Hafler XL-600 Owner's Manual - Output Connections
Output Connections
To preserve the high damping factor of the XL-600, and to
minimize power loss, the use of at least
16 gauge speaker
wire is recommended, especially for speakers of less than
8 ohms impedance, or for wire runs of 15 feet or more.
Your dealer can advise you on the wide variety of premium
cables available from specialty manufacturers. The gold
plated output binding posts on the XL-600 are of the
“5-way” type, and will accept
single
or
dual banana plugs
,
spade plugs
,
pin plugs
, or bare wire through the hole in the
center post. If using bare wire connections, tinning the end
of the wire with solder is recommended, to avoid any frayed
ends of the wire shorting to adjacent terminals or the
chassis.
Be sure to follow proper phasing relationships when con-
necting the speakers, FOR STEREO OPERATION, the
amplifier “+”, or RED terminal, must be connected to the
speaker’s “+”, or RED terminal, and the amplifier’s “--“, or
BLACK terminal must be connected to the speakers “--"
or BLACK terminal. Speaker cables identify one conductor
from the other by the wire color, or by marking or coloring
the insulation, FOR MONO OPERATION, see the follow-
ing section.
Monophonic Operation
To drive a single speaker with increased power capability,
the XL-600 can be operated in a “bridged” mono configura-
tion, to deliver over 900 watts into 8 ohms. To use this
mode, set the stereo/mono switch to MONO, connect the
input signal to the LEFT INPUT ONLY, and connect the
speaker load to the two RED BINDING POSTS ONLY.
These output terminals are “floating”, with the right red
terminal the "-” connection, and the left red terminal the
“+” connection. In this mode, THERE ARE NO CONNEC-
TIONS TO EITHER BLACK BINDING POST OR RIGHT
INPUT JACK. Make all changes with the power off. It is
recommended to place a piece of tape over the unused
connections to avoid later confusion.
