Grace M905 - Speaker Output Level and Balance Settings

21
If the setup mode is changed or exited prior to selecting the “<”, any modications to the name will be
ignored.
LEVEL OFFSET  The volume level of each speaker system can be matched by adjusting the level oset on
each speaker output. When a speaker output is selected, this oset is added to the speaker and sub (if
applicable) output levels.
The level oset range is +/- 20dB in 0.5dB steps.
BALANCE  The balance of each speaker output can be independently adjusted. The available balance
range is -10dB to the left or right in 0.5dB steps. When no balance adjustment is present on the speaker
output, the parameter displays “center”.
SUB OUTPUT  The sub output can be congured for each speaker output. Available options are disabled,
L+R Stereo, L+R Mono, Mono->L and Mono->R. NOTE: For the sub output to be active, the SUB/DAC/
METER output must be congured for sub output mode (see SUB/DAC/METER setup section below). The
function of each of these settings is as follows:
• disabled – the sub output is turned off when this spearker system is selected
• L+R Stereo – the sub output is on for this speaker system and functions as a stereo output
• L+R Mono – the sub output is on for this speaker system and is summed mono on both output connec-
tors
• Mono ->L – the left sub output is on for this speaker system and is the mono signal
• Mono ->R – the right sub output is on for this speaker system and is the mono signal
SUB OFFSET  The sub output can have a programmed level oset to match each speaker system. When a
speaker output is selected, this oset is added to the sub output level when the sub output is enabled.
The sub oset range is +/- 20dB in 0.5dB steps.
PRESET LEVEL GLOBAL  This parameter sets the speaker output preset level. This parameter is the same
for all speaker outputs. Available range corresponds to the standard level display and is 0-100 in 0.5dB
steps.
PWR UP LEVEL GLOBAL  This parameter sets the speaker output level that is set when the system is pow-
ered on. Available range is 0-100 in 0.5dB steps. This parameter is the same for all speaker outputs. The
default is 0.0.
DISPLAY MODE GLOBAL  This parameter sets the speaker output display mode. When standard level is
selected, the speaker level is displayed as a 0-100 range in 0.5dB steps. When reference level is selected,
the speaker level is displayed as a 100dB range in 0.5dB steps based on the ref. level setting (see below).
This parameter is the same for all speaker outputs.
REFERENCE LEVEL GLOBAL  This parameter represents the reference level that is displayed (when display
mode = reference level) at the current volume setting. Available range is the current volume setting +/-
100 in 0.5 steps. This parameter is the same for all speaker outputs.
The following is an example of how the reference level may be congured for an 82dBSPL reference
listening level:
• Play and monitor a nominal level noise source.
• Adjust the speaker level until the SPL measurement at the listening position equals 82dBSPL.
• Enter SETUP and navigate to the REF. LEVEL (GLOBAL) parameter and adjust it to 82.
