than the overshoot amount, and that it will not introduce harsh artifacts. The second stage is 
a unique program limiter featuring Intelligent Predictive Limiting™. Its function is to monitor 
the input signal and intelligently predict the amount of gain reduction needed to keep the 
output signal below the ceiling set by the Instantaneous Transient Clamp™. Note that since the 
PeakStop+™ limiter is a fail-safe limiter, it must come after the OUTPUT GAIN control.

This parameter sets the amount of overshoot for the Instantaneous Transient Clamp™ when 
PeakStop+ is turned on. 

The DriveRack 260 offers pre-crosssover and post-crossover alignment delay. The post-crossover 
Delay modules can be used for delay compensation when speaker drivers are offset from one 
another, compensation for the difference in high and low frequency speed, and delay fills. The 
pre-crossover Delay modules can be used for delaying the system as a whole, without having 
to readjust each post-crossover delay module. The parameters for the alignment delay are as 
follows and are user adjustable:

Turns the Delay module on and off.

Sets the amount of speaker alignment delay time. Delay times include: 
•  Seconds - 0.00 to 1.3
•  Feet - 0 to 1465.1
•  Meters - 0 to 445.9 

 Note: The delay time must be allocated to be available. See section 3.5 ‘Creating a User  
 

Configuration’ for information on allocating delay.

Selects the unit of measurement for the delay.

The signal routing begins at the INPUT ROUTING block of the 260. There are two input routing 
mixers; they are ‘A’ and ‘B’. These input routing mixers allow you to mix any combination of 
input channels, 1 and 2, for greater flexibility in routing. Generally, by default, input Ch. 1 
corresponds to input mixer ‘A’ and input Ch. 2 corresponds to input mixer ‘B’, however this 
can be changed. For example, inputs 1 and 2 could be mono summed to the ‘A’ mixer for a 
mono front of house system, while the ‘B’ mixer also receives a mono summed signal, from 
inputs 1 and 2, but feeds a delay or balcony fill. The power in such a setup is that each input 
routing mixer, ‘A’ and ‘B’, could have completely independent input signal processing chains 
and parameters. Therefore, in such a configuration, the user could Auto EQ the front of house 
system (input mixer ‘A’ chain) independently from the delay fills (input mixer ‘B chain) and 
apply feedback suppression to only the front of house system, while not affecting the delay 
fills. Each input routing mixer (‘A’ and ‘B’) contains the following parameters, which are user 
adjustable on all programs.
