SA-REFERENCE FEATURES

ERROR DETECTION

The Plinius SA-Reference Power Amplifier has in-built error detection. This will function under the following conditions:

When the amplifier is overdriven/clipped

If any internal fuse is damaged

Should either of these circumstances arise the amplifier will disconnect both channels and mute the input. This condition will remain until the input signal level is reduced or the damaged fuse replaced. When error detection is triggered the power LED will turn off and the mute LED will pulse. The internal error LED (located towards the front of the circuit board in the top cavity of the amplifier) will also light.

FUSE PROTECTION

When any internal fuse is damaged one or more fuse warning LEDs will light. These LEDs are under the amplifier lid located to the centre front of the main circuit board. Should any of the internal fuses need to be replaced the base of the amplifier will need to be removed and the fuses located. The rail fuses are near the middle of the circuit board. Replace them with the same type (10 amp normal blow).

IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING.

Please note that fuse failure may indicate a severe problem. Check all speakers and speaker cables for damage/short circuit etc. Should the amplifier continue to exhibit rail fuse failure contact your PLINIUS dealer.

ECOLOGIC CONTROL

The Plinius SA-Reference is also fitted with a microprocessor which monitors and performs the Bias and Mute functions. It is programmed to switch the amplifier back into Class AB if no signal has been present at the input for a predetermined time. This time can be adjusted to Off, 15, 30 or 60 minutes. During the last minute without signal the bias LED will pulse to indicate the unit is about to return to Class AB. The purpose of this function is to prevent the amplifier being left in Class A while unattended for a long period of time.

To adjust this time constant the amplifier lid must be removed and the small jumper JP4 located on the main circuit board at the front left shifted to the appropriately labelled pins. Please ensure that your amplifier is switched OFF and disconnected from the mains supply before this adjustment is made. The factory setting is 30 minutes.
