Sound Performance Lab 9530 manual First steps, Drive to zero, center-position, Bass Sound to zero

When setting up the Tube Vitalizer for the first time, it is wise to approach the controls in a specific order. Use a CD as source. The Tube Vitalizer is designed to process stereo sources. Left and right channels are adjusted with one control.

Set-up positions (see front panel picture):

Drive to zero	(center-position)
Bass Sound to zero	(center-position)
Bass Compression to Off	(counter clockwise)
Hi-Mid Freq. to 3.5 kHz	(center-position)
Process Level to zero	(counter clockwise)

High Compression to Off (counter clockwise)

High Freq. to zero	(counter clockwise)
Intensity to zero	(counter clockwise)

1.Press the Activate Process switch. The sound remains unchanged.

2.Slowly move the Process Level control in from the extreme left. You will find that starting from the 9 o’clock position all frequencies above 3.5 kHz (initial setting Hi-Mid Freq.) are beco- ming more intense. Freqencies below this point are diminished. First set the Process Level control around 6.

3.The next step is to shift the Bass control from the zero position to both sides.Turn to the right:The bass sounds tight and dry.Turn to the left: The bass sounds soft and round. Decide on a bass sound of the desired amplitude. Use the Bass Comp. control to compensate for level changes. The LC Filter switch adds a passive LC filter to the RC filter network resulting in an even punchier bass sound.

4.Now start varying Hi-Mid Freq. The original setting is 3.5 kHz. Turn to the right: The programme material sounds brighter and gets more mids from about 1.5 kHz.The Hi-Mid Freq. control sets a starting frequency above which all frequencies are processed. If this starting frequency is lowered, the frequency spectrum included in processing increases. The programme material then sounds brighter and clearer.

Turning the control to the left shifts the starting frequency from

3.5kHz 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.

5.The High Freq. EQ helps you to give voices or other instru- ments in improved presence. Leave the High Freq. control in the set-up position (counter clockwise) and turn in the Intensity to 6. This makes the processed signal more natural with a soft, silky- sounding top-end. Use the High Comp. control to compensate for level changes.The LC Filter switch adds a passive coil filter into the RC filter network giving the sound more presence.

6.Finally you switch on the tube section by depressing the Activate Tubes switch. The standard solid-state output stage is exchanged by the tube output stage adding warmth and a smooth bottom end. The output level is controlled by the Attenuate-potentiometers.
