FAQ

RANG III

 

Q. How many loops can I play at once?
A. The Boomerang III can play up to 4 loops at once ( 3 right out of the box), either synced or completely independent of each other.

 

Q. Can I loop more than 1 section of music (i.e. verse, chorus, bridge)?
A. Yes, set the PlayStyle mode to “Serial/Serial Sync” and all your loops play after one another in any order you'd like. Boomerang has simplified the process by allowing the player to press one foot switch to simultaneously start a new loop while ending the previous loop track.

 

Q.  Does the Boomerang III have a quantization feature?
A.  Yes, if you start your looping performance with “Master Loop 3”, all additional loop tracks will sync to the timing of “Master Loop 3”. They can follow the exact length of “Master Loop 3” or be any multiple of it. (i.e. twice as long, three times as long, four times as long etc)

 

Q.  What instruments work with this looper?
A.  Anything that can send its audio out through a ¼ cable. Here are some examples (electric guitar, acoustic electric guitar, keyboards and synths, electric violin, vocal processors, mulit-fx processors, drum machines/samplers, recording interfaces and more.)

 

Q. Can I sync the Rang III to an external MIDI tempo from another device? 
A. Yes, MIDI clock will be received via the MIDI in port (pedal link in) on the back of the Rang III. When the Rang III is synced to an external clock/tempo source, the “Sync” light will flash in tempo. The following features sync to incoming tempo. 1) loop start and stop, 2) PlayStopAll, 3) Fade Time.

 

Q. What MIDI commands does the Rang III respond to? 
A. The Rang III only responds to MIDI commands from the Side Car controller and MIDI clock data. You can not change or customize the way Boomerang III responds to MIDI.

 

Q. Are the audio jacks balanced or unbalanced?
A. Unbalanced.

 

Q. What features can I control with an Expression Pedal?
A. Volume level of your loops or the decay rate.

  

Q. Recording time?
A. Sampling at 48KHz, the III records for 8 minutes 46 seconds in mono. Sampling at 24KHz, the time is 17 minutes 32 seconds. Record with 24KHz sampling and Octave active (half-speed), and recording time is over 35 minutes. Stereo recording cuts all times in half.

 

Q. Will the Rang™ III improve my social life?
A. We feel confident that you'll make a lot more friends. 

 

Q. Why, when I stack a new part, does my original part disappear?
A. This happens when the “Decay” setting is higher than “0”

 

Q. How do I save my settings so that they are the same after power cycling my III? 
A. Press and Hold the “Bonus Assign Mode” button until the “4” LED flashes green, then press and hold it a second time until the LED stops flashing.

 

Q. What settings can I save on the Boomerang III? 
A. All volume settings, decay time, fade time, play style mode, and bonus button settings.

 

Q. What volume setting is unity gain? 
A. Unity gain is 7 on all volume knobs

 

Q. How do I update the firmware on my old Boomerang Phrase III Sampler?
A. That info is listed on the FIRMWARE section of this site. 

 

Q. How do I know which Firmware is installed on my Boomerang III
A. That info is listed on the FIRMWARE section of this site.  

 

Q. Compact flash cards?
A. There is no card slot for removable media.


SIDE CAR

 

Q. Does the Side Car™ Controller require an additional power supply?
A. No. A "power splitter" cable is included so the SC can share the III's 500mA power supply.



Q. How does the Side Car™ Controller connect to the III?
A. With a 3' standard MIDI cable, which is included. 

 

Q. Can I use the Side Car™ and send MIDI clock to the RangIII™?
A. Yes, the Side Car™' can go between the device sending MIDI clock and the III. The MIDI clock will pass through the Side Car™ and then into the III's MIDI in port. 

 

 POWER SUPPLY 

 

 

Q.  Can I use the Boomerang power supply outside of the United States?
A.   Yes, but only if you have one of our international power supplies.  If you buy a Phrase Sampler from us we will send the appropriate power supply for the region we are shipping it to.  WARNING - it is not safe for the pedal to use a wall adaptor only intended for 120volts in a 220volts or higher power outlet.   If you are unsure which power supply you have please contact Boomerang Support before using it

 

Q.  What are the power requirements for the Rang™ III, Side Car™ controller and Chorus*Delay?
A.  The E-Series pedals are very forgiving and will work with many types of power supplies. Most supplies with the one of the following output specifications will work: 

Always OK
1) 9VAC, 500 to 1500mA
2) 9VDC positive tip, 500 to 1000mA

Usually OK *
3) 9VDC or 12VDC negative tip, 500 to 1000mA

* If your DC supply is ISOLATED the polarity of the plug doesn't matter (can be either + centered or - centered). If the supply is not isolated (either directly or through other pedals which may be connecting one side of the supply to the audio common) you must use a + center plug. 
* In order to provide for some flexibility in power sources for the E-Series pedals, the power jack is NOT connected directly to the audio signal ground but is routed through a full-wave bridge rectifier prior to a connection to all internal circuitry. This approach allows for the use of AC power sources and auto-sensing of DC power sources but mandates that the power source MUST BE FULLY ISOLATED from any direct or indirect path to the ground side of any audio/control inputs or outputs connected to the pedal. A direct path could be created by using a power supply that uses a 3-wire mains plug and has one side of the output connected to the mains ground (rare). An indirect connection can occur when a single power source is 'daisy chained' between several pedals and one or more of the additional pedals has its audio ground connected directly to one side of its power jack (common). In this case one wire in the power cable attached to the E-Series pedal is indirectly connected to the audio signal ground and this violates the full isolation requirement. This situation cannot only create a 'ground loop' hum problem but could also severely damage the power supply and/or the E-Series pedals. In general it is recommended that the E-Series pedals always be powered with the power adapter supplied with each unit. Boomerang Looper LLC cannot be held responsible for any damages which result from the use of any power source other than the one supplied with each unit. 

Q.  What are the power requirements for the Original and Rang™ Plus loopers?
A.  Our first two loopers can only operate with AC power. A compatible supply must have these output specs: 9-10VAC, 500-1000mA. A standard stomp box 9VDC supply will NOT work with the Rang™ Plus or Original. 

Q.  What do the different output specifications on power supplies mean?
A.  All power supplies that plug into the wall are called AC adapters because the wall power is AC (Alternating Current), but they can OUTPUT either AC or DC (Direct Current). There are NO polarity issues with a power supply that outputs AC; this only applies to power supplies that output DC. 

Voltage rating of a power supply
Stated in V (volts), this is the critical number. Running a 9V device on an 18V power supply will make it run hot and cause damage. A 9V device won't run on a 6V power supply. 

Amperage rating of a power supply
Stated in mA (milliamperes), this is the current rating and represents a maximum capability. Unlike the voltage, it is not a constant value. The power supply will deliver only what the device asks for. If a pedal wants 600mA and the supply can provide only 300mA, then it won't work though no damage will occur. On the other hand a pedal needing 400mA will work OK with a 750mA supply. 

 

 

TRUE BYPASS FACTS 

 

The Case Against True Bypass by  Pete Cornish (© Pete Cornish 2003)   http://www.petecornish.co.uk 

The "true bypass" function, which is promoted by some, can create dreadful problems with a system that uses many pedals. Take for instance a 15 ft guitar cable linked to ten pedals, each linked by a 2 ft cable, and then onto the amp by a 30 ft cable. If all pedals have "true bypass", and are off, then the total cable length hanging on the guitar output will be 63 ft. This will cause a huge loss of tone and signal level particularly if the guitar is a vintage type with low output and high impedance. The amp volume is then turned up and the treble control increased to compensate for the losses. The inherent background noise now increases by the amount of the gain and treble increase and is usually, in my experience, too bad for serious work. If one of the pedals is now switched on, then it's (hopefully) high input impedance (and usually low output impedance) will buffer all the output cables from the guitar and the signal level will rise due to the removal of some of the load on the pickups (i.e.: 17 ft instead of 63 ft of cable). The treble will rise and the tone and volume will not be as before. If that pedal was say a chorus or delay, devices which are usually unity gain, then your overall signal level and tone will vary each time an effect is added...not a very good idea. 

Some pedals have an input impedance which is far from high in real terms; the input impedance of the vast majority of amps is 1 Megohm (one million ohms) and in my experience there are few effects pedals that have the same input impedance. A load on the guitar of less than 1 Megohm will reduce the volume and high frequency content of the pickup signal thus giving rise to complaints that "this pedal looses tone/volume" etc. Many effects I have tested have an input impedance of less than 100 Kilohms (ie: only one tenth of the amp input impedance) and cause serious signal losses in the effects chain. 

My system, which I devised in the early 70's, is to feed the guitar into a fixed high impedance load, which is identical to the amp input, and then distribute the signal to the various effects and amps by low impedance buffered feeds. This gives a constant signal level and tonal characteristics, which do not change at all when effects are added. The proof that this works are in the recordings of our clients: Roxy Music; The Police; Queen; Pink Floyd; Bryan Adams; Lou Reed; Dire Straits; Paul McCartney; Sting; Jimmy Page; Judas Priest; Black Sabbath.... 

So the answer to your question re "true bypass" is no, I do not use this system in my Effects Boards/Racks as it can seriously degrade your sound. All my current effects pedals (excluding Vintage Series) which are derived from our large systems have, as the main input stage, a fiendishly clever pre amp that has the same characteristics as the input of a tube amp (1 Megohm/20pF), a highly efficient filter to eliminate the possibility of radio breakthrough and a low output impedance so that any following pedals/ cables etc. will not impose a load on the guitar signal. This pre amp is fitted to all our large stage systems and has always met with huge approval; not only from the guitarist but also the PA operator who is so happy to have constant level and tone presented to his mixing board. I go further with large systems and provide several inputs, each with the isolating pre amp and a gain compensation pre amp so that many different guitars can be level matched into the system. In addition a 20 segment PPM type display provides visual indication of signal level in our Effects Boards and Rack Systems.
