READ THIS FIRST!
DO NOT HOT PLUG
THE SPEAKERS!
•Please make sure all amps are configured for the mains
voltage of your country (e.g. 230V, 115V).
•To avoid damaging the speakers and voiding your warranty
you have to ensure the following speaker connection
sequence:
1. Connect all XLR cables (1-6)
2. Connect all power cables
Disconnection of the cables needs to be done in reversed
order.
Never connect or disconnect a XLR cable of an already
powered amp since this might damage the speakers! (*)
•It is strongly recommended to not switch the loudspeaker
presets during high listening volumes.
(*) The reason for that is, because we want to have as few parts in the audio chain
as possible to ensure maximum transparency. Due to that, each of our speaker
chassis is directly connected to the amp.

Modular Loudspeaker Systems
1. Introduction
The suter/ohlhorst system is a modular speaker system. It has been developed by the two
engineers Dan Suter (echochamber / Switzerland) and Jan Ohlhorst (finemastering / Germany).
Our approach was to listen and work with as much as possible different speaker chassis, speaker
chassis combinations in various cabinets (closed & ported) with different crossovers & settings in
various rooms. Additionally acoustical measurements have been performed for understanding
and verification.
The system is DSP-based which provides the possibility to tune it to the room and listeners taste.
It is also modular and can be easily extended with additional ways.

2. System Setup
2.1 Input Connection
The input of the Signalprozessor can be connected as analog (left/right) or digital audio.
2.1.1 Analog connection
Connect the XLR output cable for left channel to input 1 and for right channel to input 2 of the
Signalprozessor as shown in the figure below.

2.1.2 Digital connection via AES/EBU
The Signalprozessors digital input accepts digital Signals in the AES/EBU format (110ohm).
Connect the AES XLR cable of your digital Monitor-/Volumecontroller to the Input 2 of the
Signalprozessor as shown in the figure below.

2.2 Output Connection
The amp(s) of each speaker model are directly connected to the Signalprozessors outputs. In the
following the connection of the XLR cables to various Systems is shown.
Please make sure to connect your System as shown in the figures to avoid damaging the
speakers.
2.2.1 System 515
Connect the XLR cables of the Signalprozessors analog outputs (1-4) to the corresponding inputs
of the speaker amp. Make sure to connect as follows:
•Outputs 1/2 are always used for the HIGH speaker chassis (tweeter), where output 1 is for
left and output 2 for the right speaker
•Outputs 3/4 are always used for the MID speaker chassis, where output 3 is for left and
output 4 for the right speaker
•Outputs 5-8 are unused in that configuration

of the speaker amp. Make sure to connect as follows:
•Outputs 1/2 are always used for the HIGH speaker chassis (tweeter), where output 1 is for
left and output 2 for the right speaker
•Outputs 3/4 are always used for the MID speaker chassis, where output 3 is for left and
