Cool Running = Reliability, Speakon Cables

1001RB Series

Tech Talk

Cool Running = Reliability:

The 1001RB Series uses a “dual rail power supply” that generates about half the heat of conventional amplifiers. Low output signals run off a low voltage supply, and high level signals run off a high voltage supply. This keeps the amp running a lot cooler and makes it much more reliable. To cool the amp when its being driven hard, we’ve designed a temperature sensitive fan cooling system. When the amp is under a light load, the fan is off or running at a low speed, reducing fan noise. As the amp works harder, the fan speed increases to keep everything cool.

Smart Protection Circuitry:

The 1001RB’s protection circuitry constantly monitors for unsafe operating conditions such as short circuits, miss- wired speaker cables, blown speakers, improper ventila- tion and incorrect speaker configurations. In addition, protection is provided during power up/down. If the 1001RB senses any unsafe operating conditions, the output signal is immediately muted and the power light changes to from Green to Red. The amplifier will remain muted until the fault is removed. If the protection circuit activates while playing, turn the amplifier off and check the amplifier speaker output connections. Be sure that you are not exceeding the maximum recommend load described in this manual. Also, check to see that you have connected the amplifier to your speakers as described in Bi-Amp and Normal Operation on page 7. If the problem persists, contact GK directly for advice.

Low Noise Operation:

The 1001RB Series uses a high gain, high headroom, low noise input stage. It has such a large dynamic range (60v p-p) that very few instruments can overdrive it. Even most basses with “active” electronics do not need the input attenuator to be set. The benefit to you is less hiss from your horn, and over all, much less noise.

Speakon Cables:

To make use of the 1001RB’s Bi-Amp feature you will need to use the four conductor Speakon cable (provided with the 1001RB head, and included with the combos for connection to the internal speaker) to connect to a GK RBH Series cabinet. This specially designed cable carries the signals for both amplifiers (540W Woofer Amp and 50W Tweeter Amp) to the speaker cabinet. Plus, they are the coolest speaker connectors currently available. Below is a table describing the Speakon cable connections to the 1001RB head and combos.

Speakon Pin #	Signal	WireColor
1+	540W Woofer Amp +	White
1-	540W Woofer Amp -	Black
2+	50W Tweeter Amp +	Red
2 -	50W Tweeter Amp -	Green

To obtain an additional 4 conductor Speakon cable for use with the 1001RB please contact your local

dealer or contact GK directly.

In Closing:

You should now have a thorough understanding of how your new 1001RB Series amplifier works and what advantages it can offer you in getting “your” sound.
