1788 REMOTE CONTROLLED PREAMPS ON TOUR WITH PEARL JAM
The American leg of the Pearl Jam world tour kicked off on August 3
with a major change to its recording and PA rig. Five Model 1788
remote controlled 8 channel preamps replaced the traditional system
of connecting the microphone into a transformer splitter, down long
cable runs and into the preamps in the consoles.
The 1788 has two separate analog outputs and three separate digital
outputs for each channel. The main output is fed to the FOH console.
The auxiliary output is fed to the monitor console. And the AES3 output
is fed directly to a Sony PCM and then on to a Pro Tools system. The
1788's are installed up on stage, thus eliminating the splitter and the
long mic level cable runs. And because the microphones are now
driving a short cable and only one preamp, all the sonic degradations
caused by the traditional system are eliminated.
Pearl Jam as a band and as an organization is fanatical about audio
quality. For example, they do not use any wireless microphones.
They are equally fanatic about capturing the energy of their live
performances. When the opportunity arose to experiment with a
method that fulfilled both goals, they jumped on it.
Brett Eliason is the band's Front-of-House Mix engineer. He already
had some experience with the 1788 so he specified them with
confidence. But after using them for several concerts he is thrilled
with the quality increase of both the recording and PA systems.
Compared to the recordings made in Europe using the traditional
system, Brett says that the tracks are "fuller, punchier and warmer.
The differences are not subtle and everyone who has listened to
the new tracks has been very impressed."
There have been dramatic differences in the PA as well. Brett reports
"there is more real low end and smoother high end. It has eliminated
the mid-range 'honk' of the house PA."
A feature of the 1788 that has proven useful is MicLim - a limiter on
the output of the microphone before the preamplifier. Eddie Vedder
plays an acoustic guitar that is miked with a Fishman acoustic pickup.
He usually plays very softly and the preamp is set up with lots of gain.
One concert he decided to strum hard and if it were not for the
MicLim the guitar would have been totally distorted.
"Once the mic pre's were set up they have worked flawlessly. They wake
up exactly how they were left at the last concert and I can easily load
a preset if needed. There are no clocking problems on the digital
outputs. The analog outputs to the house and monitor positions are
much cleaner than what we had before. We are very happy
with the change."
