6.4.2 ADJUSTING INPUT SENSITIVITY
Press the > to reach the next setup screen.
6.4.3 INPUT LEVEL SETUP
Here you can set up the individual Analog inputs.
This setup makes it possible to ensure that as you
switch from one input to another the output sound
pressure levels (SPL) remain the same. There are
two easy ways to set up analog inputs. The first is
to press the ENTER key to reveal the next screen.
6.4.4 METER SETUP
If you have a dynamic analog audio source (like a
CD) playing into this input you can hear the SPL
increase or decrease as you press the /\ and \/ key
on the remote. Using your ear (or an SPL meter)
and the on-screen meter you can set a level for all
the analog inputs. The range is +/- 16 dB, but it is
quite likely that only a small change, if any, would
be needed. Pressing the /\ or \/ key increases or
decreases the analog input sensitivity only. Increase
or decrease the sensitivity when the output level
from this input does not match the output levels
from other analog inputs.
6.4.5 AUTO CALIBRATION OF INPUT
The second easy method of setting up the
individual analog inputs is to let the SSP-75 do all
the work. You can press the A.CAL button at either
the initial Analog Setup screen, or at the meter
setup screen above which appeared after pressing
the ENTER key. Be sure the supplied microphone is
plugged into the MIC jack on the rear of the SSP-
75. (the microphone should have a fresh battery
and its switch should be ON). Place the microphone
at the preferred listening position, preferably at ear
level. Holding the microphone may make more
noise than you realize and throw off its accuracy.
6.4.5.1 A.CAL ADVISE
Before you press the A.CAL button you must
have a dynamic CD, or other source (Tuner, SACD,
Karaoke), playing through the current input.
Press the A.CAL button on the remote. The
screen immediately changes to red and the
following appears:
When you press the A.CAL button to begin the
auto-calibration process the SSP-75 will listen
through the microphone to the level of the output
and gradually raise or lower the level until the
resultant SPL matches a nominal level, then
automatically revert to the previous screen.
Once you have finished with the setup of the
various inputs you will be using you can press the
MENU key again to reach the next setup level:
6.5 SPEAKER SETUP
6.5.1 SPEAKER SETUP DISCUSSION
The second press of the MENU key brings you to
an easy but important part of the setup process.
To help you get the most out of your theater
experience the SSP-75 needs to know how
many speakers your system has and what kind of
speakers they are. In the following section we will
show you how to set up the speakers. You should
read over the following paragraphs before you
decide how you will describe your speakers. How
you define the size and number of speakers has a
direct effect upon how the system will sound when
playing movies and stereo.
Although the default for the main speakers (Left
and Right Front) is set to ‘Small/THX’, you should
carefully decide what you want to accomplish, and
do some experimental listening. When the Front
Left and Right and Center (if one is present) are
set to ‘large’, no information except LFE (Low
Frequency Effects, the .1 of the 5.1 specification)
is directed the Sub-woofer. Many movies have low
frequency information but little or no LFE. Basically,
the Sub-woofer will only get signal during a big
effect, perhaps during an explosion. If you expect
more low frequency information, and a lot of
people do, you may not want to set the front
speakers to ‘large’. When you define the front
speakers as ‘Small/THX’, all Bass information below
80Hz is sent to the sub-woofer, including any LFE.
One setup method, and a method many installers
favour, is to send all information for the Front Left
and Front Right speakers to either one or two sub-
woofers, and from there utilize the cross-over in the
sub-woofer(s) to send the higher frequencies to the
Left and Right Front speakers.
Define Setup that there is no Sub-woofer, and
that the Left Front and Right Front speakers are
‘Large’,and the center speaker is ‘Small’. (Although
there is a Sub-woofer, there is not
one attached to the Sub-woofer output, unless
of course you put one on that output just to
reproduce the LFE signal). This method will direct
all low frequencies and the LFE information to the
‘Large’ speakers, and will also allow the Center
speaker to have the most dynamic range.
All in all, though, the best setup is the one which
sounds best to you.
