Please read all instructions before using this device.
Never use the device near water, i.e. next to a bathtub, sink, or drain, in a damp
basement or near a swimming pool.
Used in combination with an amplifier and headphones or speakers, this device can
cause sound levels that may result in lasting hearing damage. Avoid long exposure to
excessive or unpleasantly high volume levels. Consult an ear specialist immediately if
you detect a loss of hearing or a ringing in your ears.
Ensure adequate ventilation for the device when setting it up.
Do not install it near sources of heat such as radiators, ovens or similar devices.
Ensure that the device is connected only to a standard AC outlet.
Position it in such a manner that no dust, liquids or foreign objects can enter the hous-
ing.
Unplug the external power supply from the AC outlet if you do not intend to use the
device for an extended period.
The device must be serviced by trained personnel if:
o the external power supply is damaged,
o objects or liquids have entered the device,
o the device was left in the rain,
o the device was damaged by dropping,
o the device is malfunctioning.
Do not attempt to repair the device yourself. Please consult a trained technician.
Please ensure that all analog devices are turned off before plugging them in. This will
protect you from any possible—albeit weak—electrical shocks, as well as protecting
your speakers and your hearing from sudden peaks. For digital devices, be sure to at
least lower the volume on your playback equipment.

SINE DI 4
Connections and controls
The front panel:
1. INPUT: Input socket (1/4" mono jack)
2. LINK-OUT: Output for direct signal feed-through
3. -20 dB attenuation
4. -40 dB attenuation (only in conjunction with –20 dB attenuation)
5. GROUND-LIFT: Ground isolation of the signal
6. 12 V AC: AC power
The rear panel:
7. POWER: Power switch
8. 12 V AC: AC power
9. OUTPUT: Balanced output, XLR
10. INPUT: Input socket (1/4" mono jack)
6 SINE DI 4 / SINE DI 8 (English)

Function
The SINE DI 4 rack system is an active direct injection box that converts unbalanced line
signals to balanced signals. Apply an unbalanced line signal to the input on the front or
rear panel to get a balanced signal at the XLR output. The signal is also fed through un-
changed to the Link-Out socket.
You can also attenuate the signal by –20 dB or –40 dB.
And if you're being annoyed by hum pickup, use the ground lift switch to fully isolate the
input and output signals from one another.
Note: do not connect two sources (front and back) to the same input channel. This
may damage the device.
Technical data
Audio inputs: 4 x 1/4" unbalanced jacks, front panel
4 x 1/4" unbalanced jacks, rear panel (parallel to front panel)
Input impedance: 470 ohm
Audio outputs: 4 x XLR, balanced, rear panel
4 x Link-Out, unbalanced, front panel
Output impedance: 1 kohm
Frequency response: 25 Hz – 20 kHz
AC power: 12V AC, 700 mA
Dimensions: 482.6 x 87 x 44 mm (19”, 1U)

8 SINE DI 4 / SINE DI 8 (English)

Function
The SINE DI 8 rack system is a passive direct injection box which does not require a
dedicated power supply. The primary application of the SINE DI 8 is the isolation of input
and output signals (synthesizers, mixers, etc.). This is partly realized by interrupting the
ground connection of the signal that frequently causes hum pickup. For example, to iso-
late the connection between a synthesizer and mixer, connect the synthesizer to one of
the 8 inputs of the DI 8. Next, connect the associated output of the DI 8 to the mixer input.
You can also attenuate the signal by -20 dB.
Note: do not connect two sources (front and back) to the same input channel. This
may damage the device.
