PHONES and CD/TAPE MP3 IN Section
42. PHONES Control knob - This control adjusts the level of Headphone Output.
43. MAIN MIX 2 Control Knob - The mixer provides a second set of output connec-
tors carrying a duplicate of the MAIN MIX signal for the purpose of feeding
another speaker zone or recorder. The MAIN MIX 2 control knob is used to set
the volume of the MAIN Mix 2 output.
44. Mute CH 1-12 Switch - This switch mutes input channels 1-12. This is espe-
cially convenient when you take a break and want to leave all the levels set so
they are ready when you begin to use your PA system again. The MUTE switch
features an electronic circuit for silent switching that ramps the signal up and
down to prevent pops when the switch is turned on and off.
45. PFL Switch - The CD/TAPE MP3 input channel’s PFL, or Pre Fader Listen
switch allows you to listen, or “solo” the CD/TAPE MP3 input in the head-
phones. When the CD/TAPE MP3 input channel’s PFL switch is pressed
down, that channel’s signal is assigned to the solo bus and can be heard in
any optional headphones plugged in to the PHONES connector located in
the front panel jack field. Since the signal is sent pre fader, you can hear the
signal regardless of the position of the channel Level control. This allows you
to listen to a channel by itself to cue up a song on a CD player without having
to play it through the main PA speakers.
46. CD/TAPE MP3 Fader - The S4000 has a dedicated line level
CD/TAPE MP3 input to connect a CD, Tape or MP3 player.
The CD/TAPE MP3 level fader control is used to adjust the
volume of the signal connected to the CD/TAPE MP3 input.
MONO/SUBWOOFER Output Section
The S4000 has a MONO output that can be used to send to a secondary speaker
zone. You can also configure the MONO Output to drive a subwoofer system by
using the built-in variable Low Pass Filter.
47. FREQUENCY Control Knob - Use the FREQUENCY control to adjust the cross-
over point for the Low Pass Filter in a range of 20 Hz to 200 Hz when the
MONO/SUB OUT is connected to a subwoofer. The FREQUENCY control
knob is active when the SUBWOOFER ON/OFF switch is set to ON.
48. SUBWOOFER ON/OFF Switch - Used to engage the Low Pass Filter and turn the
MONO output into a subwoofer output.
49. AFL (After Fader Listen) Switch - The MONO output’s AFL, or After Fader
Listen, switch allows you to listen, or “solo” the MONO in the headphones.
When the MONO AFL switch is pressed down, the left/right mix will be
heard in any optional headphones plugged in to the PHONES connector
located in the front panel jack field. Since the signal is sent after the MONO
level fader, you hear the signal with the added gain from the MONO Level
control
50. MONO Level fader - The MONO level fader control is used to adjust the vol-
ume of the signal connected to the MONO/SUB output.
