Interacts intelligently with Multi-
band, to easily achieve desired
loudness. Tight, punchy, 
abundant bass is unmatched.
2020MkII is the only processor
that holds voice equal in 
loudness to music program.

Perfect pilot protection with no 
spurious output. Extended high
frequencies & transients for a 
natural, open sound without
harshness or edginess. Better
sound and better coverage.

Perfect modulation - no need for
composite clipping. Accurate,
wide, stable stereo image. 
Proven extended coverage.**

The Model 2020MkII is totally controllable locally 
via the front panel controls or remotely via RS232 
and modem. The newly improved Remote Software 
is Windows

®

98 & 2000 compatible. 

The 2020MkII has eight factory presets and 16
user definable presets. All operating parameters 
can be modified and saved in a user preset. 
Day parting can be programmed for up to four 
changes of presets per day. In addition, each day 
of the week can be programmed to have its own 
day parting schedule of presets.

The basic unit has flat (no pre-emphasis) processing 
with analog I/O. Option 1 adds AES/EBU digital I/O.
Option 2 adds a pre-emphasis limiter and low pass 
filter. Option 3 adds the pre-emphasis limiter, low 
pass filter and PPDM stereo generator. Option 4 
adds an Ultra-precision oven-controlled crystal 
oscillator to Option 3.

Competition for loudness impacts audio quality. The 2020MkII

rewrites that formula through the utilization of 18 exclusive

techniques (patented and patent pending) which increase 

density beyond any other processor while retaining naturalness

and musicality.

Another advantage of the 2020MkII is the stability and purity of

the signal, resulting in extended coverage and more consistent

coverage in shadow areas.

The 2020MkII comes with 8 sample presets that many will find

perfect for their station’s sound. Others will find these suitable

as the starting point to completely customize a sonic signature

from the vast palette of control over processing parameters.
