8. ching the unit on with the power switch at the right hand side of the front panel the display will initially show 80 for several seconds and will then show 2 This process is carried out every time you power and allows time for the BD80S to clear any random data from the audio memory and boot up its computer The 2 stands for 2ms the current rear edit position and means the unit is ready for operation FRONT PANEL If you hav ver used a delay unit before you will be acquainted with the controls on the left half of the front panel Those on the right will need explaining because they perform functions in the delay and sampling modes If you are in a hurry to use the unit then you will probably have started already so turn to the sections on Delay p 4 and Sampling p 5 although you would do well to read this section at sometime in case you miss some thing obvious So let s have a look at the front panel in some detail starting from the left Level Indicator This four LED bar 2 yellow I green I red gives a visual indication of the input into the unit Trim Recessed inside this hole is a small pre set that allows you to adjust the trigger threshold when triggering a sample by an incoming signal to the unit More about this in the section on Triggering p 9 but for now be careful not to damage the slot This pot adjusts the input into the unit Use in conjunction with the level indica
9. e on front edit only Press ED F LED on Press SHFT and an increment button either up or down This causes a change in the front edit point of 30 us Holding down an increment button while pressing SHFT causes the ms display to change very slowly as you are now dealing with 30 us steps Listen to the recording by pressing the manual trigger button Multiple samples can be stored in the memory For each successive sample move the new sample s front point to the end point of the previous one and carry on as normal Repeat this procedure until you run out of memory To hear all the samples played back one after the other set the front point to the beginning of the memory and the end point to the end of the very last sample To reset edit points both front and rear 0 and 2ms press SHFT and ED F This also sets pitch to concert 60 Once you are satisfied with your sample turn to the section on Triggering p 9 or if you want to pitch change it refer to the section on Pitch Change P8 PITCH CHANGE To pitch change a sample in semitones press PTCH LED on The display shows 60 this is the sample original pitch and can be altered by the increment buttons where one nudg quals one semitone The maximum variation is one octave down 48 and one octave up 72 To cancel pitch change return to concert pitch press T and J simultaneously PITCH MODE ONLY Fine Pitch Change This allows th

11. es double tracking effects can be obtained with settings up to about 60ms but use your own ears Modulation effects can be created by switching in the modulation section press MOD button and selecting a delay time between 2 and 20ms By altering the modulation speed and depth controls together with the feedback control you will be able to achieve some very rich chorus and flange effects By switching in feedback phase reverse FBO and delay reverse DELO you will be able to explore other tonal possibilities The secret is to use your own ears BEL are offering you great flexibility so make the most of it After using this method of delay control you will find other digital access methods cumbersome Use the mix control to mix the dry signal with the effect signal Press the BYP button to kill the effect You can summon up a delay time of 13 106s by pressing the MONO button but the output will only be from the right channel SAMPLING The BD80S allows you to sample up to 6 553s of stereo material or 13 106s of mono material output through the right hand output It also lets you store any number of samples in memory provided that their total time does not exceed that of the available memory The unit can also sample into the right and left channels separately Samples can also be treated with the modulation section There are two methods of sampling variable length and fixed length When listening to the material to be

15. tor to get a level that keeps the green LED on most of the time and occasionally peaks into the red Keep an eye on the level indicator as maintaining a correct level into the unit is one of the simplest ways of ensuring that you receive the highest performance from the BS80S Pay particular attention to it when adding regeneration to the delay chain Mix This pot controls the mix of the dry or unaffected signal and the effect full clockwise gives the delayed signal in isolation Use the latter when connecting to the effects return on a mixing desk The pot is notched at the centre wher qual amounts of both signals are present Feedback This pot controls the amount of regeneration of the delayed signal i e multipl choes When using this keep watch of the input level This pot controls the output level from the unit and allows you to match it perfectly to your use This pot works in conjunction with the Depth pot next in the modulation section which is switched in with the MOD button Clockwise rotation increases the speed of modulation You will have noticed a yellow LED to the right of this pot and this gives a visual indication of the speed Turn the knob and see for yourself Depth This pot controls the depth of modulation With it turned fully clockwise you achieve the maximum depth of modulation Put a signal through and listen The next thing we come to is a cluster of 6 buttons BYP
