[. . . ] Turning the control to the left shifts the starting frequency from 3. 5 kHz to higher frequencies. The programme material then sounds increasingly dull, because fewer and fewer frequencies are being included in the process, the higher the frequencies become. The setting you choose is a matter of personal taste. This section helps you to give voices or other instruments in improved presence. Leave the High EQ control in the set-up position (counter clockwise) and turn in the Intensity to around 12 o´clock. This makes the processed signal more natural with a soft, silkysounding top-end. Finally, activate the Stereo Expander section by depressing the In switch and turn the control to the 12h-position. Note the soft spreading stereo image. STEREO M K2 9 Control Elements 2 3 4 1 5 6 7 8 9 1 Active Active switches a relay hardbypass circuitry for XLR and jack operation The Active function switches the Stereo Vitalizer MK2 on or off. The illuminated switch indicates that the Stereo Vitalizer MK2 has been activated. The Active function is a relay hard-bypass function that works on both XLR and Jack connections. In the event of a power failure the Stereo Vitalizer MK2 is automatically switched to hard-bypass (power failure safety). Drive 2 The Stereo Vitalizer MK2 features a Drive control that enables you to set the level at which the Vitalizer filter network operates. To run the unit hotter set the level between the center position (0 dB) and the clockwise position (+6 dB) with the proviso that the Clip LED on the front panel is not regularly flashing. This will achieve processing at a lower input sensitivity and will result in a more intensely processed sound. Conversely, in order to achieve milder processing, set the level between the center position (0 dB) and the counter clockwise position (-20 dB). The Clip LED lights up around 3 dB before the effect signal path is potentially overdriven. It is essential to avoid the Clip LED being lit up for any length of time. Sets the operating level of the Vitalizer filter network Clip LED illuminates 3 dB before a potential overload Bass Sound 3 The Bass Sound control is responsible for the `colour' or timbre. If you move the Bass Sound control to the right, you get a drier, percussive bass sound, known as Tight. As a result of this, on the right-hand side of the scaling points, there are squares which increase in size, in line with increased intensity. They symbolize the contoured Tight bass sound. 10 STEREO M K2 If the Bass Sound control is moved from the center position (0) to the left, the sound becomes very deep, soft, and warm. This is symbolized with round scaling points which also increase in size as the intensity increases. The further the Bass Sound control is shifted to the right or left of the center position, the more intensive the bass in question. However, Process must be positioned to the right of the 9 o´clock setting for the bass to be audible. You can always hear the original (dry) bass if the Bass Sound control is in a center position. [. . . ] When the Gnd Lift switch is set to off, the circuit ground is isolated from the chassis ground. The detachable power cord is a standard 3-wire type fitted with an IEC mains connector; the transformer, power cord and mains connector have VDE, UL and CSA approvals. On the secondary side of the power supply, an RC combination is used to filter out noise and hum voltages. Both half-waves are smoothed with 2000microF capacitors in the positive and negative supply path, and both lines use precision voltage regulators for optimum stability. [. . . ]
