Palmer 189732 DI-Box Passive User Manual
Let your signals flow, naturally and powerfully like a river! The River Series embodies this claim down to the last detail: Featuring high-precision circuits, designed by our award-winning engineers to ensure your sound reaches its destination – the hearts of your listeners.
That’s exactly what Palmer® stands for. We have been manufacturing audio tools for professional use on stage, in broadcasting and in the studio since 1980. Musicians and sound engineers around the world value our solutions developedin Germany for their unhindered signal flow and pure sound – as crystal clear and vibrant as water! So what was more logical than naming the River Series models after German rivers?
On the map of Germany you can see where the Wipper flows: 85 kilometres
through Saxony-Anhalt.
Thank you for purchasing the wipper! We hope you enjoy this piece of German
engineering.
Be true to your sound!
Yours, the Palmer Team

INTRODUCTION
The DI box wipper is a professional studio and stage tool that transforms an
unbalanced audio signal into a balanced audio signal. The internal transformer
offers excellent dynamic range and excellent overload stability.
The DI box is used as a link to connect string instruments with pickups such
as electric acoustic guitars, electric guitars and electric basses,
instruments with line outputs such as keyboards, as well as speaker outputs
from guitar amplifiers to balanced mixer inputs or audio interfaces. With the
DI box, audio signals can also be transmitted over long cable runs without
humming.
CONNECTIONS AND OPERATING ELEMENTS
-
INPUT A
Audio input with 6.3 mm jack socket.
A. Connect an instrument using a shielded instrument cable.
B. Connect the speaker output of a guitar amplifier using a speaker cable (tip: Press PAD switch no. 5).
WARNING: Amplifiers must not be operated in bridge mode on the DI box.
WARNING: If an amplifier is operated on the DI box, the ground connection between input and output must be disconnected (switch no. 6 in the non pressed LIFT position).
WARNING: The amplifier output of a connected amplifier must not exceed 120 W at 8 ohms!
ATTENTION: When using a tube amplifier: There is no load resistance in the DI box circuit!
In order to avoid damage to the amplifier, a suitable guitar speaker or a suitable load resistor must be connected to the THRU jack socket using a speaker cable before switching on the amplifier, and switch no. 3 must be in the unpressed LINK OUT position! -
THRU/INPUT B
THRU: The input signal (INPUT A no. 1) is output unchanged via the 6.3 mm jack socket (switch no. 3 in non-pressed position).
INPUT B: In addition to INPUT A, the 6.3 mm jack socket can be used as a second line input (e.g. keyboard L + R); the signals from INPUT A and INPUT B are mono summed and output at the line output OUTPUT (no. 4) (switch no. 3 in pressed position). -
SWITCH THRU/INPUT B
Switch not pressed (THRU): The input signal (INPUT no. 1) is output unchanged via the 6.3 mm THRU/INPUT B jack socket.
Switch pressed (INPUT B): In addition to INPUT A (no. 1), the 6.3 mm THRU/INPUT B jack socket can be used as a second line input. -
OUTPUT
Balanced audio output with a male 3-pin XLR socket. Use a balanced, shielded cable (e.g. microphone cable) to connect the DI box to a balanced input on a mixer or audio interface. -
PAD (Passive Attenuation Device)
Move the switch to the pressed position to lower the level of the output signal level by 30 dB.
Lowering the output level is necessary if the channel input level of the connected mixer or audio interface is distorted. -
LIFT/GND
Switch for disconnecting the ground connection from the input and output (ground lift). In the non-pressed position, the ground connection is disconnected; the connection is established when the switch is pressed. The ability to prevent a humming loop using the ground lift switch depends on the grounding of the connected device. It is therefore possible that both one and the other switch position is able to effectively reduce or eliminate humming
ATTENTION: Connecting signal cables can cause a lot of noise. Make sure that the input channel (mixer, audio interface, etc.) and devices connected to the THRU output are muted when plugging in. Otherwise, noise levels may cause damage.
PLEASE NOTE: STRONG MAGNETIC FIELDS CAN CAUSE HUMMING. THEREFORE, DO NOT POSITION THE DI BOX NEAR STRONG MAGNETIC FIELDS (E.G. MAINS TRANSFORMER).
