Palmer havel Active One Channel DI Box

IMPORTANT INFORMATION

Let your signals flow, naturally and powerfully like a river! The River Series embodies this claim down to the last detail:
highly precise switches designed by our award-winning engineers ensure that sound reaches its destination undistorted – the heart 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 developed in 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 that the Havel river flows 334 kilometres through Mecklenburg-Western Pomerania, Brandenburg, Berlin, and Saxony-Anhalt.

2. Danger caused by falling device! Make sure that the device is securely installed and cannot fall down. Only use suitable stands or mounts (particularly for fixed installations). Ensure that accessories are properly installed and secured. Ensure that all applicable safety regulations are observed.

WARNING

1. Use the device in the prescribed manner only.
2. Operate the device only with the accessories recommended and intended by the manufacturer.
3. During installation, observe the safety regulations applicable in your country.
4. After connecting the device, check all cable routes to avoid damage or accidents, for example, due to tripping hazards.
5. Always observe the specified minimum distance to normally flammable materials! Unless explicitly stated, the minimum distance is 0.3 m.

CAUTION:

Moving components such as mounting brackets or other movable components may become jammed.

ATTENTION

1. Do not install or use the device in the vicinity of radiators, heat accumulators, furnaces, or other heat sources. Ensure that the device is always installed in such a way that it is sufficiently cooled and cannot overheat.
2. Do not place any ignition sources such as burning candles near the device.
3. Use the original packaging or packaging provided by the manufacturer for transport.
4. Avoid shock or impact to the device.
5. Observe the IP protection class as well as the ambient conditions such as temperature and humidity according to the specifications.
6. Devices can be continuously further developed. In the event of deviating information on operating conditions, performance, or other device properties between the user manual and the device labelling,the information provided on the device always has priority.
7. The device is not suitable for tropical climates and for operation at heights of 2,000 m above sea level.
8. Unless explicitly stated, the device is not suitable for operation under marine conditions.

PLEASE NOTE: For conversion or retrofit kits supplied by the manufacturer, the enclosed installation instructions must be observed.

CAUTION: HIGH-VOLUME AUDIO PRODUCTS!

This device is designed for professional use. The commercial operation of this device is subject to the applicable national regulations and guidelines for accident prevention.
Hearing damage due to high volume and continuous exposure: use of this product may generate high sound pressure levels (SPLs) that may cause hearing damage. Avoid exposure to high volume

ATTENTION: Connecting signal cables and operating switches (for example, switching phantom power on and off) can cause significant interference noise. Make sure that input channels (mixer, audio interface,  effects device, etc.) are muted while making connections and operating switches. Otherwise, noise levels may cause damage.

WARNING: Unplug the mains adapter from the socket AND disconnect any amplifier that might be connected to the device to put the device in a completely voltage-free state.

ATTENTION: Make sure that the device is not covered while in operation and that the air can freely circulate, especially for the rack mounting!

PLEASE NOTE: Strong magnetic fields can cause humming. For this reason, do not position the device near strong magnetic fields (for example, mains transformer).

PLEASE NOTE FOR PORTABLE INDOOR DEVICES:

1. Temporary operation! Event equipment is generally designed for temporary use only.
2. Continuous operation or permanent installation can impair the functioning of the device and cause premature ageing.

INTRODUCTION

The one-channel DI box havel is a professional studio and stage tool that transforms unbalanced audio signals into balanced audio signals without any distortion. The internal transformer offers an excellent dynamic range and outstanding overload stability. The DI box is used as a connecting link to connect string instruments with pickups (for example, electric acoustic guitars, electric guitars, and electric basses), instruments with line outputs (for example, keyboards), and speaker outputs from guitar amplifiers to balanced inputs of a mixer or audio interface. In addition, the DI box allows for interference-free transmission of audio signals over long cable r

WARNING: Power amplifiers may not be operated in Bridge mode on the DI box.

WARNING: If an amplifier is operated on the DI box, the ground connection between the input and output must be disconnected (switch no. 6 in the unpressed LIFT position).

WARNING: A connected amplifier’s output must not exceed 120 W at 8 ohms!

ATTENTION: If a tube amplifier is used: there is no load resistor in the DI box circuit! To prevent damage to the amplifier, an appropriate guitar speaker or a suitable load resistor must be connected to the THRU jack socket using a speaker cable before switching on the amplifier!

CONNECTIONS AND OPERATING/DISPLAY ELEMENTS – FRONT

INPUT
Audio input with a 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. 3).

THRU
The input signal is output unchanged via the 6.3 mm jack socket.

PAD (passive attenuation device)
Press the corresponding switch to reduce the level of the output signal by 30 dB. The output level must be lowered if the channel input stage of the connected mixer or audio interface is overdriven.

BATTERY COMPARTMENT
Battery compartment for a 9 V block battery. Only use leak-proof brand products. To replace the battery, open the device’s battery compartment by pushing the battery compartment lid’s locking lever downwards and folding the lid forward. Remove the depleted battery and insert a new battery in the battery compartment. Make sure that the battery polarity matches the battery compartment polarity (see marking on the battery compartment lid). Put the battery compartment lid back on the housing until it clicks into place. If you do not use the device for a long period, remove the battery to prevent damage to the device from a leaking battery.

Alternative power supply via phantom power via the OUTPUT XLR socket (48 V). Always make sure that the cable is connected to the audio output and that the channel volume for a connected mixer or audio interface is set to minimum before switching on phantom power. Before disconnecting the cable from the device, turn the channel volume to minimum and then deactivate phantom power.

CONNECTIONS AND OPERATING/DISPLAY ELEMENTS – BACK

LIFT / GND
Switch for disconnecting the ground connection between the input and output (ground lift). The ground connection is disconnected (LIFT) in the unpressed position; the connection is established when the switch is pressed  (GND). The ability to prevent a humming loop using the ground lift switch depends on the grounding of the connected devices. It is therefore possible that either switch position effectively reduces or eliminates humming.

OUTPUT
Balanced audio output with male three-pin XLR socket. Use a balanced, shielded cable (for example, microphone cable) in order connect the DI box to a mixers’ or audio interfaces’ balanced output.

ATTENTION: Connecting signal cables can cause significant interference noise. Make sure that devices connected to the output channel (mixer, audio interface, etc.) and the THRU output are muted while making connections. Otherwise, noise levels may cause damage.
