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 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 where the Main flows: 527 kilometres through central Germany, where it then flows into the Rhine. Thank you for purchasing the main! We hope you enjoy this piece of German engineering. Be true to your sound!

Yours, the Palmer Team

INTRODUCTION

The main, a passive 2-channel line summing unit, is a professional tool for mixing line signals. Each channel has two balanced XLR/f input sockets. The input signals are mixed via a resistor matrix to an XLR/m output socket. The INPUT 1A / 2A line inputs are also galvanically isolated by transformers. Typical applications are the merging of two mixers to one power amplifier, or mixing a mono signal from a stereo signal.

CONNECTIONS AND OPERATING ELEMENTS

1. INPUT 1A / 1B

Balanced line inputs with female 3-pin XLR connectors. The audio signals of the INPUT 1A and INPUT 1B inputs are summed mono and output at the OUTPUT 1 output.

2. INPUT 2A / 2B

Balanced line inputs with female 3-pin XLR connectors. The audio signals of the INPUT 2A and INPUT 2B inputs are summed mono and output at the OUTPUT 2 output.

3. OUTPUT 1 / 2

Balanced line outputs with male 3-pin XLR connectors. Use a balanced audio cable (e.g. microphone cable) to connect the summing unit to a balanced input of a mixing console or audio interface.

4. LIFT / GND 1 - LIFT / GND 2

Switch for disconnecting the ground connection of input and output of the corresponding channel (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 the switch is able to effectively reduce or eliminate humming when it is either up or down, depending on circumstances.

CAUTION: Connecting signal cables can cause considerable noise. Please make sure that the input channels of mixing console and audio interfaces, etc. are muted when plugged in. Otherwise, noise levels may cause damage.

NOTE: Strong magnetic fields can cause humming. Therefore, do not position the line summing unit near strong magnetic fields (e.g. mains transformer).
