  • Page 3 SWR’s world-renowned Professional Line of products for bassists. A little history: The SWR 350x is an upgraded version of the Bass 350, a model we’ve offered for over ten years as a simple and straightforward solution for bassists who wanted the famous “SWR Sound" in the simplest Professional Line package possible.
  • Page 4 Note: Please take a moment to verify that the following items were included in your SWR 350x packaging: AC Cable, User Guide, SubWave Activator Footswitch, 1/4" to 1/4" Footswitch Cable, SWR Catalog. 350X • FRONT PANEL FEATURES • Dual independent input jacks compatible with both passive and active instruments •...
  • Page 5 350x’s Speaker Output jacks to the input jacks of your speaker cabinet. If your cabinet is a 4 ohm enclosure, the 350x will deliver 350 watts into it. If your cabinet is an 8 ohm enclosure, it will deliv- er 240 watts into it.
  • Page 6 Control about one large hash mark on the dial. Now turn up the Master Volume control to an equal level. You should now hear the sound of your instrument amplified through the 350x into your speaker cabinet(s). 350x • FRONT PANEL FEATURES Input Jacks Both input jacks accept a standard 1/4"...
  • Page 7 10 dB or more, you may find the Active input more compatible. The best judge is your own ears. If you’re using a keyboard or bass pedal with the 350x, we have found the best choice to be the Active input.
  • Page 8 SubWave™ Controls Based on the circuit from SWR’s groundbreaking Mo’ Bass Soundstation, the SubWave™ on your 350x is a lightning-quick sub-octave wave engine with tracking superior to other models of sub-octave effects cur- rently on the market.
  • Page 9 “Effects Loop” in the “Rear Panel Features” section later in this guide). Limiter/Compressor Circuit The Limiter found in the 350x is a soft knee type limiter. The Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, the Limiter is driven by the Master Volume control.
  • Page 10 If you are using an external effects device in the effects loop, that signal will also be pre- sent when in the LINE position (dictated by the setting of the Effects Blend control on your 350x). When in this position, the output level will be affected by the Gain control on the front panel as well as the XLR Pad control.
  • Page 11 Note: Turn off transients appear at the Balanced Output when the amplifier is shut down. We rec- ommend that equipment being used in conjunction with the Balanced Output be turned down, off, or disconnected BEFORE the 350x is turned off. XLR Mode Switch (Line/Direct/Direct + Sub) This three-position switch determines the signal present at the Balanced (XLR) Output jack as described in the section directly above.
  • Page 12 To use this feature, connect a shielded patch cord from the Tuner Out jack on your 350x to the input jack on your tuner. Turn the amplifier on and you’re ready to go. If you do not wish to monitor your sound during the tuning process, you may turn down the Master Volume.
  • Page 13 Be sure to leave at least a 1/2" clearance between the vent on the sides of your 350x and the sides of any rack case or enclosure in which you install your amp. This will allow for the heat generated by internal components to escape.
  • Page 14 • One 4 ohm speaker enclosure The optimum operating impedance for the 350x is 4 ohms. This way you get a good amount of power from the amp (350 watts) without operating too closely to the minimum impedance—or, in simple terms, with- out running the amplifier too hot.
  • Page 15 Yes, but one speaker cabinet will get more power—and be louder—than the other. Since your 350x is a mono amplifier, it is best to use cabinets of similar imped- ances when using more than one. The best two-cabinet setup is to use two 8-ohm enclosures.
  • Page 16 Only SPEAKER CABLE of 18 gauge or heavier (the heavier the cable, the lower the gauge) should be used to connect your 350x to your speaker system. Do not use shielded instrument cable to connect your ampli- fier to your speaker enclosure, as this can result in intermittent power loss, cause your amp to oscillate and damage itself and/or your speakers, and render the cable useless for any purpose.
  • Page 17 The 350x takes up two full rack spaces (3 1/2"). If the rack in which you mount your 350x requires that the rubber feet on the bottom of the chassis be removed, please remember to keep the screws handy in case you wish to reattach the rubber feet at a later date.
  • Page 18 The chassis of your amplifier can get quite warm during normal usage. This is especially true if you are operating your 350x at a 2 or 2.6 ohm total impedance. This is because these low impedances are intro- ducing the least efficient condition of the unit (in terms of power drawn from the outlet in relation to power produced in the speakers).
