The following material provides detailed instructions on how to set up the 6300, in-
cluding how to set it up to drive a Dolby Digital channel. If QUICK SETUP does not
fully address your setup needs or if you wish to customize your system beyond those
provided with QUICK SETUP, then you may need the additional information in the
sections below. However, for most users, this material is only for reference because
QUICK SETUP has enabled them to set up the 6300 correctly.
For the following adjustments, use the appropriately labeled soft button to choose
the parameter to be adjusted. To change a parameter (like an output level), it is
usually necessary to hold down the soft button while turning the knob.
1. Set the MAX LPF frequency as appropriate to your application.
[10.0 kHz] to [20.0 kHz]; 1 kHz steps
The 6300's lowpass filter is located before any dynamics processing and
affects all outputs equally. It is a phase-linear FIR filter.
The 6300's audio bandwidth can be set in three places: (1) in Setup, (2) by
remote control, and (3) in the EQ page of the Modify screen. (The latter
allows the active preset to determine the bandwidth so you can change
the bandwidth by recalling a User Preset.)
The 6300's bandwidth is always the lowest of these three settings. The
frequency in Setup is a technical parameter that determines the highest
bandwidth available. The installing engineer should set it to be congru-
ent with the sample rate of the digital system that the 6300 is driving. For
example, if the 6300 is driving a system with a 32 kHz sample rate, set the
MAX LPF to
cause excessive bandwidth and aliasing because the 6300 will automati-
cally override it with the MAX LPF setting.
