About Encore Welcome to the Encore family! Encore is a modern, high-quality range of products designed around a common hardware and software platform. The Encore family includes: Audio processors § RDS coders § Stereo generators § Rebroadcast receivers § Audio backup devices §...
Page 4 All product-specific settings are contained within the ‘Presets’ menu – providing an automobile radio -like interface which works just as well for profiles in an RDS encoder as it does for settings in an audio processor, a modulation monitor or rebroadcast receiver. The web remote control interface is common across all products, as is the API and the internal language, so it’s simple to interface the whole Encore range of products with your common monitoring and telemetry system.

Page 11: User Interface
User Interface NAVIGATING Encore products have an intuitive interface based around a pushable scroll knob, surrounded by a ring of LEDs, with a series of buttons. Some products have three buttons, some five and some six. The buttons can be ‘soft keys’, and perform various functions denoted by icons shown adjacent to them in the displays, or may be function-specific - in which case the buttons are illuminated with the following symbols: ONLINE...
Page 12 The icons that can be shown against the softkeys are as follows: If the ‘scroll screen left’ or ‘right’ icons are displayed, this indicates that there are additional screens available. Pressing these buttons slides the displays to and from these other screens. ‘Back’...

7.1.1 AUDIO CONNECTIONS The analog audio outputs are balanced XLR connectors (pin 2 +ve) and can range from peak levels of -10dBu to +24dBu. The menus in the ModMon Encore are used to calibrate the audio levels to suit your facility.
Page 15 7.1.3 ANTENNA CONNECTIONS The two antenna connectors, labelled ‘FM 1’ and ‘FM 2’ on the ModMon Encore’s rear panel connect internally to the two separate tuner modules. Depending on your application, you may wish to use two separate antennas, or one antenna with a good quality splitter or distribution amplifier.

Page 18 Otherwise that output will continue to carry the audio from one of the tuners irrespective of the actions of the A/B buttons. The reason for this option is that you may be using the ModMon Encore to feed off-air audio from your station via its audio outputs to your facility for confidence monitoring;...
Page 19 THE SYSTEM MENU This menu contains all the fundamental unit configuration settings, and should be the first place you go after taking the Encore out of its box! These settings are peculiar to the installation, perhaps the transmitter site itself, as opposed to the following ‘Presets’...
Page 20 8.1 AUDIO I/O (Certain menu items are omitted in some products in the Encore range). Within this there are two submenus – ‘inputs’ and ‘outputs’. ‘Inputs’ allows you to set the operating level of the unit when referenced to the rest of your installation.

Page 23 The other option available in this menu is ‘polarity’ – where you can set each pin to output either active Hi-Z (high impedance) or active low (i.e. connected to 0v). The Events and Triggers port pinouts are: Next is the list of the 8 available events, each of which can perform a variety of actions when triggered.

Page 27: Presets Configuration
If this block shows the letter A, this indicates that the preset has been selected by an ‘action’ from the ‘events’ section of the ModMon Encore (see section 8 in this manual). If the block shows the letter S, the preset has been selected by a ‘schedule’ event.
Page 28 If you have a user preset loaded, and you then load one of the factory presets, the receive frequency and deemphasis settings are not altered. The ModMon Encore will in this case apply the rest of the processing and refinements contained within that factory preset.
Page 29 If you’re using the ModMon Encore to monitor the audio of your or any other off-air transmission, it’s probably worthwhile starting off by loading the F1 Monitor preset, then setting your frequencies before saving to a user preset.
Page 30 In this case, please use the F2 Measure preset as the basis for your user presets. Be aware though that in this case, due to the effects of ultrasonic noise and multipath interference, the ModMon Encore’s modulation readings will be affected by these factors, and will not be a true representation of your transmitter’s performance.
