American Audio Mixer 14 MXR User Manual

							channels	CUE (1) function	is	selected.	 To	select	 a	channels	 cue	function	 press	the CUE BUTTON 
(1) that	is	directly	 associated	 with	the	specific	 channel	 you	wish	 to	monitor.	 You	may	 use	the	mixing	
function	 to	blend	 both	the	Cue	 level	 and	the	Program	 level	together.	 You	can	vary	 the	output	 level	to	
either	 hear	more	 or	less	 of	either	 of	the	 two	 levels.	Turning	the	 Cue	 Mixing	knob	to	 the	 CUE	 position	
(left)	will	allow	 you	to	hear	 more	 of	the	 Cue	 level.	Turning	the	 knob	 to	the	 PGM position	 (right)	will	
allow	you	to	hear	 more	 of	the	 Program	 level	(main	 output).	 You	may	 also	use	the	Cue	 Mixing	 Control	
to	hear	 either	 the	Cue	 level	 or	the	 Program	 level	exclusively.	 If	the	knob	is	 in	 the	 full	CUE	 position	 you	
will	only	 hear	 the	cue	 level,	 if	the	knob	is	 in	 the	 full	PGM	 position	 you	will	only	 hear	 the	main	 output.	
This	function	 is	especially	 useful	when	mixing	 without	 an	monitor.		
8. SPLIT CUE - This	 button	 will	activate	 the	“Split	Cue”	function.	 When	used	with	a	set	 of	stereo	
headphones,	 the	Split	 Cue	function	 will	assign	 the	Cue	 signal	 to	the	 left	channel	 of	the	 headphones	
and	 the	Program	 (main	output)	 signal	to	the	 right	 channel	 of	the	 headphones.	 Essentially	splitting	the	
cue	signal	 in	half.	 This	process	 will	allow	 for	headphones	 mixing.	The	CUE MIXING CONTROL (7) will 
also	work	 in	conjunction	 with	function.	 Please	note	that	this	function	 will	only	 work	 with	a	set	 of	stereo	
headphones.	
9. SHIFT (MIDI) - The button has 2 functions a soft and a hard shift. A soft shift is performed by tog-
gling the shift button, this will be indicated by a blinking shift LED. A hard shift is performed by holding 
down the shift button and combining it with another button.
NOTE: When performing a hard shift, it’s recommended you release the secondary button 
before releasing the Shift button, this is to prevent MIDI latches unless the MIDI function is a 
temporary function.
10. MASTER VOLUME LEVEL INDICATORS - The	 dual	 MASTER	 LEVEL	LED	indicators	 are	used	
to	detail	 the	master	 fader	output	 level.	The	meters	 will	detail	 the	output	 level	of	both	 the	left	and	 right	
channels.
11. FADER ASSIGN SWITCH -	This	 switch	 assigns	 a	channel	 to	the	CROSSFADER (13).	When	 a	
channel	 is	assigned	 to	the	 left	side	 of	the	CROSSFADER (13) that	 channels	 output	level	is	routed	 to	
and	controlled	 by	the	CROSSFADER (13).	Sliding	 the	CROSSFADER (21)	to	 left	 position	 will	send	the	
volume	 output	of	the	assigned	 channel to	the MASTER VOLUME LEVEL (3),	siding	 the	CROSSFADER 
(13) to	right	 position	 will	cut	that	 channels	 volume	to	MASTER VOLUME LEVEL (3). The	reverse	 is	
true	for	the	 right	 channel	 fader	assign	 switch.	 When	the	assign	 switch	is	set	 to	the	“OFF”	position	 the	
crossfader	will	have	no	function.
12.  HEADPHONE JACK - This	jack	is	used	 to	connect	 your	headphones	 to	the	 mixer	 allowing	 you	to	
monitor	 the	cue	 source.	 Use	headphones	 only	rated	 at	8	ohms	 to	32	 ohms.	 Most	DJ	headphones	 are	
rated	at	16	 ohm,	 these	 are	highly	 recommended.	 Always	be	sure	 the	CUE LEVEL VOLUME (6) is set to 
minimum	before	you	put	the	headphones	on.
13.  FEATHER FADER PLUS CROSSFADER - This	fader	 is	used	 to	blend	 the	output	 signals	 of	chan-
nels	 one	and	 two	together.	 When	the	fader	 is	in	 the	 full	left	 position	 (channel	 1),	the	 output	 signal	of	
channel	 one	will	be	controlled	 by	the	 master	 volume	 level.	The	same	 fundamentals	 will	apply	 for	chan-
nel	 two.	 Sliding	 the	fader	 from	one	position	 to	another	 will	vary	 the	output	 signals	 of	channels	 one	
and	two	respectively.	 When	the	crossfader	 is	set	 in	the	 center	 position,	 the	output	 signals	 of	both	 the	
channels	one	and	channels	two	will	be	even.
14.  CROSSFADER CURVE ADJUSTMENT - This	rotary	 knob	is	used	 to	change	 the	way	 the	cross-
fader	 will	operate.	 The	crossfader	 can	operate	 in	different	 modes,	“NORMAL	 CURVE”,	“QUICK	CURVE”	
or	any	variation	of	the	two.	(Quick	Curve	is	usually	used	for	scratching).

28.  MAIN POWER SWITCH - This	is	the	 main	 power	 ON/OFF	 button.	Before	main	power	 is	
applied,	 be	sure	 you	have	 made	 all	connections	 to	the	 mixer.	 Also	be	sure	 your	 amplifier(s)	 is(are)	
tuned	off.	Remember	 to	avoid	 damaging	 pops	to	the	 speakers,	 the	mixer	 is	turned	 on	first	 and	
turned	 off	last.	
29. AC CONNECTION - This	 connector	 is	used	 to	supply	 main	power	 to	the	 unit	 via	the	 included 	
detachable	 power	cord.	The	power	 connection	 uses	an	I.E.C.	 type	connector,	 use	only	 the	supplied, 	
polarized	 AC	power	 cord.	Use	only	 a	power	 cord	that	matches	 this	type	 of	connection.	 Be	sure	 to	
only	connect	this	 unit	to	a	power	 outlet	that	matches	 the	printed	power	 label	on	the	 unit.	Never	 use	
a	power	 cord	when	 the	ground	 prong	has	been	 removed	 or	broken	 off.	The	 ground	 prong	is	used	 to	
reduce	 the	risk	 of	electrical	 shock	in	case	 of	an	 electrical	 short.	This	cord	 is	designed	 to	fit	in	one 	
direction	 only.	Do	not	 attempt	 to	force	 a	cord	 if	it	 does	 not	fit,	be	 sure	 the	cord	 is	being	 inserted 	
properly.
     FUSE HOLDER – This	housing	 stores	the	10	amp	 GMA	 protective	 fuse.	Always	 replace	 with	the	
exact	 same	type	fuse,	 unless	 otherwise	 instructed,	 by	an	authorized	 American	Audio®	service	 tech-
nician.	Replacing	 with	any	other	 type	of	fuse	 than	 that	of	the	 recommended	 fuse	will	void	 your	 unit	
warranty.

Due	to	fog	 residue,	 smoke,	and	dust,	 cleaning	 the	mixer	 should	 be	carried	 out	periodically	 to	residue	
build	 up.		
1.			Use	 normal	 glass	cleaner	 and	a	soft	 cloth	 to	wipe	 down	 the	outside	 casing.
2.			Use	 a	cleaner	 specially	 designed	 for	electronics	 to	spray	 in	and	 around	 the	knobs	 and	switch.	 	 	
This	will	reduce	 small	particle	 built	up	that	 can	effect	 the	proper	 operation	 of	the	 mixer.	
3.			Cleaning	 should	be	carried	 out	every	 30-60	 days	to	prevent	 heavy	built	up.
4.	 Always	 be	sure	 to	dry	 all	parts	 completely	 before	plugging	 the	mixer	 in.
Cleaning	 frequency	 depends	on	the	 environment	 in	which	 the	mixer	 operates	 (i.e.	smoke,	 fog	residue,	
dust,	 dew).
The	crossfader	is	“Hot	Swapable”	which	means	it	may	be	replaced	at	any	time,	even	when	power	is	
applied.	Only	replace	with	American	Audio	Part	Feather	Fader	Plus.	Replacing	with	any	other	model	
fader	may	seriously	damage	your	mixer.
Replacing	the	Crossfader:
1.		 Disconnect	the	mixers	main	power	supply
2.		 Using	a	number	two	Phillips	screw	driver,	unscrew	the	each	of	the	stainless	steel	retain	screws		 	
that	hold	the	crossfader	in	place.
3.		 Gently	remove	the	crossfader	from	its	seated	position.	You	may	need	to	wiggle	the	crossfader		 	
slightly	to	remove	it.
4.		 After	removing	the	crossfader,	disconnect	the	ribbon	cable	that	attaches	the	crossfader	to	the		 	
PC	board.	Grasp	the	crossfader	by	its	base	and	pull	the	ribbon	cable	by	its	connector	not	the			
actual	cables.	The	connector	is	designed	to	only	fit	one	way,	so	don’t	worry	about	the	connec		
tors orientation.
5.		 Connect	the	new	crossfader	to	the	ribbon	cable	and	replace	in	reverse	order.
