corresponding on/off button(s) on the speaker selector.
Refer to the protection chart for the correct setting of the
Protection button.
Constant Protection Switch
The HPS-4/HPS-6 is equipped with a manual override for the
protection circuit that enables you to defeat the front panel
protection switch and maintain constant impedance protec-
tion. This will safeguard your amplifier from being overdriven
due to accidental or improper use by anyone unfamiliar with
the equipment.
To engage this override, move the rear panel “Constant
Protection” switch to the “On” position. Constant imped-
ance protection will be maintained until the switch is turned
to “Off”.
