INTRODUCTION ORBAN
MODEL
9400
The two left and right analog output pairs are on XLR-type male connectors on the
rear panel. Output impedance is 50
; balanced and floating. The outputs can drive
600
or higher impedances, balanced or unbalanced. The peak output level is ad-
justable from –6dBu to +20dBu.
Level control of the analog inputs and outputs is accomplished via software control
through System Setup (see step 4 on page 2-24 and step 10 on page 2-30) or
through PC Remote.
Remote Control Interface
The Remote Control Interface is a set of eight optically isolated GPI inputs on a DB-
25 connector, which can be activated by 5-12V DC. They can control various func-
tions of the 9400. See page 2-46 for a list of functions and information on pro-
gramming the remote control interface.
Computer Interface
On the rear panel of the 9400 are an RS-232 serial port and an Ethernet port for in-
terfacing to IBM-compatible PCs. These computer interfaces support remote control
and metering, and allow downloading software upgrades.
Each 9400 package ships with 9400 PC Remote software, an application for any IBM-
compatible PC running Microsoft Windows 2000 (Service Pack 3) or XP. 9400 PC Re-
mote permits you to adjust any 9400 preset by remote control or to do virtually any-
thing else that you can do from the 9400’s front panel controls. The program dis-
plays all of the 9400’s LCD meters on the computer screen to aid remote adjustment.
RS-232 Serial Port
9400 PC Remote can communicate at up to 115 kbps via modem or direct connection
between the computer and the 9400 through their RS-232 serial ports.
RJ45 Ethernet Connector
The 9400 can be connected to any Ethernet network that supports the TCP/IP proto-
col.

Location of OPTIMOD-AM
Optimal Control of Peak Modulation Levels
The analog AM audio processing circuitry in OPTIMOD-AM produces a waveform
that is precisely peak-controlled to prevent overmodulation, and is lowpass filtered
to protect adjacent channels and to conform to government regulations. Severe
changes in the shape of the waveform can be caused by passing it through a circuit
