Lectro Venue System

Glen-

For goodness sakes, man. Help me out here. Did they work well? Did they
have appropriate range? Did the sound good? What did you love? What did
you hate? Did you try them with any analog xmitters? Did you set the system
up through the front LCD screen? Or use LecNet and a laptop?

Specs say 900mA for a rack of six. Pretty darn low.

The 900mA spec is at 11 Volts. At higher voltages such as 14.4 Volts,
the current is proportionaly less. At 14 Volts the drain is 715 mA.
The way to think of it is that the system when fully loaded pulls 10
Watts. Just divide the input voltage into 10 and the result is
fractional Amps of drain. Times 1000 is mA.

The main board pulls very close to 4 Watts and each model is about 1
Watt. Main board plus 6 modules is 10 Watts. Main board plus two
modules is 6 Watts.

For those who just want the simple numbers, the main board is 333 mA
at 12 Volts and each module adds 83 mA at 12 Volts.

Doug,

I was very happy with the Venue and believe it is outstanding for sound cart
use.

To be able to fit 6 receivers in a single rack space, and be able to scan a
single, small, LCD screen to get information on all 6 receivers was more
than nice, it was beneficial on a practical level.

I was interested to see how using the LCD screen compared with using the USB
port with a notebook computer. I was surprised at how useful the built-in
LCD screen was, and I was convinced that the computer certainly was not
necessary to use the Venue. However, using a computer made it even better
and allows more information to be seen in a single screen. The computer also
makes changes in settings faster. Keep in mind, however, that the built-in
LCD screen, alone, is a big step forward compared to the alternative of 6
individual receivers like we have been using before the Venue. But whenever
practical, I would have the computer attached to the Venue. Since notebook
computers are becoming more and more common place on a cart anyway, why not
use it to enhance your wireless rig too?

The audio quality is the same as the stand-alone Lectro 400 series
receivers, which is quite high compared to the traditional full-analog
systems. I used one channel of the Venue for wireless boom (using a
Sennheiser MKH-60, and Sanken CS-1) which worked very well in a wide range
of dynamic scenarios (low level, high level, both in a single sentence...).

Logically, all of these features should make the system more valuable than
the traditional setup, but the fact that it is vastly lower in price...
well... you just can't ignore those kinds of numbers.

Once again, solid numbers and straight talk from Larry. Much thanks.

Yep. Thanks Larry, no clouds.

What might be relevant to mention is that the receivers in the Venue
are single one's.
A normal 400 has 2 receivers in it ( Diversity ) so theoretically 1
venue unit has 3 400 units, only the big advantage could be that you
can switch/decide yourself if you like to use a single unit as a
single TX, or 2 units as one Diversity Tx.

Now, i have a 400, but i would not dare to use it on a boom, without
the diversity. ( or i must be 10 meters from the set max ).

I also got the strong impression that these ( single ) units where
made for theatre, or fixed controlled setups. But if it works it
works..

Larry please, can you explain the difference between the VRS and VRT
module types please? Or are just operating modes?
Are both types available yet?
Wich of the two is equivalent to a current UCR411?
Can both types be mixed in the same Venue rack?
Thanks,
Fernando

Aha, so i was wrong :-) ( Good to know ! )

Me to, i got that idea from a talk at a trade show, but it';s always
good to stand corrected.
Now, one more important figure, what's the
street price of 1 full rack ?

The Venue system offers three relevant choices for diversity reception:



1) "Antenna" or "Phase" diversity. This method is what is
used by all Lectrosonics UCR (compact portable) UHF receivers. With this
method, when the system detects that the signal is being receive by both
antennas is being degraded because of out of phase signal, the B antenna is
reversed to maximize the combined signal strength.


2) Receiver Diversity (often mis-nicknamed "True
Diversity"). This method uses two receiver s for a single transmitter,
favoring the strongest signal of the two receivers. The Venue can do this,
but because it uses two modules per channel, when this mode is selected the
Venue system is limited to 3 channels per rack module. Rarely worth it in my
opinion.


3) Frequency Diversity. This is arguably the most reliable
of all diversity options, but it requires two transmitters and two
receivers. With this method, the talent wears two transmitters (on different
frequencies) with the microphones directly next to each other to minimize
"comb phasing" effect. The Venue system then blends the two receivers,
favoring the receiver with the strongest signal. If one transmitter should
drop out, the Venue would totally switch to the remaining channel.

The only thing I would add to Glen's post is that in frequency
diversity each receiver is still doing its phase diversity routine in
each individual receiver. Since each antenna is picking up two
different frequency RF signals and each transmitter is uncorrelated at
each antenna, it really is as if you had a 4 way "quadversity" system.
The levels of the two transmitters and the mics can be matched at the
receiver with a menu selection that inverts one signal letting you
adjust for a null. The transmitters should still be set for similar
levels and the mics must be very close together. One mic could be
split and run to each transmitter which would eliminate one variable.

Though I think it's cuter than Hell, I don't see it as a biggie.
