5. that there isn t any difference in sound yet 9 The filters are basically of the boost cut design This means that the level controls marked with and signs either boost or cuts the selected frequency band Further the MIDDLE section has got a frequency control for precise adjustment of the midrange 10 Gradually increase or decrease the level and vary the frequency of the middle filter when operating the middle filter Notice how the sound is effected An A B comparison can be made by toggling the filter active switch Proceed to the COMP LIMIT knob This control adjusts the compression and is useful when playing very dynamic or loud 12 Turn up the COMP LIMIT knob to mid and max position Notice how the peaks in volume will straighten out as you play harder and harder 13 Now go on to the BRIGHT and turn it half way up Play your bass The BRIGHT filter is a high pass filter which works on the highest fre quencies of the bass to give enhanced ambiance and presence 14 Finally proceed to the DRIVE control and try increase this setting gradually until maximum position for a heavily over driven sound This was a brief introduction and as you go on further in this manual you will learn how to use and utilize all of the useful features that the EBS HD360 offers GOOD LUCK REAR PANEL DESCRIPTION FUNCTIONAL DESCRIPTION REAR PANEL Q EFFECTS LOOP EBS HD360 is provided with an effect loop
6. For optimum basic signal level turn up the GAIN knob until the PEAK led starts flashing from the strongest signal from the instrument Note A correctly set GAIN is vital for the signal processing to work properly in the EBS HD360 COMP LIMIT A low noise compressor limiter that works fast and effectively tightening up the sound and preventing the bass head from saturating at peaks when approaching the headroom limit The COMP LIMIT knob sets the compression ratio 1 e The signal strength relation between the input and output the higher ratio the more compression The LED indicates the amount of compression during play dB DUT Threshold Internal dB IN FILTER ACTIVE This switch actives the filter section described under point 6 This switch can also be remote controlled by a foot switch See rear panel descriptions for more details FILTERS The filter section contains four enhanced performance filters BASS is a shelving type 12dB oct slope phase compensated bass filter with a wide gain range MIDDLE has an extended frequency range of 50 5000 Hz This filter facilitates total control over the mids with a wide bandwidth giving a natural and non peaking result using frequency dependent gain In addition at minimum setting this filter facilitates a notch function suitable for cutting an exact frequency or eliminating acoustic coupling TREBLE is a shelving type filter controlling t
