Etapas amplificadoras para sub HUM. Información compilada.

Iniciado por jalejos

Cuando pases por Valencia, nos vamos a casa de Lorac para demostrartelo. Aunque reconozco que lo que ofrece la iNuke por ese precio, no se puede igualar (ni las luces de feria )

Las Inuke están analizadas y dan prácticamente la potencia que declara fabricante. Si las Hypex dan esos 180w no pueden con las Inuke (évidentemente alimentadas con la sensibilidad adecuada). Ahora... si el fabricante miente y esas Hypex dan seis o siete veces la potencia que declan ya es otra historia

Échale un vistazo a este enlace donde testean la inuke Nu6000 y puedes ver toda clase de gráficas. No voy a entrar en alguna pitufada comentada sobre el sonido pero las mediciones objetivas (lo que nos interesa) son irrefutables :

So, on to the results, first up, the continuous tone tests.

8 Ohms:
The Behringer was happy to drive 8 Ohm loads at full power (limiter active) for 1 minute without any change in power output. With both channels driven it produced 1.17kW at 1kHz and 1.08kW at 31Hz.

4 Ohms:


The Behringer was happy to drive 1 channel at 4 Ohms with no reduction in output at 1 minute. Power output was 2.27kW at 1kHz and 2.12kW at 31Hz. This demonstrates that the amp section should drive high power into 4 Ohms without any short-term limitation. However, when driving two channels simultaneously the amp would trip its protection and shut down, needing a power on/off cycle to reset. Since the power amp part was happy to deliver the power then I conclude there is a total power limit on the supply part and rather than engaging the limiters to reduce output the amp switches off. This seems a strange decision on the part of the designer, better the show go on at reduced level if the amp finds itself producing sine-wave like power outputs. It is only fair to remember however that this is a harsh test and the amplifier was pulling 24Arms from the mains at the point it cut-out! (Note: the 12A breaker on the rear did not operate as it has a time delay, this was an internal electronic limitation).
Whether this ever occurs in a music situation is debatable and the burst tests below will demonstrate its actual ability with more realistic signals. That said it does mean it is possible to trip the amp if you abuse it into 4 Ohms, not ideal.

If the output power was kept below 1.7kW per channel then the amp would not trip. To leave a margin I left the amp running at 1.5kW per channel to see if I could get a 1 minute figure. Unfortunately after 15 seconds the circuit breaker opened, not surprising at it was drawing 22A from the mains at the time. So in the end I didn't get a 1 minute figure for 4 Ohms running but I expect it will be around the 1.2kW per channel mark as that produces a current draw of 15A which would eventually trip the breaker

People often say how come they can get away with a 10A IEC inlet then? Well thats because the safety regulations require an audio amp to be tested at 1/8th its rated power as this is generally agreed to be representative of normal music played at just clipping levels. Thats why the behringer says "620W" on the back of it: 2 channels of 2.3kW = 4.6kW, divide 8 is 575W and hence with some losses it will draw 620W from the mains. In theory this should be the "worse case" but as I've already said, used as a bass amplifier and driven into limiting the average power output will be much higher than 575W! It would be interesting to see what power it can be made to pull when used with a system and driven hard, I suspect it will be lower than you think!

Y es que la propia behringer ya lo deja claro:

there is an interesting read at Soundforums.net-Behringer-iNUKE-NU6000-amplifier

quote of Post 31 in this linked thread:
Right finally after two e-mails to Behringer asking whether the iNuke 6000 amplifier's specs are RMS or Peak, they finally tell me, they're Peak power, so I guess that means the amplifier is only capable of outputting in the region of 750-900 watts RMS per channel and even that might be burst right?

750-900 RMS por canal garantizados... potencia que dudo sobremanera alcance la Hypex que declara 180W
