10Speaker sets

The speaker sets can be labeled individually. Simply click in the text field and enter a name of your choice.

Assigning an output to a speaker set

With no bass management an output is assigned directly to a speaker set by checking the ASSIGN check box for the output.

However, when bass management is used you must set main speakers to “main” and sub to “sub”.

11Trim

Range: -20 dB to 0 dB

Individual trim levels for each channel.

12DLY

Range: 0 to 30 ms

Perfect listening conditions and placement of speakers according to an ITU 775 circle are not always possible. This delay parameter allows for individual alignment of speakers.

13Output label

The physical outputs have fixed names according to the labels on the rear panel. However, you can also add an additional personal label to these channel

outputs.

Bass management

The bass management system is designed to subtract the bass contents of all main channels and reproduce this by the use of a subwoofer and is easily set up with the Studio Konnekt 48.

Let us take at look at the components and how to set up bass management using the Studio Konnekt 48.

The Subwoofer

A subwoofer is a monitor that reproduces low frequencies. The purpose is to take over from the main monitor(s) as frequencies approach the lower end of the monitors frequency range. Depending on the performance and size of the main monitors the used threshold frequency between main monitors an sub, may vary from 80 to 120 Hz. From psycho-acoustics we know that there is no directional information in audio signals below approximately 120 Hz. Hence the advantage of placing the subwoofer in a position where the best distribution is achieved.

The LFE Channel

LFE is short for Low Frequency Enhancement or Low Frequency Effects, the first being the original name but the second being the most correct with regards to its application.

It is also referred to as the “.1”-channel, which indicates that the frequency range of this channel is only a fraction of the other channels in a multi-channel setup. The actual frequency range is 20 Hz to 120 Hz.
