BLACK BEAUTY – FRONT PANEL FEATURES INPUT JACKS Both input jacks accept a standard 1/4" phone plug and both inputs can be used at the same time. Since the two inputs are totally independent, no loss in volume or tone will occur by using two instruments simultaneously. However, the main applicational use for the two separate input jacks is th[...]

headroom). This function does NOT monitor the first tube stage of the Passive input. See that section for more info. In the event the clip indicator lights, turn down the Gain control. Since this circuit monitors the tone controls, boosting any one of them can cause the clip LED to activate. Once again, you may leave the tone control at its desired[...]

“MAX,” the “clean” bass signal will still be present…along with plenty of sub-octave effect. As always, your ears and the desired musical application will be the best judge in setting this control. (Keep in mind that the Bass Level control will have a significant impact on the perceived level of the SubWave™ effect as well, as it follow[...]

EXTERNAL effects unit. (In other words, it has nothing to do with the SubWave™ effect onboard your Black Beaut y .) With the Effects Blend fully counter-clockwise (“DRY”), no signal from your external effects unit will be heard. As you turn this control clockwise, more of the effect can be heard in the overall sound. When the Effects Blend co[...]

8 • BLACK BEAUTY OWNER’S MANUAL BLACK BEAUTY – REAR PANEL FEATURES BALANCED (XLR) OUTPUT The Balanced XLR out is a true electronically balanced output, suitable for studio and “front-of-house” (live) mixing consoles. The level present at this output can be adjusted by using the XLR Pad control (see the “XLR Pad Control” section below [...]

BLACK BEAUTY OWNER’S MANUAL • 9 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. In simple terms: 1. Direct = pre-EQ and SubWave™, post-first tube stage 2. Line = post-EQ and SubWave™ 3. Direct + Sub = pre-EQ/post[...]

Effects Blend Control is in the full counter-clockwise (“DRY”) position, no effects will be heard. This is normal. CONNECTING AN EXTERNAL EFFECTS DEVICE TO THE BLACK BEAUTY EFFECTS LOOP Obtain two high-quality shielded patch cables, preferably as short as possible. Route them in the most direct way possible. (Running patch cables over the top o[...]

TWEETER MODE SWITCH This three-position switch gives you the choice of three different options for operation of the horn tweete r . In the Full Range (top) position, the tweeter will reproduce an unattenuated signal of every frequency it sees (roughly 2 kHz up to 15 kHz, within certain tolerances). The –6db (bottom) position reduces the level of [...]

if someone tells you that they have a “4 ohm power amp,” their terminology and understanding of the con - cept is way off the mark. Unlike power amps, every speaker cabinet has a pre-determined impedance rating measured in “ohms.” In most cases this rating is either 4 or 8 ohms (though there may still be some old 2 ohm creakers out there). [...]

more during peaks), but since it has a higher impedance (8 ohms) than the internal speaker (4 ohms), it will receive slightly less than half (200 watts) the total power delivered. Other than this imbalance, there is no reason why you can’t connect an 8 ohm extension cabinet together with the 4 ohm internal speaker in the Black Beaut y . In any ev[...]

3AG, 10 amp, fast-blo. Do not defeat the purpose of this feature by using a higher rated fuse as it can damage your amplifier and void your warrant y. The fuse can open as a result of a fault in the speaker cable, the speakers themselves, or the power amp being sent well into clipping. With this in mind, it is wise to carry extra fuses at all times[...]
