high quality signal four times the distance of it’s nearest competitor.
All JK Series DI boxes are hand built in the Czech Republic utilizing high quality components and
transformers. Full transformer balancing ensures the highest possible signal integrity without interference
from RF or ground loops. The heavy-duty steel enclosure provides maximum protection for the electronics
and further shielding against external interference. KV2 stands by the build quality of these units with a full
5-year warranty.
JK1 - Active DI BOX - Line Driver
The JK1 features two 1/4” jack inputs with mix or parallel function with a variable low cut filter and 15dB
pad. Phase Shift and Ground Lift switches are also available. The JK1 is ideal for connection of single
keyboards, guitars or instrument amplifier output conditioning or combining two inputs via the mix
function.
JK2 - Stereo DI BOX - Line Driver
The JK2 features two 1/4” jack inputs with parallel monitor outputs as well as RCA inputs. The JK2 has two
completely separate channels and can be used with two different instruments or stereo instruments. The
JK2 features a variable Pad, Phase Shift and ground lift.
JKA - Acoustic DI BOX - Line Driver
The JKA is a dedicated DI for acoustic instruments. The JKA features a high-impedance 1/4” jack input
capable of receiving signal from all types of pick-ups. A +10dB gain boost is available for low-level
instruments. The JKA also features a tunable notch filter for eliminating the resonant frequency in an
acoustic instrument, reducing feedback issues.
JKP - Passive DI BOX - Transformer Balanced
Serves as a universal passive DI box with low output impedance. The JKP features one XLR input and two
1/4” jack inputs in parallel. The JKP is dedicated for multiple instruments connection such as keyboards,
guitars or instrument amplifiers output conditioning. The JKP also features phantom power supply
transmission for condenser microphone connection and output signal conditioning.
JKT - Tone Generator
The JKT is the perfect tool for checking and tuning PA systems along with various pieces of equipment.
Phantom powered it has two XLR Outputs and 1/4” Jack Out.
The JKT delivers a full range of tones from 20Hz through to 30kHz, as well as both White Noise and Pink
Noise.
