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 keyboards and other two channel sources such as
laptops, computers and Ipad. The JK2 features a variable pad, Phase shift
and Ground lift switch.
1. Phantom Power Supply
For ease of use, maximum headroom and low noise the JK2 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. The JK2 can be powered to channel A, channel B or both outputs,
which provides best results.
2. Multiple Inputs
Each channel features two paralleled inputs (A, B) each equipped with 1/4" jack
connectors and stereo RCA inputs on the rear of the unit.
3. GAIN Switch
Using the GAIN switch selector the input sensitivity of the JK2 can be adapted at three levels: 0dB, -12dB, -24dB,
so very high-level inputs can be suitably reduced for clear, distortion-free reproduction.
4. XLR 50ohm Outputs
The JK2 includes two LINE OUT outputs with XLR connectors. Outputs work with
an impedance of 50Ω and it is intended for connection to a mixing desk.
The outputs are 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. The RC position - the grounds for the input
and the output are interconnected via a parallel RC combination. It is used to
suppress static disturbance.
