Page 6: Getting Started
Exact voltage and frequency compatibility is stated in the specifications section. Once the 3050 Power Amplifier is connected to a live mains outlet, an outline of the power button on the front panel will become illuminated and blink for a short time. The outline will then glow white steadily, indicating that the supervising microprocessor is powered up and the amp is ready to be turned on. - Page 7 Getting Started...

Page 8: Connecting To A Balanced Source
Boulder ABL2 Input Adapter. It converts a balanced input into an RCA input right at the rear panel of the 3050. Like the above cable, the minus input of the 3050 is connected to the ground of the RCA connector. However, this minus side will then share the shield wire with the chassis ground and will not have very good hum rejection. - Page 9 Getting Started UNBALANCED INPUT CABLE 2-POS INPUT 3-NEG INPUT 1-GROUND...

Page 10: Polarity
Please note that the 3050 Mono Power Amplifier conforms to the standard of pin 2 as the “high” or “hot” pin for the balanced input. The Polarity of the 3050 Mono Power Amplifier is such that a positive-going transition at pin 2 will produce a positive-going transition at the “+”... - Page 11 Getting Started...

Page 12: Operation
Powering Up With all your connections made, you are ready to listen to your Boulder 3050 Mono Power Amplifier. To turn the amplifier on, press the POWER button on the front panel. The amplifier will perform a warm up cycle and the power-button indicator will blink white and red. - Page 13 Operation...

Page 14: Input Dc Offset Voltage Detection
Clip Detection Clipping of the waveform results when any amplifier is driven at too high a level. A clip detection circuit is included in the 3050 Mono Power Amplifier. The indicator will indicate clipping by momentarily turning from white to red. Both voltage and current modes of clipping will be detected, although generally it is only voltage clipping which occurs. - Page 15 Operation...

Setting Boulderlink Switches Every Boulderlink system must have one, and only one “MASTER” component. Usually this is the preamplifier. In the case of the 3050 Power Amplifier, one channel should be set to “MASTER” as long no preamplifier is connected by Boulderlink. Other Boulderlink products which do not have... - Page 19 Boulderlink BOULDERLINK "DAISY CHAIN" TO ALL OTHER SLAVE BOULDER BOULDER BOULDER UNITS PRE- POWER POWER AMPLIFIER AMPLIFIER AMPLIFIER MASTER SLAVE SLAVE...

Page 20: Setting Boulderlink Id Numbers
Setting Boulderlink ID Numbers Every component is required to have a unique Boulderlink ID number. Each Boulder 3050 Mono Power Amplifier has an amplifier ID switch on the rear panel. Starting by setting the first switch to “0” or “1” by pressing on the either button above or below the ID window. - Page 21 Boulderlink...

Page 22: Boulderlink Messages
Boulderlink Boulderlink Messages Each component in the system can send a message to the preamplifier which is then shown on its display. This is particularly helpful in confirming the operation status of each power amplifier in a multiple amplifier system. Typical messages on a 2010 Preamplifier are as follows. “AMP 1 Error”... - Page 23 Boulderlink...

Page 24: Fault Conditions
Fault Conditions Fatal Errors If the indicator of the 3050 Mono Power Amplifier blinks white rapidly for a short time and a series of red flashes follows, a fatal error has occurred. The indicator will flash red in a specific sequence, defining its error code to an authorized Boulder technician. - Page 25 Fault Conditions...
