Panel Descriptions
Black Max Rear Panel
1 . Speaker Terminals - Connects to 70V constant voltage speaker loads. One set for each amplifier section. Accepts up
to #
1
0 AWG wire or spade lugs for speaker system connections.
2. Ground Terminal - Provides convenient access to earth ground.
3. Automatic Sleep Mode - Allows the unit to automatically put itself into a sleep mode when there has been no input
activity for more than 3 minutes. In sleep mode, the amplifier’s idle power is greatly reduced. The amplifier immediately
and noiselessly returns to its full-powered state when a signal is detected at an input. Flush switch actuators reduce tam-
pering.
4. CH B Input Select Switch - Allows output Channel B to source its input signal from either "A BAL INPUT" or "B BAL
INPUT".
5. Lo-Cut Filters - Roll off frequencies below 60 Hz (2nd order) to prevent saturation of speaker transformers. Flush
switch actuators reduce tampering. One per channel, high pass.
6. Fan Exhausts - Cooling air outlets for independent, variable speed cooling fans. One per channel.
7. Line Cord - AC mains input line cord. Note: The X600 requires a 20A, 1 25V AC power receptacle because its maxi-
mum current requirements exceed the capacity of a typical
1
5A receptacle. The 20A receptacle is a NEMA 5-20R style.
8. AC Power Status Indicator - Indicates the AC power status of the Black Max amplifier. When the indicator is not lit,
no AC power is applied to the line cord. When lit amber, power is applied to the line cord but no sequential trigger has
been received to place the amplifier into a fully powered-up state (or power switch is OFF). When lit green, the amplifi-
er is fully powered.
9. Power Sequencing Switch - Turns power sequencing ON or OFF so that an amplifier can be controlled by either its
front circuit breaker switch or by another Black Max amplifier. Flush switch actuators reduce tampering.
1
0. Power Sequencing Inputs - Multiple Black Max amplifiers can be wired together in a daisy chain to allow for controlled
sequential power-up. A pluggable screw terminal strip is provided for easy installation.
11
. Input Sensitivity Switch - Allows the unit to reach full power at either line-level input (
1
V) or low-level input (0.
1
V).
One per channel.

2. High-Impedance Balanced Inputs - Pluggable 3-position screw terminal strips allow for easy installation and provide
convenient connections to high-impedance balanced inputs. One per channel.
1 3. Input Level Controls - Continuously variable input level controls. One per channel.
