The HS 1200 is a powerful 120 watt combo amplifier which includes a matched 8-ohm 12" bass speaker in a specially designed cabinet which can be used either flat on the floor or in its “KickBack” position for increased high-end clarity and directionality.
• A feedback-type input that accommodates a broad range of input levels (up to 15 volts), so that you can use the HS 1200 with pretty much any kind of bass, from passive models to those with active circuitry.
IN OUT VOLUME 1. Input jack - Connect your bass guitar to the HS 1200 here. This standard 1/4" unbalanced jack provides a wide range high impedance input and is specially designed to handle a broad range of bass pickup signals up to 15 volts (allowing you to use any kind of bass, including those models that contain active circuitry).

Guided Tour - Front Panel 3. Shape switch - When pressed in, the HS 1200 activates a special equalization curve that is designed to enhance the sound of your bass instrument. When out, Shape is inactive. For more information, see the “Effect of the Shape Control”...

8. Direct output - This standard male XLR connector provides a mic- level pre-EQ (and pre-Volume) balanced low-impedance output from the HS 1200. You’ll usually use this to connect the HS 1200 signal to a Direct Injection (DI) box or to an XLR mic input when interfacing with external sound reinforcement or recording mixing consoles.
WARNING: Because of the high power levels and low frequency content of the signal generated by the HS 1200, we recommend the use of the provided internal speaker only. If you do wish to...
To avoid potential overheating problems, make sure that the rear panel is unobstructed and that there is good ventilation around the entire unit. The HS 1200 may be used flat on the floor or in its “KickBack™” position (for increased high frequency clarity and...

4. Use a standard music instrument cable to connect your bass to the Input jack on the front panel. On the front panel of the HS 1200, turn the Volume control to its minimum (fully counterclockwise) position, set all three INPUT EQ controls to their “0”...

We recommend the use of large size headphones (those with large transducers) for optimum bass reproduction. 10. If you need to connect the HS 1200 to a live sound reinforcement or recording mixing console, plug a standard female XLR jack into the front-panel Direct Out output and connect it to a Direct Injection (DI) box or to an XLR mic-level input on the mixer.
The HS 1200 provides you with three bands of equalization. Each EQ knob (labeled Low, Mid,...

In many instances, the best way to deal with equalization is to think in terms of which frequency areas you need to attenuate, as opposed to which ones you need to boost. Be aware that boosting a frequency area also has the effect of boosting the overall signal; specifically, too much Low EQ boost can actually cause overload distortion or even harm a connected speaker.

(you’d be amazed how easy it is to forget these things!). As you experiment with the EQ controls of the HS 1200, don’t forget that your bass also provides EQ controls in the form of its tonal settings—this can be particularly effective in instruments that have active circuitry.
Effect of the Shape Control The HS 1200’s unique Shape control enables the sound of your bass instrument to be enhanced at the touch of a button. When the front panel Shape switch is pressed in, a special equalization curve is activated that is designed to improve the sound of most electric bass instruments.
