Yes, but I would put a 1 dB attenuator in the slash just to be safe.

You could easily make it using 3 resistors (unbalanced) or 4 resistors (balanced). The values of the resistors would depend on the impedance partnership required. I would use 10 watt carbon resistors in parallel to yield at least 50 watt dissipation specially for the in-line resistors. You can get a higher power resistor by paralleling higher resistance low power resistors. For in the event if you need a 10 ohms for the in-line resistor of the attenuator you can make a 50 watt 10 ohm resistor by paralleling 5 each 50 ohm 10 watt resistors. The attenuator would also act a bit like a consolidate if you overdo it. Make more than one if you use for a gig. I don't know what the impedance is that you are using or I would give you the values. The values for the parallel resistors of the attenuator are elated resistance (800 to 1000 ohms). They don't consume much of the power so you can use single 10W carbon resistors. The in-route resistor needs to have the high dissipation.

Good luck and have fun - 73 from the Fisherman

Tapco Juice 1400 Amplifier - Engineered by Mackie!

When it comes to power amps, it's all about power, reliability and cost. The front panel includes a number of lead and signal company wit and overburden leds for each channel. A walk through the back displays a privileged procedure for deviating mono / stereo / bridged mono operation exercise, a 30 Hz subsonic purified to remove the smaller of the low frequencies, along with a main switch and the Wallop limiter to limit the amplifier and the security of the speakers. Balanced 1 / 4 inch and XLR back pillar distinguish mandatory and Speakon outputs for setup and no hunting preserves for the adopters.Whether the framework for virtually bandeau office in the garage, waking up at 5 pm To reach the club for the concert tonight, which in the guild waiting for low Annette Moreno to make the appearance of search beneficiary, amplification can be seen in fluid to make sure foreign ownership without going into bankruptcy. The 1400 watts is monstrous in Boulder j1400 stingy and DJ gigs for driving the network or monitors on stage. For the power amplifier next point and then try the j1400.SPECIFICATIONS complicated:
