General equalisation
ADAPTING THE SYSTEM TO THE LISTENING ENVIRONMENT
General equalisation is possible (except on the Sub channel) via 3 fully programmable parametric EQ’s , which can be individually set in amplitude, frequency and quality factor ("Q").
A
Digital Input Mode
When the digital input is used, it is possible to actually get the mono sum of the two ("Left" and "Right") audio channels transmitted via the AES connection.
This option is available for the Sub: it is referred to as "2.1 (L+R)" as opposed to "5.1 (LFE)", which is the default mode of operation where only one input channel is used (depending on the position of the CHANNEL switch located at the back of the unit).
It is also available for the Left and Right speakers; the option is called "Mono L+R" and appears in the Master level menu.
Delays
Variable delays (up to 10 ms) can be assigned to groups of channels: Left/Right, Centre, Left/Right surround, and Sub. This allows precise time alignment tailored to actual positioning of the loudspeakers with regard to the listening position.
Subwoofer polarity
The polarity of the Subwoofer channel can be inverted by software. This can be useful, for example, when one desire to use a combination of 24 dB/oct and 12dB/oct to crossover the subwoofer. It is also a good practice, when adjusting delays and/or crossover frequencies, to invert the polarity of the Sub, search for the widest cancellation, then turn the polarity back on to normal.
Presets
Presets are a convenient way of dealing with a number of parameters as a whole, being able to save them under a specific name. Actually, a preset contains the values of the various parameters for all channels: delays, shelving, PEQ, and so on… Once created, a preset can be stored, reloaded and sent to the speaker system, edited, and deleted.
