M-Audio SBX user manual Rear Panel Features

1.	Power Mode LED: This LED indicates the power status. If the			-muting
Rear Panel Features:
	circuitry is engaged, this LED will be amber if there is no audio signalautothe SBX,
	and green when the SBX receives a signal. If “Auto-Power” is switched off, then
2.	this LED will remain green.
	“Level” control knob: This knob controls the amplifier level of the SBX. The gain
	range is from minimum to maximum, labeled “Min” and “Max,” with Min being
3.	full attenuation and Max being full volume.
	Phase control knob: This knob controls phase of the crossover frequencies of
4.	the Subwoofer and the Satellites from 0 to 180 degrees.
	“Subwoofer” LPF control knob: This knob de ignates the cutoff frequency of the
	SBX using LPF, or low-pass filter. This		setting will determine	the highest
5.	frequency that the SBX will reproduce.
	“Satellites” HPF control knob: This knob determines the HPF, or high-pass filter
	cutoff frequency for the Satellite speakers while using the SBX’s Stereo Bass
	Management System. The Satellites control knob is functional only when the
6.	HPF Bypass switch is set to Off.
	Input section: This section provides two balanced XLR inputs and two 1/4” TRS
	connectors that may be	for balanced (TRS) or unbalanced (TS) operation.
	Either XLR or TRS may be used as your audio input. These inputs are designated
	as “L” and “R” for operation in bass management mode. When bass
	management is not used, either the L or R input may be used to input signal to
7.	the SBX.
	Auto Power On/Off Switch: When this switch is set to “On,” Auto Power mode is
8.	engaged. Switching to “Off” will defeat Auto Power mode.
	HPF Bypass switch: Switching HPF Bypass to “On” will bypass the Satellites HPF
	control knob, effectively defeating the SBX’s Stereo Bass Management System.
	With HPF Bypass switched off, the “Satellites” HPF cutoff frequency control knob
9.	is engaged and bass management is operational.
	Output section: This section provides three balanced XLR outputs labeled “Extra
	Sub” and “L” & “R.” The Extra Sub output gives you throughput directly from the
	inputs for the purpose of connecting an additional subwoofer. The L and R
	outputs are to be used for connecting Satellite speakers (your left and right
0.	mains) when using the Bass		System.
	Power cable socket: This socketManagementaccepts standard grounded AC cable.
11. Fuse holder: This fuse holder allows the replacement of a fuse for the purpose
12.	of circuit protection.
	Power On/Off switch: Switching to “O ” will power the SBX subwoofer.
13.	Switching to “Off” will power the unit down.
	Manufacturer’s Label: This section gives the model number and manufacturer
	information, including important power requirement information. See section,
14.	“Correct Power Operation.”
	Voltage-Select Switch: Provides 2 selections - 115VAC (120VAC) and 230VAC,
	and should be set to match the “house current” (receptacle) voltage of the
	country/location in which the speaker is used. The 115V (120V) setting is correct
	for the USA and the 230V setting correct for most of the UK and Europe.
