In the previous illustration, each control element is associated with a 
callout, for example . To identify details about each control element 
in this documentation, use these callouts. The numeric order of these 
callouts identifies the FBQ800 signal path.

(1) 

� (POWER) button: To turn the FBQ800 on and off, use this 

button, which can appear:

pushed in and illuminated: The FBQ800 is on.

not pushed in and not illuminated: The FBQ800 is off.

(2) 

IN/OUT button: To activate or, alternatively deactivate control 
elements, use this button, which can appear:

pushed in and illuminated: The FBQ800 activates all 
control elements.

not pushed in and not illuminated: The FBQ800 
deactivates most control elements. However, you can use 
the METER SELECT button  

(5)

  and the IN/OUT meter  

(6)

.

If you activated all control elements  

(2)

, you can use control elements  

(3)

  and  

(4)

  to prepare the input signal for EQing, as follows:

(3) 

LEVEL CONTROL: To adjust the level of the input signal, turn 
this control toward -12 dB (minimum setting) or, alternatively 
+12 dB (maximum setting). Some signals have high levels that 
can deteriorate sound and equipment.
For details about managing the signal level, see  

(6)

  How to 

manage the signal level.

(4) 

LOW CUT button: To manage the low-cut filter, use this button, 
which can appear:

pushed in and illuminated: The low-cut filter eliminates 
sounds that are below 75 Hz (floor rumble, room 
resonance, and mains hum, for example).

not pushed in and not illuminated: The low-cut filter does 
not eliminate any sounds.

To monitor the input signal or, alternatively the output signal, 
use control elements  

(5)

  and  

(6)

, as follows:

(5) 

METER SELECT button: To select the type of signal you want to 
monitor, use this button, which can appear:

pushed in and illuminated: Monitor the input signal as 
soon as this signal enters the FBQ800. The FBQ800 does 
not apply the LEVEL control or any other control elements 
to the input signal that you monitor.

not pushed in and not illuminated: Monitor the 
output signal as soon as this signal leaves the FBQ800. 
The FBQ800 applies all control elements to the output 
signal that you monitor. However, if you deactivated most 
of the control elements  

(2)

, the input signal and the 

output signal are the same.

(6) 

IN/OUT METER: To monitor the level of the signal that you 
selected with the METER SELECT button, use this stereo meter. 
Both the left (L) and right (R) sides of this meter share the same 
decibel scale (-24 dB to +6 dB). If the signal level is too high, 
the CLIP LED illuminates.

At 0 (zero) dB, the FBQ800 still has approximately 15 dB of 
headroom. How to manage the signal level
Optimally, you want to maintain the signal level of the FBQ800 
at 0 dB. When the signal level is:

less than 0 dB, the signal is not full. If the difference 
between the level of the noise floor and the level of the 
signal is not sufficient, you lose signal quality.

greater than 0 dB, the CLIP LED illuminates on the 
IN/OUT meter. The signal can overload the FBQ800. 
However, occasional clipping will not damage the 
sound quality.

Because sounds are not perfectly consistent, you cannot flawlessly 
maintain the signal level at 0 dB. However, you can consistently 
manage the signal level. This involves monitoring and adjusting the 
level of the input signal and the output signal, as follows:
1.  To begin EQing in a neutral environment, set all frequency-band 

faders  

(9)

  to 0 dB.

2.  To protect the FBQ800 against signals that are unexpectedly 

high, turn the LEVEL control  

(3)

  to -12 dB.

3.  To monitor the input level, use the METER SELECT button  

(5)

  together with the IN/OUT meter  

(6)

, as described in this 

documentation. If the input level is higher or lower than 0 dB 
and you:

can adjust the output level of the input source, adjust the 
output level of the input source until the input level 
of the FBQ800 is 0 dB

cannot adjust the output level of the input source, set the 
output level of the FBQ800 to 0 dB, as follows:
A.  To activate all control elements, use the IN/OUT 

button
