Delayed Turn On’s.

When the power conditioner is turned on, the two outlets labelled “Delay Min” turn on immediately (along with the unswitched outlets already turned on).

About two seconds later the next two outlets labelled “Delay Med” turn on.

About two seconds later (four seconds from when the power conditioner was first turned on) the last two outlets labelled “Delay Max” turn on.

Typically ancillary equipment such as equalizers, processors, DVDs etc. are connected to the outlets labelled Delay Min and Delay Med.

Typically larger power amplifiers are connected to the outlets labelled “Delay Max” so that other equipment has time to stabilize before the amplifier gets power, seriously reducing loudspeaker clicks and pops. If multiple amplifiers are too powerful to connect to a single Knoll power conditioner, we suggest using a 12V DC wall wart power supply connected to the Delay Max outlet on the power conditioner and connect the wall wart to the amplifier trigger input(s). The amps are plugged into the wall and not to the power conditioner.

If there is two larger amplifiers to be connected to this power conditioner, we suggest that one be connected to the outlets labelled Delay Med and the other to the outlets labelled Delay Max.

If a longer eight-second turn on sequence instead of the standard four second start up sequence is required, your authorized Knoll dealer can remove an internal shunt to accomplish this.

Power Down

When the power down command is received by the Knoll Power Conditioner a reverse sequence to the power up is initiated. Immediately when the power down command is received, the outlets labelled “Delay Max” are shut off. Two seconds later, the outlets labelled “Delay Med” are shut off. Two seconds later, the outlets labelled “Delay Min” are shut off. The last two outlets labelled “Unswitched” are never shut off.

Rear Panel Trigger

The Knoll Power conditioner is equipped with a remote trigger activation to turn the power conditioner off and on (just like the front switch). When a 3-24 VDC or VAC constant signal (trigger) is present, the power conditioner will power up in sequence and stay on as long as the signal is present. When the trigger signal is lost, the power conditioner begins its power down sequence and stays off until either a trigger signal is reacquired or the front panel power button is pressed. When connecting to the trigger, polarity is unimportant.
