Page 12: Section Ii - Installation
Section II INSTALLATION GENERAL This section of the manual addresses the physical installation of the 541 at its operating location, the ‘nuts and bolts’ of connect- ing the unit. This section also references pages where pertinent setup options and adjustments are discussed. As soon as the equipment is received, inspect carefully for any Unpacking and shipping damage. -

If you need to replace the North-American mains plug with an- other, you will find that the individual cord conductors are color- coded in one of two ways. -

Dante/AoIP streaming first requires basic Dante setup under the Webpage or LCD Dante menus as detailed on Pages 43-44. Output levels are adjusted on the Setup / MPX and Audio Outputs / Dante Output Webpage, or under the LCD Setup / Dante Outputs menu. -

Up to 10 listeners can access this audio stream simultaneously, but listeners may also be restricted.

pass function following the SCA demodulator. Use these con- trols to clean up the audio as best you can. Deviation (kHz): defines the 100%-modulation point of the SCA subcarrier. The default value of ±5kHz is the de-facto specifica- tion, although FM subcarrier parameters are no longer subject to government regulation in the US. -

Finally, you must program the Rotation Time (Sec):, and this may take some planning. Many of the 541 alarms have Time On (Sec): and Time Off (Sec): settings that will impact your Rotation Time (Sec): choice. See the Alarms discussion beginning on Page 34. The Status: display gives a second-by-second countdown of rota- tion time or shows that the feature is Off. -
Page 26: Pilot, 38Khz And Rds Levels
With an appropriate filter selected (Page 19), these modulation readings should not be affected by accompanying HD Radio pro- grams. Precise IF filtering eliminates false indications of FM- overmod at any HD carrier-pair injection ratio. Any observed in- teraction between analog and digital program channels should certainly prompt further investigation. -

calculated and integrated within a floating 1-minute measure- ment window. As a point of reference, 0dBr equates to the r.m.s. power of a single-tone sinewave modulated with a peak deviation of ±19kHz, which is some 12dB below the ±75kHz FM peak devia- tion limit. -
Page 28: Fm Program Loudness
XTalk (stereo crosstalk) is similar to the Sep (stereo separation) measurement, but in this case it indicates the level difference between the L+R and L-R program audio components. Like the Sep readout, it is useful only with tone tests and is not an indi- cation of crosstalk issues in the program audio. -
Page 29: Sca Subcarrier Measurements
Loudness Window: down to 30 seconds, as may be dictated by the station’s programming format. This metering method reflects the broadcast implementation of the BS.1770 Standard, and is explained in further detail in EBU Loudness Standard R-128. SCA Subcarrier Measurements The % scale shows the injection level of the SCA subcarrier in percent of total FM carrier modulation. -
Page 30: Spectrum Plots
SPECTRUM PLOTS The 541 monitor includes an advanced, high-resolution FFT- based spectrum analyzer that delivers detailed and annotated graphic displays of selected signals. Images may be viewed ei- ther through the Webpages utility or from the front-panel LCD- touchscreen. Each signal selected for viewing carries its own family of graph setup options below the display. -

Peak will show the peak value of the sig- nal, and Hold accumulates the highest peak value until the func- tion is deselected. At the bottom, the display Averages: the number of FFT compu- tations selected in the drop-down box. -
Page 32: History Plots
HISTORY PLOTS The 541 offers plots of reception and audio parameters viewable over a specified time period, from the past minute to a full, 24- hour time study. Although these data are available through both the Webpages and front-panel LCD-touchscreen displays, Webpage presenta- tion provides some extended options covered in this discussion that will be found missing with front-panel operation. -

Page 35: Oscilloscope
OSCILLOSCOPE A built-in oscilloscope utility has been included for viewing au- dio and other waveforms through either the Webpages or the LCD-touchscreen displays. Vertical sensitivity is scaled and an- notated with respect to the 100%-modulation point, and the hor- izontal timebase adjusts for the most meaningful display of the selected signal. -
Page 36: The Bandscanner™ Utility
THE BANDSCANNER™ UTILITY The 541 BandScanner is an annotated RF spectrum analyzer util- ity that is able to graphically display the entire FM band. From the front panel, BandScanner is found under Graphs. 1) Band-scanning interrupts all mod-monitor functionality dur- Warnings! ing the scan cycle, as it essentially tunes across the band and collects data from each station in the market. -
Page 37: Bars And Dots
‘Hovering’ over a yellow-only bar pops up only the Freq: and Bars and Dots RSSI: in a pop-up box. At the completion of an RSSI + RDS scan, a yellow bar with a red dot indicates a station with RDS. Hover- ing over an RDS station will also present call letters and the PTY (Program TYpe) information as shown in the example. -
Page 38: Alarm Status
Clicking the Clear/Reset RDS bar at the bottom will indeed clear the registers and begin a new RDS data collection. Reset is auto- matic when the station is changed. ALARMS The 541 provides alarms for signal or program-related error con- Alarm Status ditions. -

Alarm: On ‘arms’ the Overmod function in this and all other alarms to be dis- cussed. If the alarm is turned Off, there will be no indicator on the Now Playing or Alarm Webpages, no contact closure at a rear-panel GPO terminal, nor will the 541 send SMS/text or Email alerts to station personnel or log the alarm. -
Page 40: Audio Loss
We’ll use Audio Loss as Audio Loss a typical example of a hysteresis-type alarm. Alarm: must of course be set On to arm this function. The grayed- out Level (dB): meter shows the current pro- gram level for the sta- tion being monitored. -

To enable the PI mis- match function, enter the station’s true PI code in the PI Code: box. The code being received at the moment is shown as the Current PI:. If you are confident that what you see there is indeed the PI of your station, simply enter that same hex value and click Save. -
Page 42: Sca Loss
program appropriate Threshold (%):, Time On (Sec): and Time Off (Sec): settings. Stations running an SCA subcarrier first need to set up the SCA Loss proper measurement parameters on the Tuner menu (Page 19). Only then should this alarm be used. Current SCA Injection (%): is shown so that threshold and timing sliders may be set appropriately. -

It is generally also com- patible with proprietary systems from independent manufactur- ers of AoIP-enabled products. The Dante-based AoIP utility of the 541 is quite similar to the IP Settings product’s general networking function. Like the LAN connection, the independent AoIP connection may accept IP address assign- ments in either a DHCP or Static IP assignment Mode:. -
