Frequently Asked Questions

Can I use more than one set of outputs on my unit? How much signal loss will occur if I do?

Technical Support
When multiple outputs are used, or a Y-cord is connected to drive parallel inputs, under the vast 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 unbalance combined can contribute to ground loops (i.e.

When I use the 1/4" balanced outputs, no signal comes out, but the RCA jacks work fine. Why?

Technical Support
Typically this is caused by incorrect adapters being used. There is a 1/4" to RCA adapter available which looks balanced at the 1/4" end, but it's not. There is no such thing as a balanced 1/4" to RCA adapter. Those which have two insulators (look for two black stripes) and resemble a common stereo headphone plug are just that: a stereo plug. It's not balanced and won't work in the 1/4" output jacks. The correct adapter is an unbalanced (i.e. "mono") 1/4" plug to RCA jack.

How Does Hearing Loss Occur?

OTG, Inc. - Specializing in Onsite Pulmonary Testing, Mobile...
Sound enters your ears in sound waves. These sound waves hit your eardrum and are converted to pressure changes in the inner ear. This causes special nerves to impulse, which are read by your brain as sound. When these nerves are exposed to a surplus of pressure changes, they may become damaged. You may have noticed that if you listen to loud music for several hours that your ears "ring." This is a Temporary Threshold Shift, or a temporary reduction in hearing.

How do I get signal out of the Main Outputs?

Mackie - CFX.mkII Series FAQ
Unlike some other Mackie mixers, the CFX.mkII mixers do not automatically pass signal from the channels to the main outputs. There are also no L-R assign buttons on the channels to assign them directly to the main Left/Right bus. Therefore, you must send channels to the Subgroups and then route the Subgroups to the Main Outs. The most straightforward way to achieve this is to press the 1-2 assign buttons on all of the channels; these buttons are located next to each of the channel faders.

Can I use both the XLR and 1/4" outputs at the same time?

Technical Support
Yes. Both sets of output connections may be used simultaneously. However only one input may be used at a time. Also remember if you run unbalanced 1/4" with a balanced XLR you may have ground loop problems.

Are there any outputs from the QwikData unit?

FAQ
Yes. There are two outputs that can be used to control lights, alarms or relays. These outputs can be programmed to turn on and off based on the values of the signals on any two of the input channels.

When does the signal actually occur ?

Q & A
Signal always occurs on day 0. The search space extends from current day (Day 0) to the number of days (or bars) back as set in the program. Within that search space, all OHLC quotes will be considered during the optimization process. If you choose to use the Day of Week selection feature, you will see the Day 0 or signal day, which is the current day if you trade on current close, or the day before entry if you trade on next open.

If I use the RCA inputs with the XLR outputs does this make my system balanced?

Technical Support
Any unbalanced wiring in your system will unbalance the entire system, so you should try to run balanced everywhere possible. All subsequent wiring from the ME 60 downstream will be balanced in this scenario. We suggest reading Sound System Interconnection. If you feed a balanced input from an unbalanced output you can still retain the benefits of balanced wiring, but you have to modify your cables.

How can I resolve issues with signal loss?

FAQs | Xwire
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with the router and your wireless PC in the same room and move it away in small increments to determine the maximum range in your environment.

scheduled backup is set to occur (I.e if I use a 56k modem)?

Online Data Backup - Frequently Asked Questions
If you are on a (56k) dial up modem, and you are not connected at the scheduled time of backup, as long as your computer is switched on, Depositit will automatically activate your modem and dial up to make an Internet connection. Once connected Depositit will upload any new or changed data and then close down your connection when finished. If you subscribe to ADSL/Broadband and have closed down the connection. Depositit will upload your data the next time you connect.

When Zone 1 of the CP 64 is in Mono mode, which outputs LEFT or RIGHT should I use?

Technical Support
Either set will provide a summed LEFT plus RIGHT mono signal. You can use both LEFT and RIGHT outputs simultaneously when needed, (like when you want to run two channels on a power amplifier without connecting a Y-cord.) Yes. The internal Program Priority Release Time control, located near the Line 2 and Line 3 RCA input connectors, can be rotated to change the interval from five to twenty seconds. Clockwise rotation increases the release time interval.

What kind of inputs and outputs can I use?

Mackie - FAQ Hard Disk Recorders
The HDR24/96 uses a three-slot card cage for all inputs and outputs. Each slot supports a single card for eight channels of I/O, giving you a total of 24 channels I/O simultaneously. Four different tape I/O cards are available: the AIO•8 (analog format, +4dBu signals), the DIO•8 (24 bit ADAT optical & Tascam TDIF formats), the OPT•8 (24 bit ADAT optical format only) and the PDI•8 (AES/EBU format).

How do I set the unit to operate in Binary mode?

Technical Support
Simply hardwire connect the Memory Recall Port (MRP) terminals numbered 5, 6 and 8 to the COM terminal. This will enable the unit to accept binary memory recall input and yield 24 memories.

Which remotes can I use with this unit and are they still available?

Technical Support
No, both the Paging Assign Remote CP R1 and the Source / Level Remote CP R2 are discontinued and remaining stock has been sold. These are the only remotes that are compatible with the discontinued CP 62. Parts to repair existing remotes can be ordered through Customer Service. IMPORTANT NOTE: The CP 62 is the only Rane remote powered model produced which must use the RS 2 power supply.

Can I use a different microphone with the unit?

Technical Support
The MIC 1 is the only microphone we certify to operate correctly with the RA 27, RE 14 / 27 models. Using any other device may damage the analyzer, measuring device or both. The one known measurement microphone witnessed compatible with the RA / RE series retails for over $ 500.oo, thus it is wiser to purchase an original Rane microphone.

When do they occur?

Varicose Veins - Frequently Asked Questions
Varicose veins are most commonly found on the legs of women and men who spend a lot of time on their feet. Birth control pills, hormone therapy, obesity, weight fluctuation, and constipation can also add to the development of varicose veins.

How can I set marker in signal?

SIGVIEW signal analyzer - FAQ
Markers in Sigview are closely related with Instruments. Most Instrument can place corresponding marker in a signal. For example, if you use Maximum instrument to show you the maximal signal value, marker will be displayed on the signal graph maximal value location. You can turn marker on/off or set its parameters by editing instrument properties. If you want simply to set marker on some specific location in the signal, please use "Marker at..

How can I use Matlab's import feature to read signal files?

Frequently Asked Questions about PhysioNet
You can't in general, because Matlab doesn't know how to figure out which of the many supported formats is used in any given signal file, because it can't understand the most commonly used formats in any case, and because (in many cases) signal files are orders of magnitude larger than any matrix that Matlab can handle. See How can I read signal files? for a variety of ways to read signal files from Matlab without using its import feature.

How can I use Excel's import feature to read signal files?

Frequently Asked Questions about PhysioNet
You can't, because Excel doesn't know how to figure out which of the many supported formats is used in any given signal file, because it can't understand any of those formats in any case, and because signal files are almost always orders of magnitude larger than any spreadsheet that Excel can handle. Spreadsheets are not suitable for studying, visualizing, or analyzing digitized signals; many better tools are freely available in PhysioToolkit.
