The permissible settings are shown in Figure 11, and the effects of
each on system gain and headroom is described in Table 2. Note that
combinations of header settings other than those shown should not be
used as they do not give a proper balanced drive.

Setting Output clip System gain Description
Level /dB (Note 1)
3dBm +3dBm 0 Mic level output. Factory default
13dBm +13dBm +10 MSR-604 pre Mk II compatibility
23dBu +23dBu +20 Line level output
(Note 1. Gain between input XLR and output XLR with channel Gain switch set to 0dB
and input pad set to MIC).
NOTE: The output levels are referred to using both dBm and dBu for
different settings. This is because the unit is capable of driving 3dBm or
13dBm into a 600
Ω
load but the 23dBu output, although capable of
driving 600
Ω
will, drop slightly in level for loads below 2k
Ω
.
