Putting any amp before a Zaxcom receiver is not a great idea. The sensitivity of the receiver is optimum and the preamp will just bring up the signal and the noise together. It might be a benefit in a coal mine or Iowa corn field but not in actual use. Any amp used with our system must be very linear and have a lot of headroom (good IP3 rating) or intermodulation will affect the receiver where it now does not. Glenn Sanders President Zaxcom Inc.

The LTS uses a 3 pin lemo same as the TRX900LT. We have taken the power pin and converted it to a second mic input. The typical way to use the Lemo is to have it goto a "Y" cable and then to the 2 LAV mics. The LTS is compatable with all TRX900 2 wire microphones in mono mode. Glenn Sanders President Zaxcom Inc

I would not recommend LTS for a hop to camera. The TRX900AA with stereo adaptor is ideally suited with its external power connection, balanced line level input, IFB return and time code in/out. Glenn

The TRX900LTS two audio channel bodypack transmitter with recording and remote control will be featured at IBC. This is a two channel version of our new TRX900LT transmitter. It should open up many new possibilities for the use of wireless microphones in any application where a stereo image will help an audience feel they are in the middle of the action on screen. The unit features two microphone preamps with LAV power, two audio channel 100% digital RF transmission, Zax-net remote control and 2 channel recording with time code. The unit is a perfect match for the QRX100 2 channel receiver that can receive 4 channels of audio from two seperate TRX900LTS transmitters. TRX900LTS can be set to mono as well and is compatable with all Zaxcom UHF RF receivers. The unit will operate for up to 6 hours on a single AA lithium battery. The unit is now shipping.

This will be shown at IBC and delivered begining of October. It is the first ever battery powered wireless microphone transmitter with direct connection to an AES42 microphone. http://www.zaxcom.com/TRX942.htm

Here is an idea I had. With the IFB100 remtote you can put the TRX900 to sleep. If we tie the sleep mode into the record command on the Deva through Zax-net the transmitters should go about double the life they do now. Good rechargable A123 will do 5 hours. A TRX900AA and TRX900LT should do 12 hours. Added benefit is privacy for actors when not rolling. The wireless responce to the command is about 1/2 of one second so there should be no issues with responce time. Besides, that Sound Speed I hear can change to Zaxcom Speed. ;-) Glenn Sanders President Zaxcom Inc

You do not have to jam TC to go into record. With a TRX900LT formatted card in the transmitter it should go into record on its own. Glenn Sanders President Zaxcom Inc.

We still make the Mix 8 and Mix12. No plans to change that. Glenn

The QRX100 can receive mono or stereo transmitters for 1,2,3 or 4 channel receive. Glenn

The memory card is removed from the ZFR100 and connected to a card reader on a Mac or PC. Zaxconvert (Available on WWW.Zaxcom.com) is used to convert the files on the card to a Broadcast wav file with a time code stamp. This files can be dropped directly onto a protools time line or used in other audio edit systems. Glenn Sanders President Zaxcom Inc.

If 2 TRX900LT transmitters are used they are output on a single AES stream. Or as separate analog outs. Glenn

I am very happy to now be shipping TRX900LT and QRX100. These things always take longer than you hope they will. We are very focused on making the QRX100 the best ENG receiver ever built. I was quite surprised when Howy (Zaxcoms chief engineer) asked me if I wanted to program the QRX100 receiver by having the transmitter broadcast the software via the SD card in the transmitter. This feature allows any number of receivers to be updated at the same time and by the end user. This worked out great and was icing on the cake. The QRX100 RF section was a difficult design but in the end it came out great. With no intermodulation and the ability to receive 2 transmitters at once the QRX100 should be a hit with camera people due to the weight, size and power consumption for 4 channel receive capability. Current consumption worked out to about 250 ma at 12V for 4 channel receive operation. I think the AES output is also very cool. It eliminates any level mismatch to the camera and any possibility of ground loop problems common to analog camera inputs. AES output also lowers the power consumption by 30ma as we can turn off the analog outputs when AES is in use. Two cables are all that is needed to deliver 4 channels to camera. As Jack talked about the side mounted LEDs (Patented) are very neat. We made a matching camera holder so the LEDS will always be visible. Different colors indicate signal level and clipping and are visible in direct sunlight. The IFB and time code return channel option will be out soon and can installed in the QRX100 without a return trip to New Jersey. This is our 3rd generation receiver and I think our best yet.

While I don't think that one straight and one right angle will cause harm, I have never recommended it. I prefer 2 straight antennas in vertical orientation. I think this works best. Glenn

The TRX900LT does now ship with its wire clip. I am very happy with this transmitter. We did a lot of work on the power consumption in order to eliminate any heat output and to extend battery life. The unit will do 6 hours on a lithium battery while transmitting recording and receiving Zax-net. Nimh runtime is about 5 hours. The UHF audio tranmission range is equivalent to our current systems at about 500 feet under typical operating conditions. The Zax-net control range has been doubled to match the typical operating range. This was accomplished by adding a high gain 2.4 gig recieve antenna on the body pack. The thing that surprised me most was the response to the case. Actors prefer the nylon composite over our metal case transmitters. The very light weight at about 2 oz and rounded corners may also be a factor. Glenn

This is an artifact of the power saver mode. It is nothing to be concerned about. Glenn

Zaxcom has released a series of instructional videos. They can be found at the following link. http://www.youtube.com/zaxcom1#p/u Glenn

Hi Damian, It sounds like our ERX1TCD time code/audio receiver and IFB100 transmitter would be a perfect solution. The ERX1TCD receiver will output both time code and received audio at the right level for the camera giving you both time code and audio with the picture. Please have a look at the Zaxcom web site for details. http://www.zaxcom.com/erx.htm Glenn Sanders President Zaxcom Inc.

Zaxcom upgrades Zax-Net time code capability. The Zax-Net system of time code, IFB audio, wireless remote control and metadata distribution via 2.4 GHz RF signal has had its time code capability and accuracy upgraded. With the ERX1TCD IFB audio/time code receiver the Zax-net system can deliver time code anywhere on the production set with an accuracy of +/- .01 frames with no drift. The ERX1TCD can now also delay or advance its time code output up to 10 frames to accommodate the picture delay that often takes place when video is converted to a different format. The ERX1TCD can also delay its IFB audio output as well so that both time code and audio will match picture delay in any situation. Use of the Zax-Net system eliminates the need to periodically jam code to every device on set. It also eliminates the time code drift common to all crystal based time code generators. Time code is always locked to a common generator via RF signal. The ERX1TCD can output any time code rate allowing for generation of different rates from a master generator. The Zax-net upgrade is available free of charge to all Zax-Net users. Glenn

Hi Jan, This is not the model of amp we reccomend but L-Com is the right company. I am out of the office till monday so I do not have the model number with me. Colleen at Zaxcom can give you the correct model number. Glenn

Yes a scope is what you need. You should see a square wave at about 4800 bits per second. An AC voltmeter should read about 2-3 volts pp if you cant find a scope. Glenn

Fusion and Deva time code outs are about 2V-3V PP. Unless the output is damaged, it should feed about anything. Glenn

Hi Cloud You may not have the IFB option in the TRX900. Since you can receive OK on the ERX. We will need to check this. Please Email me your TRX900AA serial number privately and we will sort this out for you. Best Wishes Glenn

When using the QRX with a TRX900 AA and an STA adaptor can you get both IFB return from the camera and Time Code return simultaneously - or is it one or the other? You get both coming back but only one is output to the connector. The return time code is used to control the recorder in the TRX900AA. The output jack is switchable between IFB audio return and time code out. Our ERX1TCD will output both at the same time. Glenn Jack

I am going to check with Howy on this as it could go either way. I would like to see the gain control function work for all transmitters with just one option board but there may be a technical reason that we may need one in each receiver. Glenn

Hi Robert The RX900s and QRX100 have the same audio quality. Definitely use the QRX100 in a bag or cart. The form factor is designed for a camera but the QRX100 will go anywhere. I would look at the TRX992 for Boom rather than the TRX900AA. The TRX992 7 Hour battery life, true diversity IFB RX, 48V power, balanced XLR input and powerful headphone amp/ monitor mixer make it the TRX992 the best choice. If you have your heart set on the TRX900AA look at a neat 48V boom adaptor made by our French dealer Arietec. The QRX100 with option board will be able to control the gain of the TRX900 as well as broadcast IFB audio and time code. The RX900 will receive a single mono or stereo transmitter. The QRX100 will receive two mono or stereo transmitters for 2,3, and 4 channel audio receive combinations. As the QRX100, ERX1, TRX900LT and Zaxnet are very new and allow for functionality that has not been seen before I invite questions to be asked here on uses of the new system. I will be on the group every day to answer. Best Wishes Glenn Sanders President Zaxcom Inc.
