Power Switch This toggle switch has two "ON"
positions that reverse the AC power line polarity.
Choose the ON position with least hum.
Low Impedance Channel Inputs These low-
impedance XLR connectors accept inputs such as
professional low-impedance microphones and
electronic musical instruments having low impedance
outputs, The XLR inputs are unbalanced," but may
be converted to balanced (floating) inputs by the
addition of easy-to-install optional "Balancing
Transformer Modules" (not available for the
EM-10011). :
High Impedance Channel Inputs These TS (tip-sleeve)
phone jacks are designed for high or medium
impedance microphones, low-level instruments
(like electric guitars or instruments with pick-ups),
or high level instruments (such as keyboards).
. AC Power Cord This 3-wire cord is for connection
to any 110-120 V AC, 50 or 60 Hz grounded outlet.
*NOTE: The terms balanced and unbalanced, as used in this
manual, have nothing to do with stereo perspective or signal
level. Balanced refers to a 2-conductor shielded cable in which
neither signal-carrying wire is grounded.
'
Fuse Holders Always replace the fuses with the same
| size and type (AGC or equivalent).
. Speaker Output Jacks These standard phone jacks are
Left and Right speaker-level outputs from the built-
in stereo power amplifier. There are two paralleled
Jacks per channel; this internal "Y" adapter is pro-
vided as a convenience to power two separate sets of
speakers simultaneously. (Refer to page 11).
Normally, the Program mixing buses feed the
speaker outputs, and both jacks from each power
amp channel are simultaneously controlled by the
corresponding Master Program faders. The Power
Amp In jacks do permit other signal sources to feed
the speaker outputs (in lieu of the stereo program
mix), such as the monitor mix buses or even an
external mixer or keyboard.
. Power Amp Inputs These jacks permit the con-
nection of any line-level low: or high impedance
signal directly to the mixer's power amplifier,
replacing the internal signal flow from the stereo pro-
gram mix. The jacks are useful for inserting a com-
pressor/limiter ahead of the power amp.
