Overview
This section of the menu is dedicated to the fi ne tuning of different signal levels routed through or
processed by the Evolution 707. This menu is broken into several sections focusing on specifi c signal
requirements or decoding modes.
Device Trim
Device trim is a master level adjustment for all of the incoming audio signals. This tool is useful when
trying to balance the overall level from input to input while switching preset buttons. The device trim
range is from -15dB to +15dB in 1dB increments.
Analog Input Trim
An adjustment of analog input signals utilizing a clip indicator to display and adjust the incoming
signal level for fi ne tuning. Often there are analog signals that have exceptionally high output that
may overload or clip the Evolution 707's input stage. This would require the input trim or even the
Anti-clip circuit.
NOTE: A Device with an analog source confi gured needs to be selected fi rst in order to enable the
Analog input trim function. Select the device button preset and proceed to the OSD Menu.
A. Anti-Clip - The anti-clip function measures the signal level and prevents the input signal
from overloading (clipping) the analog-to-digital converters. The Anti-clip option is ON or
OFF.
B. Input Gain – Increase or decreases the analog input signal for optimum performance. The
input gain range is from -6dB to +6dB in 1dB increments. To maximize your system's signal-
to-noise ratio without clipping, increase the input gain value applied to the signal until
you see the clip indicator Labeled "LEFT and RIGHT" illuminate on the screen; then back the
input gain value off 1 dB.
Music Mode Sub Trim
The music mode sub trim allows a subwoofer level adjustment for use with the custom Krell music
surround or DTS surround modes. This is a permanent fi ne adjustment made at the device level
as opposed to the main subwoofer levels set in speaker setup. These adjustments do not change
the main settings. The music mode sub trim adjustment range is from -10 dB to +10dB in 1dB
increments.
DTS Control Trim
DTS NEO surround modes take a 2 channel audio input and create 5.1 surround channels. DTS
control trim allows a permanent fi ne adjustment of the center channel gain, as opposed to the main
center levels set in speaker setup. These adjustments do not change the main settings. The DTS
control trim adjustment range is from 0 dB to +5dB in 1dB increments.
