Make Your Bass Sound Bigger Than Life!Bass players, here's a way to get into the legendary SWR sound and tone-shaping features at an unbelievably low price! The WorkingPro 400 gives you classic SWR tone and clarity, the exclusive tone-expanding Aural Enhancer circuitry, 400 watts of dependable solid-state power and the tonal sweet spots of a simple 3-band active EQ with variable midrange. And with SWR's brand new Bass Intensifier circuitry, you can thicken your low-end response at the frequency range of your choice, making the 400 watts onboard louder than ever before. It's also rack-mountable!
SWR WorkingPro 400 Bass Amp at a Glance:
Size amd power for any size gigs
The WorkingPro 400 delivers famous SWR bass sound in a rack-mountable head that you can mix and match with cabinets for small, mid-size, or even large-venue gigs. With 400 watts RMS at 4 ohms (250 at 8 ohms), the WorkingPro 400 can punch through even the thickest mix to deliver round bass tones.
New Bass Intensifier makes your amp sound bigger!
SWR's exclusive Bass Intensifier circuit is a brand new feature on the WorkingPro 400 amplifier. This bass boost/compression circuit maximizes the onboard power of the amplifier. The Bass Intensifier takes a player-selected group of bass and lower-midrange frequencies and "intensifies" them to provide extra "meat" and "punch" to the attack of every note played. It actually makes the WorkingPro 400 sound like a 700 watt amp!
Unique Aural Enhancer control
A big part of the WorkingPro 400 "sound" is the SWR-exclusive Aural Enhancer circuit. The Aural Enhancer was developed to bring out the fundamental low notes of the bass, reduce certain frequencies that can "mask" fundamentals, and enhance the high-end transients. The effect becomes more pronounced as the control is turned up. The result is a more transparent sound. Listening to a passive bass on the WorkingPro 400 with the control set all the way down, and then turning it all the way up, can be likened to listening to the bass suddenly become "active."
3-band tone controls, plus a built-in limiter
Sculpting your own personal sound is important, and the WorkingPro 400 offers a 3-band set of level controls. The Bass and Treble controls are centered around 80Hz (Bass) and 5kHz (Treble), and each can cut or boost its band a maximum of 15dB. The Mid Range controls comprise a level control and a frequency control knob. A "center click" position defeats each control's function. The Workingman's 15 Limiter circuit is a soft-knee type limiter that prevents distortion of attack transients or peaks. The Limiter can be used as an effect and is also helpful in preventing speaker damage.
Active and Passive inputs
Whether your bass has active or passive electronics the WorkingPro 400 can handle it. Two separate and independent input jacks are provided so that the best signal-to-noise ratio can be obtained without overloading the preamp section. The Passive input has over twice the gain than that of the Active input. Both inputs can be used simultaneously without affecting the volume or tone of the other. A great alternative use of these inputs would be to plug your bass into the Passive input and practice along with a drum machine by plugging it into the Active input.
Multiple output options
The WorkingPro 400 also gives you plenty of output options. A balanced XLR output is provided, with no front-panel controls affecting its signal. Tone and output level are controlled only by the instrument plugged into one of the input jacks. Run an XLR cable from the balanced output to a tape machine, mixing console, etc. This output is also suitable for sending a signal to a house mixer in live situations. The To Tuner send jack allows you to connect your instrument tuner to the WorkingPro 400 without having to unplug and go back and forth from amp to tuner to amp. An extension speaker jack makes adding speaker cabinets to your rig easy, and a sidechain effects loop allows connection of outboard effects processors. To top it off, the WorkingPro 400 includes a headphone jack to let you practice without disturbing your neighbors!
