![]() ![]() For more custom installs, a single color can also be selected during slow-motion color change. A simple press of the end panel-mounted switch changes the color to one of several presets, slow-motion color change, or rapid flashing random color. Each Tarantula Electro amplifier features a 12-point RGB LED lighting system containing its own independent RGB control. We’ve maintained their stable performance but given them a unique appearance. This was done at the suggestion of the devices manufacturers.Tarantula amplifiers continue to dominate the Soundstream amplifier arsenal. Additional cooling may be required if the amplifier is located in a tightly con- fined area or when driving especially low impedance loads at extremely high levels. We parralelled the rectifiers only after derating them to 80% of there full rating. Soundstream Tarantula TXP1.18000D Xtreme Power 7000W RMS at 1 Ohm Class D Full Range Mono Amplifier 18000W Max Best Sellers Rank. Tarantula amplifier employs highly efficient circuitry, a custom-engineered heat sink, and a unique ChassisinkTM construction to maintain lower operating tempera- tures. At higher power levels the amps operated in Class AB mode. so the amplifier were working as ifv they were running in Class A mode. At low power the bias was higher than normal. The 1 ohm with the parralell diodes was used in the Class A amplifiers. The emitter resistors we used worked fine. Every time we had to switch devices to another production run we would double check the bias. Pretty impressive when you realize that the Reference series were designed to operate into 1/2 ohm per channel.Īs far as the bias goes all amplifiers were adjusted in the lab to just above the appearance of crossover distortion not at a predetermined voltage. Usung these devices we built over 120.000 amplifiers in 17 years, and we did not have any failure problems. Soundstream TXP2.6500D 2-Channel 2500W RMS Tarantula Extreme Power Series Class D Amplifier Max Power: 6,500 Watts RMS Power 4: 400W x 2 RMS Power 2. You could actually get away with less devices for the same power level. Especially if you put a filter in limitimg them to 100 ms, This information was determined by getting a SAO chart from the manufaturers, Motorola and TI, showing operation to 100ms, which increased the sOA to about 1.4x. The TIP102/TIP107 have a much better SOA rating. But he never looked at the Safe Operating Area. I'm guessing he switched to them because they were higher current devices. Those were used by the engineer that designed the Rubicon series. MOER, I never designed any amps using the TIP142/TIP147. I also can repair any Soundstream Old Ochool and Rubicon amps. If youi or anyone else has any more questions please feel free to contact me. ![]() Give me a better description of what you were asking and i will answer you. The tarantula was based on Pro amp that was part of Stewart World Series amplifier line. I had a Pro Audio brand named Stewart electronics. I also designed the tarantula and Davinci. I also designed all heat sinks, power and output connectors and rca input jacks. Also is it also true that the only issue with the amps were the ratings only spec'ed power supplies? Are you talking about thgere power ratings? Can anything be done with the factory D series amp to provide more margin in the power supply? Are you asking if you can get more power out of thge amps by modifying the power supplies? I designed the MC series, Reference series, the later CA series, Granite, uSA and SA series. I also added the CA100 an adaptation based on Nelsons original designs.Ĭould you give me a clearer description of exactly waht you mean when you asked. In the II series I re-laid them out on single PC Boards, then my company began manufacturing them. All I did tto solve this problem was to re-adjust the bias to a lower setting. A condition where the bias is set to high and over time the amps would overheat and shut down. They were laid out with point to point wiring which meant that they were not cost effective to build. Click to oystg, The original D60, D100, D200, CA40 and CA50 were designed by Nelson Pass. ![]()
