INTRODUCTION The Beta Bass Processor offers the professional bassist the highest level of performance that only ISP Technologies can provide. By incorporating our patented Time Vector Processing, the compression circuitry becomes the most adaptive to be used in a bass processor as it allows the Beta to truly track the signal of the exact notes played.
FRONT PANEL 1. INPUT JACK This ΒΌ-inch mono jack provides the high impedance for connection to your bass . 2. GAIN Adjust gain until the red LED barely flashes. 3. BASS Controls the low frequency level. 4. MIDRANGE 1 Controls the low/midrange. BOOST/CUT controls the level at the frequency selected by the FREQ control. Bandwidth switch selects wide/narrow bandwidth. 5. MIDRANGE 2 Controls the high/midrange. BOOST/CUT controls the level at the frequency selected by the FREQ control.
REAR PANEL 1. 9VAC POWER INPUT JACK Supplies power to the unit by plugging in a 9V AC adaptor. 2. PRE/POST CONTROL Controls the source of the DIRECT OUTPUT. PRE takes the DIRECT OUTPUT before the MASTER VOLUME control and POST takes the DIRECT OUTPUT after the MASTER VOLUME control. 3. GROUND LIFT CONTROL Disconnects the ground pin (#1) of the DIRECT OUTPUT. This is useful for solving hum problems. 4. DIRECT LEVEL CONTROL Controls the level of the DIRECT OUTPUT. 5.
When properly used, the Decimator should be completely transparent; it should have no effect on the audio signal other than to remove the background noise. To maximize the performance of the Decimator, it is necessary to understand both the operation of the controls and the principles of how the internal circuit operates. After this understanding, it will be easier to set up the Decimator to suit any application.
SETTING THE DECIMATOR THRESHOLD Start by setting the Threshold for minimum, full counterclockwise. Turn the Threshold control clockwise until the desired effect of the downward expander is achieved. The expander should start to operate when there are gaps in the audio or as the input signal gets close to the noise floor. NOTE: Setting this control to high will cause the expander to start to cut off the input signal to soon.
