Manual Logos 1.2 Fader section Microphone channel The left fader is always the main microphone channel. If configured as a Controlroom microphone (factory default setting), the monitor loudspeakers are muted and the red-light indicator is switched on upon opening the microphone fader. If the microphone is configured as Studio microphone this indicator will stay dark and the monitor loudspeakers are not muted.
PAGE 4
Manual Logos Holding the button down longer (long-press function) activates the source dependent set-up menu. In this menu you can set both gain and balance level for that source. Pushing the button shortly (short-press function) activates the prefade listening (PFL). The speakers, headphone and program level meter reproduce the signal of the selected source. The last two buttons are used for monitoring the Main output and the Talkback function.
PAGE 5
Manual Logos 1.6 Transport control section The Transport control section consists of ten pushbuttons to control audio editors. The Logos offers support for the following audio editors: • Dalet • Digigram X-track • Netia The actual function of these buttons depends on the audio editor used and on the settings made within this program. In most cases, the user will be able to configure the function of these buttons. These keys are active only for the selected device and will be disabled with open fader. 1.

Manual Logos 2 The rack-unit (D902) 2.1 Front side connectors D 902 POWER DIGITAL I/P L INPUT 1 R HPH 1 Digital input The most left input of the rack-unit is the AES/EBU and SPDIF tolerant digital input. The audio modes of this input can be configured in the LogosTool. Setting the gain level for this input can be done by long-pressing the key in the Monitor section, which opens the set-up menu for this input.
PAGE 7
Manual Logos 2.2 Rear side connectors Mains supply The mains inlet connector is a Neutrik PowerCon connector (NAC 3FCA, blue). This connector provides a safe and reliable mains connection without the risk of accidentally disconnection, as with standard IEC types. Mains inputs ranging from 90 VAC to 264 VAC are accepted. Inside the build in power supply there is a F2,5A/250V fuse. If this fuse needs to be replaced, replace it only with Shurter SP0001.1008 or Littelfuse 21602.
PAGE 8
Manual Logos On all modules, inputs are always combined with outputs on the one sub-D25 female multipin connector on the board. Also signalling, fader start/stop (GPIO) is present on this connector. In general: GPI are inputs low active and GPO are isolated optocoupler outputs for collector and emitter (with If max= 30 mA, max. 70 Volts). External meter output This ¼ inch jack connector provides an output to connect an external modulation meter (e.g. RTW).
PAGE 9
Manual Logos 3 LogosTool software LogosTool is a Windows computer program for Windows 95/98 and NT clients. To use the software, connect a computer with the Logos (rackunit). The computer should be connected with the ‘RS232’ port of the Logos. The characteristics of the communication between PC and the Logos are: 9600 baud, 8 databits, no parity, no handshake. Described is version 1.0.0 (build 18) to be used with Logos firmware version 1.43. Configurations made with versions of the LogosTool older then 1.
PAGE 10
Manual Logos 3.2 Toolbar New configuration With this button you can make an entirely new configuration. You can also make a new configuration by altering an existing configuration and saving it with a different name. Load configuration from disk Loading a previously made configuration to alter it or to download it to the Logos. Save configuration to disk Save the active configuration to a disk for later use. Update firmware to Logos Upload a new firmware version to the Logos.
PAGE 11
Manual Logos 3.3 Tabs Depending on the number of input / output modules used, the LogosTool will display a number of tabs, in which all kinds of parameters can be changed. Hardware tab This tab shows the configuration of the modules. The Logos does not automatically detect which kind of input module is present. Selecting or de-selecting an input module will make the corresponding tab appear or disappear.
PAGE 12
Manual Logos Possible functions for GPO-A and GPO-B (outputs) are: • None • Timer start, impulse contact closure • Timer start microphone, impulse contact closure • Timer start line channel 1, impulse contact closure • Timer start line channel 2, impulse contact closure • Timer start line channel 1 & 2, impulse contact closure • Call detect, contact closure on detecting an incoming telephone call • Controlroom microphone On • Studio microphone On • Split/rec Off / On Set name The name that will be displayed
PAGE 13
Manual Logos By default the monitor will switch to main output upon opening the main microphone. Monitor select by open microphone allows you to select a different monitor source the unit will switch to upon opening this fader. (Only available from Logos firmware version 1.40 onwards). This selection can also be done through the microphone menu of the desktop unit, see Chapter 6). Front inputs Tab For both Analogue and Digital Front Inputs a name can be entered (8 characters) and the mode can be selected.

Manual Logos 4 Start-up of the Logos After turning on the power of the Logos, the initialising process will start and after a few seconds the Logos will be ready for operation. Upon start-up the version number of the embedded software and the text "initialise" will be displayed in the LCD screen. Upon start-up the left fader will have default the Digital Front input selected while the right fader will have the Analogue Front input selected.
PAGE 17
Manual Logos 5 Source configuration A short-press selects one of 8 sources on the PFL / Monitor selector. Now you can listen to that source (pre-fader). Pressing the selector button a longer time (long-press) selects the set-up menu for that source. You can scroll through the menu with the function keys, (up), (down), by turning the JOG-wheel or entering the appropriate number on the numeric keypad. Pressing the key will display the selected menu.

Manual Logos 6 Microphone adjustments TALK 6.1 Accessing the menu MAIN O/P On the PFL / monitor selector press and
both for a longer time to change the microphone settings. You can scroll through the following options: • Gain • Pan • Phantom • HighPass • Insert • Compressor/Limiter • Ducker • MonitorSel. Use the function keys (down) and (up), or the Jog/Shuttle-wheel or the appropriate number on the numeric keypad for selecting a parameter.
PAGE 19
Manual Logos 6.4 Insert bypass The function key F1 will switch the bypass of the insert point and therefore disables the Insert. The LED will indicate the ON- status. (The insertion is disabled). For more information about the Insertion point, see Chapter 2 (Rearside connectors). Bypass 6.5 Compressor / Limiter toggles the Compressor / Limiter active or not. The LED in the key indicates the active On status. Turning the JOG-wheel will adjust the Threshold (max. microphone output level).
PAGE 20
Manual Logos 6.7 MonitorSel The Monitor Select function is used for selecting the input whereto the monitor will switch upon opening the microphone channel. The possible options are (where xxxxxxxx is the name of the input): • DigitalFront • Analog Front MonitorSelection • IO3-xxxxxxxx DigitalFront • IO4-xxxxxxxx Analog Front • IO5-xxxxxxxx • IO6-xxxxxxxx • IO7-xxxxxxxx • IO8-xxxxxxxx • Main Note: this function is also available in the LogosTool software. See Chapter 3.
