Genelec SE7261A

System

Genelec SE7261A DSP Subwoofer is designed for precise monitoring of 24 bit/192 kHz AES/EBU digital audio signal. It is fully compatible with Genelec GLM.SE Loudspeaker Manager Software and the proprietary Genelec loudspeaker control network and Genelec 8130A digital input loudspeakers.

The SE7261A can perfrom bass management. The DSP bass management system splits the signal from each input into low and high frequency components. Signal content below the crossover frequency is reproduced by the subwoofer and signal content above the crossover frequency is reproduced by the loudspeakers contented to the outputs of the subwoofer.

Before connecting the audio signal cables, ensure that both the subwoofer and the main loudspeakers are switched off. Connections are easier s to make if you roll the subwoofer on its side with the connector panel facing up. Use this position only for making the connections and roll the subwoofer back to its normal upright position before use.

If the frequency balance is not right, try moving the subwoofer slightly to the left or right so that different room modes are excited at different levels. Positioning the subwoofer close to a corner will boost the bass level at lower frequencies and may cause asymmetrical spatial imaging.

If you are using two subwoofers, try placing them asymmetrically relative to the side walls. Some times moving the subwoofers apart into the front corners helps with problematic rear wall reflections and the loss of manual coupling is compensated by the bass boost caused by corner positioning.

LFE Bandwidth

The LFE input can be set to two frequency rangers: 19 to 85 Hz or 19 to 120 Hz using the “LFE BANDWIDTH” switch. Signal content in the LFE signal above the frequency value selected on the “LFE BANDWIDTH” switch is either not reproduced or is redirected (see below). See also “Typical applications of different LFE bandwidth settings” below.
