CTP Systems DC2012, Инструкция по эксплуатации, Страница: 4 / 11

both commentators with each commentator having four individual buttons. These outputs are
electronically balanced.
Each commentator has a ‘Mic Live’ switch which can be programmed to just illuminate when the mic is
taken off air (by pressing the ‘Lazy talkback’ buttons) or as a momentary ‘Mic cut’ (or cough) switch or
as a Mic cut with toggle on and off. Setting depends on how much you trust your commentators!
48 volt phantom power is available for each microphone amplifier and selection is shown on front panel
red LEDs for each of the three inputs.
Headphone Monitoring
Each commentator has six common audio monitoring inputs with volume controls designated Talkback,
Programme, Aux 1, Aux 2, Aux 3, Aux 4. There is also an additional feed of sidetone (himself) and
another for the other commentator plus the guest microphone. Additionally there are four more
monitoring inputs, available on the multiway input, which may be selected to commentator A or
commentator B replacing the first four inputs enabling the two commentators to work to different
trucks or on different productions.
Every input may be switched via individual user adjustable mini toggle switches to left, right or both ears
of the headphones.
Headphone monitoring may be a 5 pin XLR connection with both microphone and headset connection or
3 pin XLR microphone input with TRS jack stereo headset connection. This jack socket is suitable for use
with both ¼ inch stereo and 316 (PO) jacks. The guest has his own headphone feed with a mix derived
from commentator A’s mix but with his own overall volume control. Individual commentator A feeds
may be switched away from the guest so if just, for example, a programme feed is required for the
guest.
All audio monitoring inputs are transformer isolated as standard and this is normally sufficient to
prevent any ‘Earth loop’ problems. Output transformers are available as an option.
Oh, and the headphone amplifiers go loud, capable of 500mW of audio with low distortion. Please
ensure you have audio level limited head sets if required.
Other Facilities
The rear panel MIL26 connector carries the four separate additional audio inputs or may be configured
to carry four common audio inputs to the two commentators. Two commentator outputs and a lazy
output (or two lazy outputs on 8 pair cable) are also available so, on less complicated productions, it is
possible to connect the DC2012 with just one multicore cable.
The DC2012 has a built in tone generator which can be set to identify any (or all) of the audio outputs.
Perfect for setup and identification of the audio channels with a different tone identification on each
