Available in 120, 240 and 600-watt models, the audio power amplifi- ers provide flexibility and versatility without the need for add-on modules. Each model offers state-of-the-art, built in Digital Signal Processing (DSP) software that includes factory loudspeaker presets and that turns the amplifier into a complete audio solution. A short press of the appliance’s Reset button reboots the device. If you press the Reset button for 10 seconds, the appliance returns to the factory default configuration settings. Returning to the default configuration settings does not change the appliance’s firmware. The following sections describe the process for manual configuration. For information about using Nyquist’s automatic configuration pro- cess, refer to the Nyquist System Administrator Manual. Note: Do not use third-party Chrome browser extensions with the Nyquist user interface. To access the appliance’s UI: Step 1 Access the appliance’s web UI by doing one of the fol- lowing: a On your web browser, enter the IP address for the appliance as the URL. b From the Nyquist web UI navigation bar, select Sta- tions, select Stations Status, navigate to the device 1 that you want to configure, and then select the Link icon. Figure 1, Nyquist Appliance Login Step 2 At the Nyquist Appliance - Login page, enter username and password, and then select Login. The default username is admin; the default password is bogen. The dashboard for the selected appliance appears. Figure 2, Matrix Mixer Pre-Amp Dashboard 2 1 Using the Dashboard The dashboard displays the following read-only fields: Table 1, Appliance Dashboard Read-Only Fields Device Type Identifies the physical device used by the station. Serial Number Identifies the serial number for the device. MAC Address Specifies the Media Access Control (MAC) address, which is a unique identifier assigned to network interfaces for commu- nications on the physical network segment. Firmware Version Provides the firmware version installed on the station. The dashboard also contains the following buttons: Table 2, Appliance Dashboard Buttons Dashboard Refreshes the dashboard. Configuration Set- Accesses the Configuration Settings page tings where you can either manually set various options, such as the SIP Username, or select to receive configuration settings from the server. Network Settings Accesses the Network Settings page where you can view and set network settings, such as the static IP address. Firmware Update Accesses the Firmware Update page where you can view the current Nyquist version, check for updates, restore factory settings, and reboot the appliance. Logs Accesses log files, which record either events or messages that occur when soft- ware runs and are used when trouble- shooting the appliance. DSP Accesses the DSP page where you can view and set parameters for Digital Signal Pro- cessing (DSP). 3 Table 2, Appliance Dashboard Buttons Help Accesses the appliance’s online help. Manual Displays the Nyquist Matrix Mixer Pre-Amp Configuration Manual. Logout Logs out of the appliance’s dashboard. 2Updating Firmware When you select Firmware Update from the appliance’s web UI, the Firmware Update page appears. From this page you can determine which Nyquist version the appliance is using and if an update is required. You can also use this page to restore factory settings and to reboot the appliance. Note: A Nyquist appliance connected to the Nyquist network receives a config- uration file from the Nyquist server that includes the latest firmware available from the server. If the firmware is later than the one installed on the appliance, an automatic firmware update occurs unless the Firmware parameter for the sta- tion is left blank. Refer to the Nyquist System Administrator Manual for more information. Figure 3, Firmware Update Page 4 To use the Firmware Update page: Step 1 On the appliance web UI’s main page, select Firmware Update to ensure you have the latest firmware version. Step 2 Select Upload Firmware to upload firmware from the server to the appliance. If you select this option, a popup screen appears that allows you to select the file that you want to upload. You can navigate to the file’s location. After you select the file, select Upload. If Nyquist discovers a new firm- ware version, the Firmware Update page displays an Update Firmware button. Select this button if you want to update the appliance’s firmware to the new version. Step 3 If you want to return your appliance to its original state (undoing firmware updates), select Restore Factory Settings. Step 4 Select Reboot Appliance to restart your appliance. 3 Setting Network Tab Parameters Network settings can be configured dynamically by the Nyquist server or manually by using the appliance’s web UI. To manually configure network settings: Step 1 On the appliance web UI’s main page, select Network Settings. Step 2 Select your desired network settings. Step 3 Select Save. 5 Figure 4, Network Settings Network settings are described in the following table: Table 3, Network Settings Static IP Identifies the fixed IP address assigned to the appliance by a system administra- tor. Netmask Identifies the subnetwork subdivision of an IP network. Gateway Identifies the address, or route, for the default gateway. VLAN ID Identifies the Virtual Local Area Network (VLAN) for this appliance. Values range from 0 to 4094. 6 Table 3, Network Settings (Continued) VLAN Priority Identifies the priority of the network traf- fic on the VLAN. Priority can range from 0 through 7. NTP Server Identifies the IP address or the domain name of the Network Time Protocol (NTP) Server. This field is read only. TFTP Server Identifies the IP address

    build a Ital transposer TIGER .01 Introduced three years ago, our "Tiger .01" is still one of the finest amplifiers available in its power class. This amplifier introduced our 100% complementary circuit which has become a standard feature in many of the better amplifiers. This combined with an output triple produces a circuit that can honestly be rated as having less than .01% IM distortion at any level up to 60 Watts. Relatively low open loop gain and a conservative amount of negative feedback results in clean overload charac­ teristics and good TIM characteristics. Other features are volt-amp output limiting, plus three fuses and an overheat thermostat. Despite the "budget” price an output meter is standard equipment. Each channel measures 4% x 5 x 14. Four will mount in a stan­ dard width relay rack for four channel systems. SPECIFICATIONS 60 Watts—4.0 or 8.0 Ohm load Minimum RMS from 20 Hz to 20 KHz with less than .05% Total Harmonic Distortion.
