Sennheiser ASP2 Splitters - How many mics can I realisticly run?

[gregog]

Hi All,

Firstly, I'm not a noise boy, so please be gentle. The venue I am currently in has 7 operational mics. All sennheiser ew100/300/500 G1, G2 and G3. They are currently all being fed by two ASP2 splitters that I fitted last year. (With UHF Wideband Directional Antenna -Passive Sennheiser and sennheiser Antennae Head Amplifier with a 10db gain).

My question is basically, have many more mics can I run using these splitters, or would I need to purchase more splitters or indeed something like this Sennheiser ASP-212 (ASP21) 2 x 1:2 Passive Antennae Splitter?

I have just purchased 3 new 300 G3's as the need to have more available on site is becoming a nescessity. I have two antennas feeding the current ASp2's, antenna A and B. What do I need to buy/ do, to split the signal to allow for these new receivers to be rack mounted alongside the rest using the splitter to keep things tidy?

I know I could split the signal before it reachers the splitter, but would this reduce quality?

Or how can I link another ASP2 splitter into the mix?

If someone could please advise me on how best to do this it would be grealty appreciated... Otherwise I'll have to phone Tom at Orbital and sound stupid!! haha!

 

Many thanks and I hope it all makes sense,

Steve

*Shameless Bump* Anyone? Does what I've asked make sense... A lot of people looking but no answers. Have I been particularly unclear??

How many outputs does the splitter have? I think it'll be four pairs, which means you can connect four receivers to it. I think you can also feed antenna A in to one splitter and split it eight ways and do likewise with antenna B and another splitter so you can feed eight complete receivers that way. Is there a link on output on those splitters?

 

Does all of the antenna kit cover the whole of the frequency range that you want to use? Assuming that you're up in ch.69 territory, you won't be able to use much of it after 2012 anyway so buying anything more in that band now wouldn't be very worthwhile.

Am I right in thinking that the ASP2 does power distribution to all of the receivers also?

If im thinking about the right splitter you'll get 4 receivers on each of them with power and RF,

so you'll wind up with 8 receivers on an A/B antenna split.

All of the A going to one ASP and all of the B going to other.

 

hope this helps

Hi Mike,

Thanks for the post. Yes, they do indeed have the power for the units too. What I'm meaning is that I already have 7 receivers and mics running already from two ASP2 splitters. I have just bought some more microphones and want to add them in. I can only add one more on the splitters I already have, making 8 mics run off Antenna A and B through the two existing splitters.

 

What I want to know is, how can I split the antenna signals (through another splitter or something I don't know?) in order to run my two extra radio mics without having them seperate from the rack?

So essentially, how can I run 12 radio mics in a rack using splitters, being fed from only 2 antenna inputs, currently running through two ASP splitters. I'm pretty sure I cant using the stuff I have already. So what do I need to buy/ do to run 12 radio mics from the two antenna signals??

 

Many thanks,

S

One way to do it.

 

Suggest you look at an AS3000 Active Splitter - Unity Gain across the device - use this to feed 3 ASP2's for your 12 receivers, I.e connect A & B ins of ASP2 to A's and B's out of AS3000, connect your active antennas to the inputs of AS3000

 

However without an input filter you are adding another wide-band amplifier into the RF chain. Why this can be a bad idea has been discussed on Blue Room before.

 

As noted above what frequencies are the units operating on ?

Many thanks for everyones help in this field. Got it sorted now

 

Thanks again :)

Got it sorted now

Any chance of revealing what you ended up getting?

Interesting one you have a mix of G1 G2 and G3 my concerns would be that the G3's are powered via the antenna BNC Wouldn't this cause a problem when using the ASP 2 which has power leads that go to the receivers. I have built 8 x G3 receivers into a rack using 2 x ASA1 spitters two NT1 PSU's and the whole lot worked using just the BNC cable to power the receivers. My point is wouldn't you get the voltage going back into your ASP2 when using the G3 stuff from the antenna BNC? This could cause problems. Also I assume that the G1 and G2 stuff is in the 790 Mhz to the 865 MHz banding's? If so this lot you maybe able to claim for funding to get new stuff. I would suggest contacting Sennheiser technical department on 01494551551 just ask for the technical department or press the relevant buttons your phone. You can also contact me sales@ultimateproaudio.co.uk with regard to Sennheiser gear I do a lot of leg work for our customers with regard to supplying them with the right gear lighting or audio. Also if you are after a quote for radio mics splitters Or anything else let me know I can supply it a great price.

Can anyone confirm for certain that the Sennheiser ASP2 splitter is not compatible with G3 kit?

 

If so, why on earth did Sennheiser make it incompatible? Daylight robbery?
