How long is the warranty?
In the USA, the warranty is one (1) year from the date of purchase from an authorized Rane dealer. Here are the details.
Where can I buy model ###? Can I buy direct?
Rane only sells through our dealer network. Here is our dealer locator, and our regional representatives or Rane can recommend a dealer. The only items available direct are accessories.
Where can I get ### software?
Every unit's product page has links to current and previous software it uses. For discontinued units, check here.
My faders/slide pots are getting noisy / sticky / hard to move. What can I do?
Perhaps your Crossfader doesn't need replacing, it just needs a good cleaning. Here are the instructions. If you really want a new one, you can order one here.
I need to modify a unit. Who do I talk to about this? And / or I have a modified unit and need to get it serviced, where can I take it?
Modifications are against company policy, with very few exceptions. The ones we authorize and condone, as well as support are listed in the respective manuals or on our website. We do not support any automotive applications nor provide information to the do-it-yourself crowd for reasons of liability. Units which have been previously modified whether correctly or not, can be sent to the factory and returned to stock condition. We do not preserve unauthorized modifications or restore malfunctioning ones. This type of work needs to be sent to a custom shop or specialty technician. We do not have lists of this type of personnel nor do we support work in this area, (i.e. if it isn't stock, you're going to have a hard time getting support for the unit, unless you want it reverted back to original factory condition).
I need a schematic and / or manual for a unit, but don't see it on your website. What can I do?
All products have PDFs of data sheets and manuals under the "Data Sheet and Manual" tab on each product page. If a schematic is available (analog products only) then the schematic is also in this location. Previous versions and discontinued units are listed in Discontinued Products. Every letter in the model designation makes a difference, so be sure to view the same documentation for your particular unit, (i.e. don't use an MP 22z manual if you have an MP 22). The relevant documents are: Data Sheets for specifications and block diagrams, Manuals for operational details and instructions, and Schematics for internal wiring diagrams and circuitry references. Schematics for some units contain proprietary information which may not be completely divulged for confidentiality reasons. If you don't find it in any of these places, call us.
My mixer has an external power supply and I'm hearing hum.
Older units with external power supplies (the Rane RS 1) don't get grounded through the power cord. Since no third prong exists on the AC power plug, you must connect a separate wire to the small silver screw on the rear of the unit, and attach the other end of this wire to a good known earth ground, or to an amplifier that has a 3-prong grounded plug. Some examples: a steel AC conduit, cold water pipe, steel building girder, or the center screw on an outlet. Painted rack rails don't work, nor does rusty metal. Our Technical Support Department receives calls about units damaged because they weren't properly grounded. Don't take chances, follow the directions completely. This article explains remote supplies.
I need a part (fader, power supply, power cord, knob, etc.) for my unit, but I can't get the dealer to order it. What do I do?
Customers can order parts directly from the factory between 8:30 and 5 Pacific time, weekdays. Alternately you can email our parts department. All orders or inquiries must have the serial number. Parts orders can only be taken for customers in the U.S. International correspondence should be directed to your International Distributor. Tip: When ordering parts, describe the piece exactly as it is on the product. (Example: Master Slide Pot; PCB Mount Headphone Jack; Phono 1 RCA Jacks.)
I am trying to find an RS 1 external power supply for an older Rane unit.
Due to new power efficiency regulations our supplier is no longer able to manufacture RS 1 power supplies. Meeting the new regulatory requirements would require a prohibitively expensive redesign for an obsolete part. Rane stopped manufacturing products requiring RS 1 power supplies in 2009. Since that time, for over five years, we have been able to supply replacement units; unfortunately that is no longer possible. We sincerely regret this unavoidable action and the difficulties it makes for our customers.
I bought a unit, but it doesn't have a serial number. Can send it in for warranty service, i.e., will it be covered?
We can't cover units that have the serial number removed, as there isn't any way to determine its revision or age.
Where do I find the serial number on my unit? What does it look like?
Rane product serial numbers have taken on various forms over the 20 plus years we have been manufacturing units. In the very early days, units contained part of the model number within the serial number, and all of this type start at 1002. A period separates the model letters from the serial numerals, (Examples: AC3.2345 is an AC 23 from 1986, MP.1234 is an MP 24 from 1986 and ME.3333 is an ME 15 from 1987) These are found on a vinyl silver sticker, with black print about 1 1/2" wide and 3/8" tall. There may be as many as five digits after the model designation. The date code is a separate similar tag but only 1/2" wide by 3/16" tall. Numbering represents the manufacturing quarter of the year the piece was made, (Examples: 1-88 is January, February or March of 1988, 4-90 is October, November or December of 1990). Starting January of 1999, we changed to month codes. (Examples: Later smaller sticker 2-99 means February 1999 and 9-99, indicates September 1999). Silver tags were installed on either rear or side panels as matched pairs. On March 15, 1994 we changed to nonsensical serial numbers, dropping the model number from the nomenclature. The first of this type is serial 30001, (an AD 22 for those interested --- having a date code of 1-94). Finally, in October of 1999, we changed to a white thermal paper bar code sticker, listing both serial number and date code together. Isn't togetherness better? These are mounted on the side of the unit. Dimensions are 2 1/2" high by 1 1/2" wide. Each has (21) before the eight digit serial number (Example: (21) 00333333 [an ME 60 from August 2001]). Serial numbers are the bottom row of digits on the bar code decal. So for all those looking at used gear, be aware of what the date code can tell you. Also be specific and complete with regard to model numbers: an MP 24 is significantly different from an MP 24z. Likewise an AD 22 and AD 22d share very little in common with regard to circuitry. Do not tear off or alter serial number tags: it voids your warranty. To the purchaser of used gear we say: "caveat emptor" (let the buyer beware).
Can I use more than one set of outputs on my unit? How much signal loss will occur if I do?
When multiple outputs are used, or a Y-cord is connected to drive parallel inputs, in the majority of situations no signal loss will occur. For the technically inquisitive, a minimum load impedance of 10 times the source is recommended. Most Rane outputs are 100 ohms per leg balanced, so net impedance limit is 1,000 ohms (or 1K). You may safely use all outputs at once, with the only concern being mixed-mode wiring with balanced and unbalanced combined can contribute to ground loops (i.e. hum in the system).
I saw a Rane unit recently with rubber knobs and different cosmetics. Can I change the knobs on my older unit to the new style?
Unfortunately not. When we updated the look of Rane products we changed to a different style knob (called a Flexi-fit) which will not fit the older units. Controls and artwork have changed and evolved. Like most anything change eventually happens and we thought it was time for a new look. Sorry to those who are confused or inconvenienced, but units with older knobs are still just as good as their newer counterparts.
I'm buying a unit in the U.S.A. take back home overseas and need to get it in 230 volt version, how do I do this?
This type of purchase is called a gray market transaction. Warranty on Rane products only applies in the country of purchase and U.S. models only ship with 120 VAC power supplies. Units taken out of the U.S. do not have warranties in the destination country and some distributors may not offer any parts or service support. This is their option. Rane discourages gray market purchases and highly recommends that customers buy Rane items in their home territory, due to a multitude of reasons. Be forewarned that saving a few bucks on the purchase price is easily wasted the first time service is needed. Certain Rane units are Factory Service Only and since the distributor is the only one who can repair them (or send them back to the factory for repairs) gray market units come with substantial limitations. Support your local agents; buy locally.
What is the maximum BTU / Hour produced by model [ insert model here ]?
To calculate maximum BTU / Hour, multiply the input power rating in watts on the rear panel of the unit (or on the external power supply, [i.e RS 1]) by 3.41. Example: RPM 88 is rated at 55 watts AC, therefore we expect a maximum of 187.55 BTU / Hour.
All Rane units meet these specifications.
