SWR WORKINGMAN'S 10, Руководство пользователя, Страница: 17 / 24

NOTE: Generally speaking, you should try the Passive input jack first. If you hear a small amount of
distortion and the Preamp Clip LED is not activated, try using the Active input jack. And please note,
some passive pickups DO distort. Because of the hi-fi nature of all SWR products, even the smallest
amount of distortion originating at the source (instrument) may be heard.
Active Input
The Active input jack should be used with instruments having a built-in (on-board) preamp that will pro-
duce signals over 1 volt RMS. Some really “hot” pickups installed in your instrument may find the Active
input more compatible. The best judge is your own ears.
NOTE: Using the Active input with passive basses may result in a loss of high-end transients.
Players who roll off their high-end starting at around 2kto 3kHz may find this input more to their
liking.
If your hear some distortion from your active bass and are using the Active input jack, check your
battery. Also, make sure the Preamp Clip LED is not lighting.
PREAMP CLIP LED
The Preamp Clip LED will light whenever the Preamp, Tone section or output buffer reach clipping (that
is, run out of headroom). In the event the Preamp clip indicator lights, turn down the Gain
control. Since the Preamp Clip also monitors the Tone section, boosting any one of the tone controls
can cause the LED to activate. Again, turn down the Gain control if this happens.
NOTE: Constant clipping of the preamp will not harm the electronics in your Workingman’s 15.
However, damage can occur to speakers due to near-DC content present in a clipped waveform.
GAIN CONTROL
The gain control adjusts the volume of the preamp section. After the Tone controls, Aural Enhancer and
any effects you may be using have been set to your liking, the Gain control should be set to where the
Preamp Clip LED barely flashes upon hitting your loudest note. After setting the Gain, use the Master
Volume to set the desired volume level. Using these controls in this manner assures the maximum sig-
nal-to-noise ratio with no distortion caused by the preamp circuits clipping. Since the Gain control is
similar to a “pad,” a small amount of signal will get through with the Gain control turned all the way
down. The Gain also adjusts the level sent to the Effects send jack. If your effect is being overdriven,
turn down the Gain control.
TONE CONTROL SECTION
The Workingman’s 15 Tone Control section is a three-band set of level controls. The Bass and Treble
controls are centered around the frequencies 80 Hz (Bass), and 5kHz (Treble). The Mid Range controls
comprise a level control and a frequency control knob.
Each control (except Mid Frequency) can cut or boost its band a maximum of 15dB. Each control has a
flat (“center click”) position that defeats its function. In this position, the tone controls are inactive.
For each tone control (except Mid Frequency), rotating the knob counter-clockwise from the center click
position will reduce or cut its designated frequency. Rotating the knob clockwise will boost its designated
band or frequency.
Using the Tone Controls
To get the most out of the Tone Controls of your Workingman’s 15, it would be best to first understand
how the Aural Enhancer works, and how it interacts with the bass, mid range and treble controls. Think
of it as a variable tone curve, changing with its position. As you raise the control from its “0,” or fully
