Frequently Asked Questions - Enz Palmer

What is the function of the Ground/Lift switch on the Palmer Enz?

The Ground/Lift switch allows you to disconnect the ground connection (Lift position) or restore it (GND position). This eliminates ground loops and parasitic hum caused by potential differences between connected devices.

Does the Palmer Enz require electrical power?

No, the Palmer Enz is a passive line isolator. It does not require any external power: it works solely from the transmitted audio signal.

What cables should I use to connect the Palmer Enz?

Use good quality shielded Cinch (RCA) cables. For input, connect your source (computer, sound card) to the INPUT LEFT/RIGHT jacks. For output, connect the OUTPUT LEFT/RIGHT jacks to the mixer or audio interface.

Can I use the Palmer Enz with balanced signals (XLR)?

The Palmer Enz is designed for unbalanced signals on RCA connectors. To use balanced signals, you will need an adapter or a different type of isolator.

How to clean the housing of the Palmer Enz?

Disconnect all cables. Wipe the housing with a soft, dry cloth. Do not use water, solvents, or abrasive products.

What to do if there is buzzing or humming after connection?

First check that the Ground/Lift switch is in the LIFT position to disconnect ground. If the humming persists, try the other position. Also ensure the cables are shielded and that the device is not placed near a transformer or magnetic field source.

Can the Palmer Enz be used outdoors?

Yes, within the temperature range of -20 °C to 70 °C, provided that humidity is below 80% without condensation. It is intended for professional use on stage or outdoors.

Are spare parts available for the Palmer Enz?

The Palmer Enz is a robust device with no consumable parts. In case of failure, contact your dealer or the manufacturer (Adam Hall GmbH) for warranty repair or a quote.

What is the warranty of the Palmer Enz?

The warranty is provided by Adam Hall GmbH. Terms are available on their website: see the declaration. In case of issues, contact your business partner.

How to dispose of the Palmer Enz at end of life?

Do not dispose of it with household waste. In accordance with the WEEE directive, take it to an approved collection point for electrical and electronic equipment, or return it to your dealer.

INTRODUCTION

Two-channel separator (line isolator). Equipped with RCA inputs and outputs, the Line Isolation Box enz is specially designed for connecting notebooks and sound cards to mixers, etc. Use the ground lift switch to disconnect the ground connection from the input and output to eliminate hum loops and other interference signals that can be caused by computers, for example.

CONNECTIONS AND OPERATING ELEMENTS

1. INPUT LEFT/RIGHT

Unbalanced stereo line input with two RCA (cinch) sockets. Use a shielded stereo audio cable, for example to connect a notebook to the Line Isolation Box.

2. OUTPUT LEFT/RIGHT

Unbalanced stereo line output with two RCA (cinch) sockets. Use a shielded stereo audio cable to connect the Line Isolation Box to an unbalanced stereo input on a mixer or audio interface.

3. 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 devices. 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 input channels from mixers and audio interfaces etc. are muted during plugging. Otherwise, noise levels may cause damage.

PLEASE NOTE: Strong magnetic fields can cause humming. Therefore, do not position the Line Insulation Box near strong magnetic fields (e.g. mains transformer).
