Audio
Delay for professional and Broadcast use
On this
page, we outline some of the key features of the MDOUK Broadcast
delay, whilst on the operation
page, there's a step-by-step guide to working with this professional
audio delay.
The
user interface
The
user interface is simple, clean and clear. The PC screen allows you to
see the current system status at all times,
with audio meters, delay status and other operational detail laid out
in large clear areas. And
as you would expect from a broadcast tool like this - it does not require
any further attention after it has started doing it's work!
Despite
the advanced functionality of the broadcast delay during a show, the operator
only ever needs to use two buttons. This makes the system incredibly
easy to use - for both DJ/Self-op setups and control room use.
Large
meters with peak indicators and dB scale show the input and output
(delayed) signal level. |
|
|
Three
easy to use up/down buttons to preset the
delay. During the manual start these displays will
show the current delay. |
Big,clearly
labeled buttons make it easy to operate the Broadcast delay.

The
computer hardware
The
Broadcast delay runs on any standard PC. It simply requires a standard
sound card - from cheap on-board devices up to high quality professional
audio cards. We recommend a good quality sound card as
your entire programme output passes through the card whilst the delay
is in circuit.
The
delayed audio is stored on the computer's harddrive. The table
below shows how much free space is required a couple of delay times depending
on the samplerate.

Required
free hard drive space depending on the samplerate |
To
get the space needed for a 6 minute delay at 32000 Hz
just take the 1 minute figure from the table above
and multiply this by 6. The figures in the table
are calculated for stereo operation - for mono
operation only half the space is required.
Your
audio is only stored on the harddrive until it is played out.
This means that you can leave the Broadcast delay running 24/7 without
requiring more free space. The system cleans up after itself
- there is no need to manually remove old audio from the system.
