JK1 · Features
JK1 - part number KVV 987 205
JK1 - Active DI BOX - Line Driver
The JK1 features two 1/4" jack inputs with mix or parallel function with a fixed 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.
1. Phantom Power Supply
For ease of use, maximum headroom and low noise the JK1 is powered by
phantom power from the mixing console. A green LED indicates the presence of
phantom power. Simply switch on phantom power on your console and you are
good to go.
2. Multiple Inputs
The JK1 features two asymmetrical inputs with 1/4" jack connectors. These inputs
can be set as a parallel (input is present on thru), mixed together (inputs placed into
the input and thru are mixed together) or parallel with -15dB attenuation on input.
3. Low Cut Switch
Selects the high pass filter frequency point between 160 and 80Hz. Ideal for
eliminating unwanted bass rumble from instruments.
4. Low Impedance Output
The main symmetrical LINE OUT output has an impedance of 50Ω and it is
Intended for connection to a mixing desk. The output is separated galvanically
from the input.
5. PHASE Switch Selector
Selects between 0° and 180° for LINE OUT output. This switches the XLR
pin-2 and pin-3 to interface with older equipment. Also can be used when
the instrument is being reproduced by the DI and microphone to avoid
cancellation.
6. GND Ground Switch Selector
This ground-lift switch breaks the ground between the input & the output
to eliminate hum and noise caused by ground loops. The GND position - the
grounds for the input and output are interconnected ideal if the signal source
is not grounded. The LIFT position - the grounds for the input and the output
are disconnected. It is used if the signal source is grounded and you are
experiencing ground loop problems.
