This depends entirely on your taste and the venue and 

objective for the recording. However, for the best recording 

possible, the midrange should be kept flat. This will give the 

truest indication of  the response and of  any EQ previously 

done to the recording.  

 

 

You can get a reasonable approximation of  the frequency 

response, but there is more to replicating a speaker than its 

frequency response. For example, certain drivers (e.g. woofers) 

may have good transient response. Others may not. Both 

could yield the same steady state (continuous tone) response 

but sound completely different to something with a fast 

transient response such as a snare drum or clapping.  By 

popular demand, one of  the Presets is modeled after the 

ubiquitous black monitor with white cones, but it is a rough 

approximation. There are two other speaker responses that are 

emulated, as well. See if  you can figure out their identities! 

 

 

The level control on the back attenuates the input signal to the 

speaker.  The Gain Trim control attenuates or boosts the 

output of  the DSP.  For large source signals you want to 

attenuate the input level so as to avoid saturating (clipping) the 

input Analog to Digital converter (ADC). The Gain Trim 

control should be adjusted to avoid saturating the output 

Digital to Analog converter (DAC). This must be done by 

listening for output distortion. The user should also be careful 

to avoid setting the attenuation levels too low, as this could 

lead to a loss of  resolution as well as a higher noise floor.  

 

To assist you with these adjustments, the ProLinear DSP 

provides the ability to monitor the input level to the ADC on 

the front panel display. For instructions on how to do this, see
