Model Specific Information General Currently there are seven models in the PARAMEDIC Series Each model adds features to those of the basic PARAMEDIC as follows 1 The Basic ParaMenic 70 filters that can be software configured as parametric high or low pass high or low shelving one third or one sixth octave T models add input and output transformers 2 ParaMebic The PARAMEDIC adds digital delay to each output T models add input and output transformers 3 ParaMepic A The PARAMEDIC X adds digital delay to each output two way crossover function peak limiting function to each output T models add input and output transformers d ParaMevic Code Pink This model is mission specific to speech privacy masking applications It is also appropriate for applications requiring a basic PARAMEDIC with built in white pink noise for sound system testing The PARAMEDIC Code Pink adds two digital white pink noise generators Software generated default pre built one third octave filters to each output T models add input and output transformers 5 ParaMenic 22 2 Outputs 6 ParaMevic 24 4 Outputs 7 ParaMenic 26 6 Outputs These models PM22 24 amp 26 add the following features to the PARAMEDIC X but should be considered in a league of their own 2 4 or 6 Outputs Choice of XLR or Phoenix type audio connectors LOO parametric filter capacity Allpass filter filter l

When threshold is reached on one limiter all others will respond accordingly e Group crossover sections together This creates a separate group for each stereo channel s low pass band pass and high pass crossover section The advantage of this scheme is multi band limiting If either channel s low pass output reaches threshold limiting will only occur on the low pass outputs The high pass and band pass if any outputs will be left alone The outputs can also be ganged in up to three gangs for purposes of level adjustment You might consider ganging the left and right low pass sections the left and right band pass sections if any and the left and right high pass sections Mono Operation The PARAMEDICs feature true mono summation of a stereo input signal This 1s accomplished by assigning each input to all outputs in the matrix mixer The inputs can be linked to simultaneously create and adjust duplicate filters that are appropriate to all outputs Their level controls can also be ganged As many crossover sections as there are outputs can be created Outputs without crossover sections can be full range or band limited by creating a single crossover section on these outputs If you apply limiters to the bandlimited output sections but DO NOT group them you will enjoy the advantages of multi band limiting The outputs can also be ganged in up to three groups for purposes of level adjustment z z This is a block di Auditorium
