Bass Sound That's Loud and Proud!

It’s SWR’s newest big-gig powerhouse, the WorkingPro 700 – an amp that works as hard as you do! Loud and proud at 700 watts, and packed with new features and professional, time-tested SWR tone, the WorkingPro 700 is destined to become the newest classic SWR amplifier. The lightning-quick solid-state preamp and renowned Aural Enhancer circuitry provide natural warmth and crystal clarity, while the 3-band active EQ lets you dial in your tone in seconds flat. Then add in the brand new, exclusive Bass Intensifier - which literally thickens the low-end response at the frequency range of your choice – and you’ve got an amp that will last you through gigs of any size and style. Get into the WorkingPro 700 and get some respect!

  • 700 watts of power for any size gig
  • New Bass Intensifier makes your amp sound bigger!
  • Unique Aural Enhancer control
  • 3-band tone controls, plus a built-in limiter
  • Active and Passive inputs
  • Multiple output options

Size amd power for any size gig
The WorkingPro 700 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 700 watts RMS at 4 ohms (450 at 8 ohms), the WorkingPro 700 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 700 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 700 sound like a 700 watt amp!

Unique Aural Enhancer control
A big part of the WorkingPro 700 "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 700 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 700 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 WorkingPro 700 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 700 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. you can also engage the built-in 10dB pad to tame overly aggressive inputs.

Multiple output options
The WorkingPro 700 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 - with a new Mute function - allows you to connect your instrument tuner to the WorkingPro 700 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 700 includes a headphone jack to let you practice without disturbing your neighbors!
