17. RTA button

Pressing this button engages the real time analysis

function, and lights the button solid. The RTA looks at
the input signal of the currently-selected channel. It is
not related to the external measurement mic input. The
RTA and MIC buttons operate in an exclusive manner,
meaning only one can be active at any given time.

The 30 LED ladders display the levels of the currently

selected channel. The ladders are then like a graph of
the received signal’s frequencies from 20 Hz to 20 kHz,
split up into 30 bands, vs. the signal level of each band.

RTA EDIT functions

There are four options for the RTA described below:

1. Press EDIT [13] (blinks) and RTA (blinks) to

get to the first option shown in the DISPLAY
[20]. Use the KNOB [19] to adjust its param-
eter.

2. Each time you press RTA, you move to the next

option to be adjusted, The options are as fol-
lows, in the order in which they appear: REF,
DCY, EQ, and EQD.

3. Press the KNOB or EDIT to exit the edit mode.

REF (Reference level)

This option allows you to adjust the RTA reference
level (–60 dB to 0 dB) with the KNOB. This allows
you to get the analyzed signal into the best range for
viewing on the LED ladders.

If you turn the KNOB a little, you can press and hold
the RTA button to auto-reference level the RTA. This
will take an average of the analyzed signal and set
the reference level automatically.

DCY (RTA decay)

This option provides 4 decay settings for the RTA you
can choose with the KNOB:

• Off is straight metering of the signal.
• On1 displays metering plus a peak-and-hold

function with a slow decay.

• On2 displays metering plus a peak-and-hold

with a fast decay.

• On3 is a peak-and-hold with no decay.

EQ (pre/post EQ RTA analysis)

This option allows the RTA to be applied to the input
signal either pre-EQ or post-EQ.

A pre-EQ RTA signal is great way to view the signal
as it enters the EQ. This can be used to see the
frequency response of the raw signal coming into the
Quad EQ.

The post-EQ setting (the factory default) is very
valuable, as the RTA will respond to filter changes.
This can be useful for graphic EQs for monitor wedge
mixes. A feedback frequency can be easily identified
and cut using the Quad EQ in this way.

EQD (EQ display)

This option allows you to turn off the EQ filter set-
ting display during RTA operation, so you can oper-
ate the device purely as an RTA.

Although the EQ filters are still applied to the signal,
the display only shows RTA information.

If you have turned off the EQ display with this fun-
tion, it will still come back on for a few seconds each
time you press or adjust a filter EQ. This reminds you
what the EQ settings were, even when the display
has been turned off.
