While you are free to give personal authorization to anyone else or to work on it yourself we will not honor claims for payment for parts or labor from you or from third parties However we and our dealers do try to be helpful in various ways 1 Our dealers will assist usually without charge during the warranty period in 3 determining whether there is a problem requiring return to the factory and b alleviating user error or interconnection problems that may be preventing the unit from operating to its full capability 2 We are available for telephone consultation if the dealer is unable to assist 3 If a part is found to be defective during the warranty period and you wish to replace it yourself we will normally ship the part immediately at no charge provided your warranty registration form is on file We reserve the right to request that the defective part be returned to us Shipping within the 50 United States You are responsible for getting the unit to our door at no cost to us We cannot accept collect or COD shipments We will return the unit to you prepaid at our expense using an expeditious shipping method normally United Parcel Service In areas not served by UPS we will ship by US Mail If you are in a hurry and want us to use a premium shipping method such as air express next day air etc be sure you tell us and agree to pay shipping charges collect If you specify a method that does not permit collect
5. 24 Chapter 3 Configuration B600 Profanity Delay Document Version 1 2 Configuration Variables A number of configuration variables are specific to either the Basic Remote or Extended Remote mod els these are covered in separate appendices BYP Bypass mode When the BD600 is bypassed internal relays normally connect the analog and digital outputs to their respective inputs This also occurs when the unit is powered down In some circumstances it may be preferable to change this behavior for example if the unit is fed with an analog signal but the output is taken from the digital output In this case DSP bypass may be preferred where the inputs and outputs are connected electrically according to the INPT configuration The BD600 may also be configured to MUTE its outputs when bypassed DISP Display Digits The number of digits after the decimal point showing the current delay amount in profanity delay mode The BD600 has a four digit numeric display used to show the delay amount in hundredths of seconds As the delay rebuilds or ramps to zero the last digit can change rapidly enough to be distract ing to the operator By changing the number of display digits to two one or even none this source of distraction can be reduced greatly or eliminated Since the operator may only need to know that the BD600 is in rebuild and whether it is safe or not the operator may choose not to have the delay time presented in such high resolution DLAY
6. 3 AU Press the WAIT AND EXIT button four times to go to the IN G variable Press the REBUILD or RAMP TO ZERO button to step through the attenuation values to achieve the desired amount of trim attenuation or gain The available range is 30dB attenuation to 10dB gain The trim adjustment affects the level meters as the adjustment is made Note that since the unit is bypassed not processing audio the output level is not affected by this adjustment unless bypass mode is configured for DSP bypass The level meters will show the input levels as you make this adjustment gt See Chapter 3 on page25 to configure bypass mode In most cases the combination of the input and output gain settings should be such that there is no level change when going in or out of bypass Once the adjustment is complete press the BYPASS button twice to place the unit in line Connect analog audio outputs The BD600 has an output level control again operated from configuration mode which can reduce the output audio by up to 30dB or increase it by up to 10dB The factory default is no attenuation To adjust the audio output attenuation repeat the above process except choose the OUTG variable in stead The range of this variable is 30 thru 10dB Note that since the unit is bypassed not processing audio the output level is not affected by this adjustment The unit will have to be placed in line press BYPASS twice to test the new value unless the unit has be
7. Delay Length Delay length controls the maximum length of the broadcast delay This adjustment may select a delay length of from 4 0 to 80 0 seconds Select a length allowing the operator to dump multiple offending phrases without impairing operator efficiency A length which is too short will not allow the operator enough time to delete offending speech while a length that is too long increases the amount of time required to exit from the delay at the start of a break or end of a show If MPD is selected the maximum delay is determined by the precision delay setting allowing the nor mal profanity delay functions to be used to enter and leave precision delay mode DUMP Dump Amount This is the amount of time deleted from the delay when the DUMP button is pressed in profanity delay mode If the DUMP button is pressed when less than this amount of time is in the delay then the entire contents of delay are deleted FLBK Fallback If AES EBU or Wordclock is selected as a sync source and there is no suitable signal present the unit will declare an out of lock condition If the unit is in line not in bypass and an out of lock condition exists the four digit display will scroll the message NO LOCK If the FLBK fallback variable is set to ANA analog then the analog input audio will be used until lock is restored The analog input will be sampled at either 44100 or 48000 the sample rate chosen being whichever of the two rates is closer to the AES
8. EBU sample rate last received by the unit or 48kHz if no AES EBU signal has been present since power up The AES EBU outputs will be active and the rate will be the same as the input analog sample rate If the fallback variable is set to MUTE the unit will mute the outputs until lock is re gained IN G Input Gain This controls an attenuator in the analog audio inputs of the BD600 The maximum level is 10dB 10dB of gain The minimum level is 30dB 30dB of attenuation While the meters immediately re flect changes to the input level configuration variable this control will not affect levels seen at the ana BD600 Profanity Delay Chapter 3 Configuration Page 25 Document Version 1 2 log outputs when bypassed This control should be set so that almost all of the meter segments light on a loud signal INPT Input source This variable determines whether the ANAlog or digital input is used If it is changed it will also change the SYNC variable if ANA is selected SYNC will be set to 48 if DIG is selected SYNC will be set to AES See Selecting the sample rate on page 9 JING Select current Jingle Select which of the four possible jingles ONE TWO THRE or FOUR on the Compact Flash card is active Note that the jingle file will only be recognized if it is in the correct format ABAD JINGLE message will appear briefly if an unsuitable or absent jingle file is selected See Jingle files on the card on page 15 for more i

Precision Delay mode The minimum fixed delay the BD600 will allow is 10 milliseconds The absolute delay time through the unit will depend on whether analog or digital inputs or outputs are being used Broadcast profanity delay functions such as rebuild are only operative in precision delay mode at delay values of 100 milliseconds and above The fixed delay writes data continuously into the 10 second buffer Changes in delay value changes the position of the play head not the record head That means that if the delay length is adjusted by ear the user doesn t have to wait for new input audio to check the adjustment As an example while listening to an audio source try adjusting the seconds digit upward It is easy to play the same 1 second piece of input audio ten times Changes to delay values are smoothed meaning that in most cases small changes can be made on air A large change will still be smoothed but the discontinuity in program material may be apparent BD600 Profanity Delay Chapter 2 Operation Page 17 Document Version 1 2 Chapter 3 Configuration There are a number of adjustable values used by the BD600 Configuration mode gives access to these values and allows them to be changed This chapter covers the configurable variables for the basic BD600 Configuration of optional features is covered in the appendices The configuration mode is operated by the front panel buttons which are used to navigate through a map of configura
