Product Details

The XS400 is a 400 watt 1x15 inch bass combo amplifier with tweeter. It's the next leap forward in bass amplification design from Yorkville Sound. The first major advance was to feature a Sovtek 12AX7A preamp tube at the input stage. Not content to stop there, we added a separate parallel tube overdrive circuit, and an innovative "wet / dry" balance control that allows the player to set the perfect blend of overdriven signal to clean bass tone. In short you can add as much growl or as little "tube warmth" to your overall bass sound as you need, while maintaining a clean tone underneath it all to maintain definition and clarity. A switchable limiter and a compressor circuit with user definable threshold control have been added to the tube input circuit as well.

An improved five-band EQ, with a semi-parametric mid control with a user definable frequency has taken the place of the graphic EQ Yorkville has used on higher power bass amps in the past. A new continuously variable "Scoop" control has been added to the XS400 to replace the "Contour" switch used on Yorkville bass amps in the past as well. The Scoop function sweeps from a flat frequency response to a mid-frequency dip at 300 Hz. As you increase beyond the 1/2-way point on the control you begin to boost both the top end and bottom end to your tone, in addition to further reducing the midrange level.

Other professional features added to the XS series bass amplifiers include a front panel wet / dry control for the effects return, footswitchable tube overdrive, footswitchable effects return and a pre / post selectable XLR balanced Tube DI output. Speakon and 1/4-inch extension speaker outputs have been added for the addition of an external bass cabinet, like our popular XC210, XC410, and XC115.

A feature unique and solely exclusive to the XS400 and XS400T is the "Tweeter Auto Mute" switch located on the rear panel. Under normal operating conditions the tweeter will automatically shut off when the Tube Drive is activated, whether by front panel control or footswitch. This helps to reduce the harshness in the higher frequency range that is typical of an overdriven sound going through a tweeter. If you desire the tweeter to be active in the overdrive mode then simply press the switch to disengage the mute feature. This is very handy if you typically do not desire an overdrive sound and set the tube drive setting off, or the wet /dry all the way to dry. This will allow you to either be able to shut the tweeter completely off by activating the drive channel and the Tweeter Auto Mute both, or even further use the footswitch to give you on/off control of the tweeter.

A front panel tuner / mute switch has been added to the XS400, XS400T and XS400H bass amplifiers. This mute silences the signal to the amplifier (and DI output) for silent tuning with the front panel mounted 1/4" tuner out jack.
