Software Control Settings

Next up are the LS1r Controller settings. Here you can control the brightness of the LS1r

Controller display. Additionally you can choose whether pressing the big volume dial activates the

MUTE or the DIM function and if the display shows the volume, the input source or nothing at all.

One tab to the right you will nd the Pro Settings page. These are in general only useful for

professional audio engineers.

The rst option is the Midi connection settings. If a Grimm Audio USB interface is connected to

your computer, it is usually automatically selected by the LS1 remote software. Otherwise you

can select it from the drop down menu. If you use a DAW controller with a control room fader

that transmits midi volume data, it can replace the LS1r Controller. In that case select the DAW

controller (or an associated virtual midi channel) for input data and the LS1 USB interface for

output data. If you do not own the LS1 USB interface, you can also use a generic midi interface

to communicate with the LS1. Grimm Audio can supply a ’midi to Grimm cat5‘ conversion box to

you.

Display zero reference - In this section the reference levels 1 and 2 can either be set or restored

to default. The default ’0‘ level is equal to the international reference used in mastering.

Technically speaking, at the reference level a reference noise of -20 dBFSrms will give you an

acoustical level at the listening seat of 79 dBC. This was called ’K14‘ by mastering engineer Bob

Katz and is the level where nineties pop music was mastered at. In more recent days pop music

masters have become considerably louder and you probably have to adjust your volume control

to lower levels for a comfortable monitoring level. In any case it is very good practice to work at

standard playback levels or at least regularly check you mix or master at reference level.

Since results are dependent on room acoustics, you probably have to adjust the 0 dB position

of your volume control to the correct level. Please measure the acoustic level of the reference

noise in your room at the listing position with a professional sound level meter. Adjust the volume

control for 79 dBC. You may now program this as your ’reference‘ 0 dB level in the software by

clicking the ’Current level to Ref 1‘ button. The display on the left indicates the offset you have

relative to the factory default level. If you now like to quickly set the volume control to the stored

0 dB reference, just double click the Ref 1 button in the main window. To use a second reference

level at a lower or higher gain position, you can store it as ’Ref 2‘ by setting the volume to your

preferred second reference level and then clicking ’Current level to Ref 2‘. You can always click

’restore default‘ to go back to the factory levels.
