ALESIS RA300 MANUAL PDF

In addition, push connectors are very easy to set up. Twist the strands together, press the push terminal button, and feed the strands through the exposed hole in the push connector. However, Alesis realizes that in many applications the RA power switch will be left on and the RA, along with other gear, will be switched on by a master AC switch. As a result, room acoustics become less important since the primary acoustic interaction involves direct sound from the speakers rather than reflected sounds from the room. Page 20 One path goes from device A to ground via the ground terminal of the three- conductor AC power cord, but A also sees a path to ground through the shielded cable and AC ground of device B.

Page 20 One path goes from device A to ground via the ground terminal of the three- conductor AC power cord, but A also sees a path to ground through the shielded cable and AC ground of device B. Because ground wires have a small amount of resistance, small amounts of current can flow through ground and generate a voltage along the cable shield.

Page Chapter 4: Typical Applications For auditorium and live music use, the RA has sufficient power to drive a set of small-to-medium size club speakers.

The hookup diagram is the same as above, with an Alesis mixer feeding the RA, and the RA driving the speakers. Page Keyboard Amplification System With multiple keyboard setups, you may need a mixer to combine the keyboard outputs into a single stereo feed. The Alesis Mixer is ideal for this type of application. Page Guitar Amplification System 4. In this system, a guitar goes through a QuadraVerb GT to provide distortion, chorusing, reverb, and other effects.

In this setup, an Alesis mixer feeds a crossover that generates the separate high and low frequency splits. The low frequencies go to one RA which drives the low frequency speaker system; Refer All Servicing to Alesis Alesis has spent a great deal of effort researching power amplifier reliability. We believe that the RA is one of the most reliable amplifiers that can be made using current technology, and should provide years of trouble-free use.

After that, try the following techniques for specific problems. Turn down the volume controls. If the hum goes away, then the source of the hum is either in a unit feeding the RA, or in the input cables feeding the RA

Alesis RA300 - amplifier Specs

For example, a kick drum pushes air toward you on the initial transient, so a speaker reproducing a kick drum should have its cone push air toward you. If the polarity is reversed, the cone will suck air away from you. Even if the problem occurs for only a few microseconds, a pulse-stretching circuit will allow the LED to light long enough for you to see that a problem is occurring. However, the power is considerably greater than that provided by most "headphone amplifiers", which are often rated at 1 watt or below. If a low frequency signal in a multi-amplified system is applied to a high frequency transducer, the transducer can be damaged, and a loose connection can cause noise

Профессиональный усилитель мощности Alesis RA300

Численное значение в названии указывает на максимальную выдаваемую мощность в мостовом режиме. Усилитель можно использовать как в студии, так и в составе Hi-Fi комплекса. Отсутствие активного охлаждения делает усилитель бесшумным, по сравнению с другими профессиональными усилителями. В целом, внешне усилитель схож с протестированным ранее Behringer A Защелка на XLR разъеме отсутствует.
