INTRODUCTION 1 1 CM-CU1 Commentator Unit Introduction INTRODUC TION Fig 1-1: CM-CU1 Commentator Unit The CM-CU1 Commentator Unit is a high quality, portable broadcast mixer and 4-wire talkback unit. Its sturdy construction and flexibility of features make it suitable for use in a wide variety of environments. It provides a fully featured commentator position with both limited, transformer balanced, and non-limited, electronically balanced outputs.
1 INTRODUCTION A GPIO port gives an open-collector driven output indication of any active on air or talkback channels, and four remote inputs provide an external call/alert to each of the talkback controls. INTRODUC TION The Commentator Unit has a built in line-up tone generator for easy channel identification and cabling checks, and a flexible range of options allow the unit to be customised to better suit the operational and users’ personal requirements.
MAIN CONTROLS & INDICATORS 2 2 Main Panel Controls & Indicators The main panel of the Commentator Unit is split into two areas. At the top are the mix output PPM meter display, mix output limiter active indicator and the power indicator LED. Below this are the main commentator position controls, with the TALKBACK and ON AIR buttons located towards the bottom.
2 MAIN CONTROLS & INDICATORS MAIN CONTROLS & INDIC ATORS Prog, A, B, C and D function normally when a Talkback channel is active, allowing fullduplex communication between the commentator and a third party. These buttons have a momentary action by default; press to activate, release to deactivate. See Page 9 ‘Config Page 1 - ON AIR Button Enable/Disable & TALKBACK Button Latching Modes’ for details of how to change the button action.
FRONT PANEL CONTROLS & CONNECTIONS 3 3 Front Panel Controls & Connections The front panel of the Commentator Unit has the commentator input and headphone output as well as the microphone power and gain controls. Phantom Power Select Switch The commentator input supports phantom powered microphones. The commentator position has a dedicated phantom power switch that enables the 48V supply. Microphone Input Gain Controls The commentator microphone input has an adjustable gain setting.
4 REAR PANEL CONTROLS & CONNECTIONS REAR PANEL CONTROLS & CONNEC TIONS 4 Rear Panel Controls & Connections Fig 3-2: Rear Panel View Of CM-CU1 The rear panel of the Commentator Unit carries the five return audio inputs and commentator, talkback and mix output connectors. Four additional controls are located on the rear panel; On Air Lock, Talkback Gang, Limiter and Test Tone. On Air Lock Controls The On Air Lock prevents the commentator’s ON AIR button from being deactivated accidentally.
REAR PANEL CONTROLS & CONNECTIONS 4 Test Tone Manual Mode With the test tone in manual mode, the ON AIR and TALKBACK buttons flash amber. The test tone can be routed to the Comm and Talkback Outputs by pressing the ON AIR or corresponding TALKBACK buttons. The ON AIR button illuminates red when pressed and the TALKBACK buttons illuminate green. When the button is released, the tone on that output is muted.
4 REAR PANEL CONTROLS & CONNECTIONS Pin 1: 0V Pin 2: No connection Pin 3: No connection Pin 4: +VE (12-24 Volt DC) REAR PANEL CONTROLS & CONNEC TIONS When powering the CM-CU1 via the DC supply input, it is important to ensure that the unit is suitably earthed. An earth connection point is provided on the rear panel in the form of a M4 stud and screw and this should be connected directly to a technical earth. 8 GPIO Port The CM-CU1’s GPIO port has 5 open-collector driven outputs and 4 active low inputs.
CONFIGURATION OPTIONS 5 5 Configuration Options The CM-CU1 has several user configurable options that can be changed to suit specific operational or personal requirements.
