Bogen & X600 manual Sleep Switch, Power Sequencing Switch, Power Status Indicator, Operation

Operation

Sleep Switch

The Black Max amplifier includes a sleep mode feature that greatly reduces the power consumption of the amplifier after it has been idle (no audio activity) for more than 3 minutes. Any audio activity present at the input will power up the amplifier instantaneously and noiselessly, so that there is no loss of audio. The Sleep Switch is located on the rear of the unit. The sleep feature is activated by setting the switch to the AUTO position. Setting the switch to the OFF position will inhibit the amplifier from ever entering sleep mode.

Power Sequencing Switch

The setting of the Power Sequencing Switch on the rear of the Black Max amplifier determines how the amplifier will power up. When the switch is set to the OFF position, the amplifier will power up and down convention- ally when the front Power Switch is turned ON and OFF.

To use the sequencing feature built into the amplifier, the Power Sequencing Switch must be placed in the ON position on a slave amplifier. The slave amplifier will now power up when it receives the proper trigger through the terminal strip wiring (see section Sequential Turn-On Wiring for proper wiring of the power sequencing terminal strip).With the Power Sequencing Switch in the ON position, placing the front Power Switch in the ON position will not result in the amplifier turning on. It will instead remain in a standby state until triggered through the sequencing feature.

Power Status Indicator

A Power Status Indicator is provided on the rear of the amplifier.The Black Max amplifier has different states of powering up, depending on whether power sequencing is used or not.The Power Status Indicator provides 3 dif- ferent status indications:

Not Lit - Indicates that the unit is not plugged in or is not being supplied

AC power at the line cord.

Amber - Indicates that the unit is in standby state where it is being sup- plied with AC power at the line cord but it has either: 1) not received the sequencing trigger that will allow it to change to the fully-powered state if the Power Sequencing Switch is set to ON, or 2) the front Power Switch has not been turned ON if the Power Sequencing Switch is set to the OFF position.

Green - Fully-powered, the unit has either: 1) received the sequencing trigger if the Power Sequencing Switch is set to the ON posi- tion, or 2) the unit’s front panel Power Switch has been turned ON if the Power Sequencing Switch is set to the OFF position.

CH B Input Select Switch

Determines whether the amplifier's output channel 'B' sources its input signal from "B BAL INPUT" or "A BAL INPUT" connectors.

Note: When set to "IN A", "B BAL INPUT" connector and CH B "Input Sens" Switch are not active, but CH B level control and Lo-Cut Switch do work.

Input Sensitivity Switch

Each input has a user-selectable sensitivity switch.When operating with standard line-level source equipment, the input should be set for 1V. When operating with low-level source equipment, the input should be set for 0.1V.
