User manual ROCKTRON THUNDER

[. . . ] Your Blue ThunderTM has been tested and complies with the following Standards and Directives as set forth by the European Union: Low Voltage Directive(s): Council Directive(s): Standard(s): Safety: 72/23/EEC 89/336/EEC (93/68/EEC) Electromagnetic Compatibility EN55013, EN50082-1, EN55020 IEC 60065 This means that this product has been designed to meet stringent guidelines on how much RF energy it can emit, and that it should be immune from other sources of interference when properly used. Improper use of this equipment could result in increased RF emissions, which may or may not interfere with other electronic products. To insure against this possibility, always use good shielded cables for all audio input and output connections. Also, bundle audio cables separately from the AC power cables. [. . . ] The PARAMETER SELECT control will allow you to access each of the following Compressor parameters. The PARAMETER ADJUST control will allow you to make adjustments to be made to the selected parameter: COMPRESR I/O The COMPRESSOR I/O parameter determines whether the compression circuit is active or bypassed for the current preset. Select IN if you want activate the compressor Select OUT if you want to bypass the compressor COMP THRESH The COMPRESSOR THRESHOLD parameter determines the input level (in dB) at which compression will begin. Lower settings of this parameter will result in more compression. The COMPRESSOR ATTACK parameter determines the speed (in milliseconds) at which the compressor will reach its maximum compression level after the input signal has exceeded the threshold level (set by the COMPRESSOR THRESHOLD parameter). The COMPRESSOR RELEASE parameter determines the speed (in seconds) at which compression will cease after the input signal has dropped below the threshold level. ***NOTE - We suggest you use longer release times - up to 1 to 2 seconds. This will keep the dynamic range limited producing a more smooth consistent level output. **** COMP ATTACK COMP RELEASE 19 Functions and Parameter Descriptions DELAY Function Delay provides a reproduction of the input signal, occurring at a prescribed time (usually expressed in milliseconds) following the input signal. The Blue Thunder provides two discrete delays (Delay 1 and Delay 2), each of which has its own set of parameters to determine its particular characteristics. To access this function you must first press the "EDIT" button to enter into the "EDIT MODE" and turn the FUNCTION SELECT knob to the right until ***DELAY*** appears on the display. The PARAMETER SELECT control will allow you to access each of the following Delay parameters: The PARAMETER ADJUST control allows you to adjust the selected parameter: DELAY I/O The DELAY I/O parameter determines whether the delay circuit is active or bypassed for the current preset. The MUTE TYPE parameter allows for muting the delay at its input (PRE), its output (POST) or BOTH. Muting the input (PRE) of the delay will not allow any signal to enter the delay section until the delay is switched in. When using a moderate amount of regeneration, switching out the delay with the input muted will allow you to generate a non-delayed signal which will play over the decaying regenerated signal which continues on after the delay is switched out. Muting the output (POST) of the delay will result in the delayed signal being immediately turned off when the delay is switched out. This means that delays and regeneration will not continue when the delay is switched out. If the output were not muted, signals that were input before the delay was switched out would be allowed to regenerate, even after switching out the delay. It is also possible to mute both the input and the output (BOTH) so that no signal enters or exits the Delay section until it is switched in. MUTE TYPE TIME1 The TIME1 parameter determines the multiplier by which a new delay time will be selected for Delay Time 1 when the Tap Delay feature of the Blue Thunder is used. (See Section 7 page 42: "Tap Delay" for more information on the Tap Delay feature. ) The TIME2 parameter determines the multiplier by which a new delay time will be selected for Delay Time 2 when the Tap Delay feature of the Blue Thunder is used. (See Section 7 page 42: "Tap Delay" for more information on the Tap Delay feature. ) The DELAY LEVEL parameter determines the overall level of the delayed signal at the output of the Blue Thunder. The D-MIX S1/S2 parameter defines the ratio of Source 1 signal to Source 2 signal to be input to the Delay section. Source 1 is the Voice 1 output from the previous effect in the signal chain (chorus, flanger, pitch shifter, etc. ), while Source 2 may be the Voice 2 output from the previous effect in the signal chain or the direct signal (selectable via the SOURCE 2 parameter). (Refer to the block diagram shown on page 13 for a visual representation of the input to the Delay section. ) TIME2 DELAY LVL D-MIX S1/S2 20 Functions and Parameter Descriptions SOURCE 2 This parameter is used to select whether the Source 2 input will be the VOICE 2 output from the previous effect in the signal chain or the DIRECT signal. [. . . ] The number on the right is the preset location that the preset will be stored into. RESTR Factory preset to be restored 1 TO 1 Preset location to store into Step 4 Turn the PRESET control to select the factory preset to be restored. RESTR 98 TO 1 Step 5 Turn the PARAMETER ADJUST control to select the preset location to store the restored preset into. RESTR 98 TO 98 52 Operating the Blue Thunder !!Pressing the STORE button at this time will overwrite the current preset with the displayed factory preset. Step 6 Press the STORE button to begin restoring the selected preset into the selected location. After the process is completed, the display should read "ERRORS 0". This represents the number of bytes that the Blue Thunder found did not initialize properly. [. . . ]
