INTRODUCTION ORBAN MODEL 5700i
•
The 5700i is designed and certified to meet all applicable international safe-
ty and emissions standards .
Adaptability through Multiple Audio Processing Struc-
tures
•
A processing structure is a program that operates as a complete audio proc-
essing system. The 5700i realizes its processing structures as a series of high-
speed mathematical computations made by Digital Signal Processing (DSP) chips.
•
The 5700i features four processing structures: Five-Band (or “Multiband”) for a
consistent, “processed” sound with 17 ms delay (typical), free from undesirable
side effects,
Low-Latency Five-Band (12 ms delay), Ultra-Low-Latency Five-
Band (3.7 ms delay), and Two-Band (17 or 22 ms delay) for a transparent sound
that preserves the frequency balance of the original program material. A special
Two-Band preset creates a no-compromise “Protect” function that is functionally
similar to the “Protect” structures in earlier Orban digital processors.
•
The 5700i can increase the density and loudness of the program material by
multiband compression, limiting, and clipping—improving the consistency of the
station’s sound and increasing loudness and definition remarkably, without pro-
ducing unpleasant side effects.
•
The 5700i rides gain over an adjustable range of up to 25 dB, compressing dy-
namic range and compensating for both operator gain-riding errors and gain in-
consistencies in automated systems.
•
The 5700i’s Two-Band processing structures can be made phase-linear to maxi-
mize audible transparency.
Controllable
•
The 5700i can be remote-controlled by 5-12V pulses applied to eight pro-
grammable, optically-isolated “general-purpose interface” (GPI) ports available
at the REMOTE INTERFACE connector on the rear panel.
•
5700i PC Remote software is a graphical application that runs under Windows
2000/XP/Vista/7. It communicates with a given 5700i via TCP/IP over modem,
direct serial, and Ethernet connections. You can configure PC Remote to
switch between many 5700is via a convenient organizer that supports giving any
5700i an alias and grouping multiple 5700is into folders. Clicking a 5700i’s icon
causes PC Remote to connect to that 5700i through an Ethernet network, or ini-
tiates a Windows Dial-Up or Direct Cable Connection if appropriate. The PC Re-
mote software allows the user to access all 5700i features (including advanced
controls not available from the 5700i’s front panel), and allows the user to ar-
