“Level” has thirty-three choices: from +16 dB to +00 dB to -16 dB, in 1 dB steps. The purpose of “Level” is to make it 
possible for you to set up each Source (

AV1

 through 

AUD3

) so that as you select each one the output level of each is 

roughly the same as the others. Thus if you have a CD player with a very high output and a VCR with a low output 
level you can turn down (in -1 dB steps) the “Level” of the CD player input and/or turn up (in +1 dB steps) the “Level” of 
the VCR input. It is very unlikely you will need to increase or decrease the level by anywhere close to the +/-16 dB 
range. The "Level" setup affects the master volume for that particular source in all modes. For example, if you have a 
CD player on input "

AUD1

" and a DVD player on input "

AV1

", you might want to lower the “

AUD1

” volume by adjusting 

its “Level” a few decibels lower to better match the two sources with different dynamic range. (CD's, at least with 
‘popular’ music, usually have less dynamic range than a movie). So it's a master volume offset for the sources. 
 
Since setting these levels will require you to actually listen to each active input, we suggest you finish setting the 
“Mode” and “Input” parameters for all of the inputs you will be using before beginning this phase of the setup. It may 
take a few minutes to figure out how to get from the “Level” setup of 

AV1

 to the “Level” setup of 

AV2

, but it only takes 

a few button pushes. 
 
Turn on each source that is plugged into the 

SSP-25

 and play it. Put a tape into the VCR, turn on the satellite, get a 

DVD disc playing on the player and/or get the laser player playing, turn on the Tuner. Turn down the Master Level of 
the 

SSP-25

, so it won’t play too loud, and then switch from input to input while listening to the different sound pressure 

levels from each. On a pad of paper make a few notes about which source needs a boost and which needs to be 
reduced in level.  
 
Once you’ve determined which are too loud and which are too soft you can begin to reduce or increase their levels. 
You can change the output levels for a source using the ”

/\

” key (above the “

ENTER

” key), and the “

\/

” key (below the 

ENTER

” key). Do not attempt to change to setting of “Level” with the Master Volume control on the processor or on 

the wand. You will not make a change to the “Level” if you do, though the volume my go up or down. Leave each 
source playing while setting the levels. Since the processor will continue to play even while you’re setting it up, you can 
change the “Level” setting and hear the difference you’re making. This may take a little while, and a little 
experimentation, but when you’re done there won’t be any real surprises as you switch from one input to another. 
 
Begin the setup procedure by deciding which source you want to change the level of (first), and then select it by 
pressing its direct access key on the remote. All the sources should be playing.  
 
Next, if you are starting from the display that appears when you first turn on the 

SSP-25

, you press “MENU”, then the  

>

” key to reach “Source Setup”, then “

ENTER

” to select “Source setup.” “

AV1

 setup” will appear and you can select 

this input by pressing the “

ENTER

” key once again, or you can move to the other inputs by pressing the  “

>

” key or the 

<

” key. When you have reached the input you want press “

ENTER

.” “Mode” and its setting will appear, so press the 

>

” key twice to move to “Input” and then to “Level.” Press the “

/\

” key to increase the level and the “

\/

” key to reduce 

the level. When you hear a level you think might be more satisfactory for the input you can listen to all the inputs by 
just pressing the source keys on the remote (or by using the selection keys on the front panel). You will continue to be 
in setup, and the source you are setting up does not change. Only the source you are listening to will change. (When 
you select each source the display changes to identify the new source, then briefly displays the input type and the 
decoding type, and then reverts to the setup display. Even though the source you’re listening to changes the source 
you are setting up does not. If the source you’re setting the “Level” on is too loud or too soft select it with its direct 
access key and use the  “

/\

” or “

\/

” key to change its level again. When you think you’re done press the “MENU key to 

leave the source setup mode. You will be back at the “Source setup” display, with the input you selected in the lower 
line. 
 
If there is another input you wish to change the “Level” setting of press the “

>

” or the “

<

” key until you see it in ht e 

display. Select it as before by pressing the “

ENTER

” key, press the “

>

” key twice to reach “Level” and then use the “

/\

” 

or ‘

\/

” key to increase or decrease the output level of the new source. Repeat the listening test as above. If necessary, 

continue selecting the different inputs and setting their levels until you’re satisfied all the inputs are pretty well 
matched. Press the “MENU” key two or three times until you have reached the main display.
