Overview Tab

Overview
Displays an overview of the output channel settings including Delay, DCA and Mute Group Assigns, Pre/Post pick-off points (auxiliaries only), Aux
Send Levels (see Matrix Mixing).

PEQ Tab

PEQ
Six-band parametric EQ with High / Low-Cut filters and a Real Time Analyzer (RTA)
This tab displays the six-band, parametric equalizer plus the Low and High-Cut Filters. The 6 bands of parametric EQ can be individually bypassed
using the numbered buttons. Bands 1 and 6 may be switched from parametric to shelving operation. You can use the two-finger pinch / zoom
gesture to adjust the Q for the selected Band.
RTA On
Touch the button to activate / deactivate a Real Time Analyzer display for the channel. ("Real-time Analyzer
(RTA)" on page 97).
NOTE!: When the RTA is not enabled, the Parametric EQ screen is enlarged to occupy both the RTA and PEQ screen area.
Low-Cut / High-Cut filters – These filters are used to roll off high or low frequency content. There are a number of possible applications.
• For stage monitors, it is common to roll off low frequencies at 80 – 100 Hz. There is usually ample low frequency energy on stage without any
help from the monitors. Keeping it out of the monitors can reduce "rumble" on stage and in the house.
• For speech only systems, rolling off low frequencies can reduce microphone handling noise or, if outdoors wind noise.
• Fill speakers may not need any additional low-frequency energy as there is ample bottom end coming from subwoofers.
• There is a technique known as "subs on auxes" in which the subwoofer is fed from one of the auxes while the main speakers are fed from the
mixer's main outputs. Only those instruments that contain low-frequencies are sent to the subwoofer. This provides more control over the lows
and can help keep the bottom end tighter. If this is being done, the Low and High-Cut filters could be used to set the crossover point between
subs and main speakers.

GEQ Tab

GEQ
One-third octave graphic equalizer with an RTA
In addition to the Real Time Analyzer (RTA), this tab displays two, overlaid 1/3 octave graphic equalizers.
• GEQ: The solid faders [Insert Image] control the user adjustable graphic equalizer. The "GEQ" switch may be used to bypass (Out) or activate
(In) this equalizer. The "Reset" button will return the GEQ sliders to 0.
• Tuning Wizard EQ: If the "Tuning" switch is set to "In" a set of 'ghost' faders
(1) is displayed to indicate the settings resulting from adjustment by the Room
Tuning Wizard (See "Room Tuning Wizard" on page
indicators only and are not adjustable.
The GEQ and the Tuning Wizard EQ are additive. So 3 dB boost from the Tuning Wizard
and a 2 dB boost from the GEQ at the same frequency will result in a 5 dB total boost.
