REFERENCE INFORMATION
The following information is provided for reference only. Please consult a
professional if unsure about any aspects of commercial or residential
installations.
Speaker Connection
The rear panel of the amplifier contains 2 Line Outputs (Line 1 and Line 2).
BE SURE TO CONNECT SPEAKERS PROPERLY, see line voltage instructions below. The
speaker lines are to be connected directly between the appropriate COM
terminal on the terminal strip and the terminal corresponding to the impedance
of the speaker(s). Connect the cables to the terminals on the screw terminal
strip provided. Use the screw terminals which correspond to the proper
polarity of the speaker(s). One lead must always be connected to the COM.
IMPORTANT NOTICE: When 70V constant line voltages are used, a line
matching transformer must be used with each speaker. All transformers must be
connected in parallel.
ALWAYS CONNECT LINE TRANSFORMERS IN PARALLEL, NEVER CONNECT IN SERIES
Speaker Impedances Speaker terminal taps for 70V constant line voltage are
provided on the rear panel of the unit. To connect the power output directly
to a speaker or PA horn or a combination of speakers and/or PA horns, connect
to the COM and (+) terminal on the strip. Be sure the speaker(s) or PA horn(s)
can handle a reasonable power output from the amplifier or permanent damage to
the speaker(s) or PA horn(s) may result. Also, be careful not to overload the
amplifier with too many speakers or PA horns. If it is desired to use a number
and variety of speakers, the speakers must be arranged in various series or
parallel arrays to provide proper impedance matching. 70V constant line
voltage must be used (parallel connection only). If you are not familiar with
impedance matching, consult a professional installer or technician for advice.
If 70V constant line voltages are used, a line matching transformer must be
used with each speaker. Again do not overload or use incompatible speakers.
Line transformers are the preferred method for multi-speaker installation.
Cable Requirements
Output cabling need not be shielded in most cases and should be of sufficient
gauge to minimize losses due to the resistance of the wire over long runs
(insertion loss). Cable thinner than 18 gauge AWG is not recommended. Long
runs require 16 gauge AWG or heavier.
In some cases where the output cable is run in close proximity to unshielded
intercom cables, electrical cables, radio transmission antennas, or other
sources of interference, or when the amplifier is being used for paging from a
telephone system, the amplifier may require shielded output cabling to prevent
audio feedback or interference.
WHENEVER IN DOUBT ABOUT INSTALLATION, CONSULT WITH A PROFESSIONAL INSTALLER OR
TECHNICIAN. OTHERWISE, PERSONAL INJURY, OR DAMAGE TO THIS AMPLIFIER AND/OR
SPEAKERS MAY RESULT AND YOUR WARRANTY MAY BE VOID.
FEATURES AND FUNCTION
Rack Mounting
The XPA-300/500 both come with Rack Mounts in the box.
Remove the two chassis screws from each side panel, closest to the front panel
Attach the rack-mount ears to the sides of the front face plate using the
screws that come with the rack mounts (2 each side).
The amplifier will occupy 1U of rack space.
Ensure that the unit is in a well-ventilated area that provides adequate
cooling. Free air space is required above the amplifier and below the
amplifier. The recommended distance is 1U to 2U, 1.75″ to 3.5″ being sure to
avoid blocking any vents on the unit’s chassis.
Bottom feet on the amplifier chassis may be removed if
necessary.
NOTE: Do not place the screws back into the chassis. Without the feet,
the length of the screw may touch internal components and affect the
performance of the amplifier.
Balanced Input
Use the BALANCED INPUT to connect balanced or unbalanced cables to the
amplifier.
NOTE: The unbalanced connection needs a jumper from the Shield to
the Negative. The unbalanced connection is used when there is no balanced
source and more additional connections to the amp are needed.
Unbalanced Connections
Use standard RCA cables to connect sources using the UNBALANCED LINE IN input.
Connect sources through the applicable mono input. Use the LOOP OUT ports to
connect more amplifiers or equipment.
Using Fixed
Loop Out The LOOP OUT connections on the amplifier may be used to send audio
signals to other equipment, or to the other channel of the amplifier. This
connection sends audio signals out from the UNBALANCED INPUT of the channel.
