CHECKING - PLACEMENT OF THE MONITORS

Equalizing

The AIR System menu offers a two-band shelving type equalizer. This can be used individually on each monitor, and it is implemented for a fine adjustment of the tonal balance.

Range:	±6 dB
Adjustment step:	0.5 dB
Band I:	100 Hz - 1 kHz
Band II:	1 kHz - 5 kHz
Filter type:	Shelving

You should be very careful using this tool if you are doing the adjustment by ear. In a room with good acoustics equalizing should not be necessary at all.

As a test signal you can use full bandwidth pink noise (tracks 2 or 13) on the test-CD

In a room that you feel heavily over damped at higher frequencies you may wish to ad some level in the high end in order to get the right balance. Do it with care then.

In a highly reflective room you may wish to attenuate the high frequencies.

If you have made a good job placing the monitor in a proper position you should not touch the low frequency band.

Notice: If you have done any adjustments using the equalizer, you should leave the room and come back 15 minutes later bringing some music, that you know well. Play this music. Now your first impression is very important for the assessment of the tonal balance of the monitor system. Listening during a long time will make the hearing perform a change in the perceived timbre. This is what we can compare to the "white balance" of the eye. After a short time you are getting used to a new tonal balance or timbre. What sounds "cool" or "fat" then is not necessarily sounding right for monitoring purposes.

Additional Equalizing can be done via the optional

PC-IP Installers Software.

PC-IP- Advanced Installers PC - Interface Packages The Installers software includes a 4 band Parametric EQ, for more precise EQ adjustment of each monitor.
