Sonic Impact Technologies Power 2 manual Warning: Amplifier Output Is Balanced

	Damage due to bypassing the fuse or due to replacement of a fuse of higher ratings will
	not be covered under the warranty. To access the fuse, insert the slotted screwdriver,
	pushing to compress the internal spring and turn counterclockwise to unlock the housing.
	The spring will then eject the fuse and the housing.
I Left and Right Channel	These switches must both be rotated to the desired position to select the desired input,
Input Selector Switches	XLR Balanced, RCA Single-Ended Non-Inverting (+) or Inverting (-) for normal operation.
	In the MUTE position, this control allows for BIASING CONTROL of the power tubes and
	for safe cable swapping without shutting down the amplifier. When both switches are in
	the M U T E position the front panel Power LED will turn R E D. Note: This position is purpose-
	ly positioned at 12 o’clock so it can be easily determined when access is obscured. The
	f ront panel Power LED will also turn red if this switch has selected an input which has no
	connection. If any input selector switch is in MUTE and the other is not, the Power LED will
	be a Red & Green colour at the same time.
J Left and Right Channel	These inputs accept an XLR balanced connection from the preamp’s left and right
Balanced XLR Inputs	balanced outputs.Connections should be made left channel to left channel right channel
	to right. Note: The XLR pin configurations are as follows:
	Pin#1- Ground

Pin#2- Positive
Pin#3- Negative	View from front of connector.

K Left and Right Channel	These inputs accept an input signal from a single-ended output of a preamp or source
Single-Ended RCA	that is 180°out of phase relative to the original signal and correction for this configura-
Inverting Inputs	tion is desired. The input on the Power 2 does invert the phase of the output signal, rela-
	tive to the input signal. Connections should be made left channel to left channel right
	channel to right.
L Left and Right Channel	These inputs accept an input signal from a single-ended output of a preamp or source
Single-Ended RCA	that is in ....absolute phase or are used if it is desired to maintain the phase of the signal
Non-Inverting Inputs	from the preamp. Simply explained, this input does not invert the phase of the output sig-
	nal relative to its input. Connections should be made left channel to left channel right
	channel to right.
M Left and Right Channel	This post is offered for use when a ground connection is required (i.e. when amplifier’s
Ground Posts	function is being tested by a technician). It has no use for day-to-day audio related
	operation.
N Left and Right Channel	These posts are used to connect the amplifiers to the speakers; positive terminal to posi-
Loudspeaker Binding Posts	tive terminal, negative terminal to negative terminal, from the right posts to the right
	speaker and left posts to the left speaker.
	WARNING: AMPLIFIER OUTPUT IS BALANCED.
	CARE MUST BE TAKEN TO ENSURE THE AMPLIFIER IS NOT CONNECTED
	TO LOUDSPEAKERS (CERTAIN SUBWOOFERS) OR LOUDSPEAKER SWITCH-
	BOXES THAT HAVE A COMMON GROUND. CONSULT YOUR DEALER OR
	SONIC FRONTIERS DIRECTLY FOR FURTHER CLARIFICATION REGARDING
	CONNECTIONS TO ITEMS IN THESE UNIQUE CASES. DAMAGE TO THE
	AMPLIFIER OR CONNECTED EQUIPMENT WILL NOT BE COVERED UNDER
	WARRANTY IF THESE WARNINGS ARE IGNORED.
