The Audio Interface |
|
The BlueBox
includes one mic/line switchable input,
one headphone output and one line level output |
| |
on XLR, providing direct
connection to mics and headphones or a mixer. |
| |
An additional -10 dbu tape
input allows connection to a minidisc or DAT player. |
| |
The BlueBox contains an internal
peak limiter. |
|
Phone Line Features |
|
The BlueBox
(like the Matrix) adds several utilities which aid in ease of
use and reliability on difficult |
| |
phone lines. |
| |
The unit automatically detects
the optimal data rate and delivers the best audio possible.
|
| |
A Max Rate (Maximum Data
Rate) can be set prior to connection, giving further assurance
of stability. |
| |
A quick rate drop feature
sets a new Max Rate for reliability with only a 2 second loss
of audio. |
| |
Renegotiation can be disabled,
preventing drop outs at inconvenient times. |
| |
A quick rate drop or a full
renegotiation can be performed at any time by pressing a single
button at |
| either end of the call. |
| |
Error correction is available.
|
| |
And even at 14.4 kb/s, the
BlueBox will deliver 7 kHz audio (see frequency response chart).
|
| |
Comrex has implemented every
tool possible to aid you in delivering a seamless and uninterrupted
|
| broadcast. |
|
Cellphone Operation |
|
The BlueBox
provides a jack for connection to the 2.5 mm hands-free port
on mobile phones. |
| |
(Adapters are available
for most phones from www.cellularaccessory.com/audioadapter.html.) |
| |
This utility
does not add any audio enhancement to the wireless call, but
it makes a useful back-up tool. |
| |
Adding professional microphones
will often improve audio quality. |
| |
Calls can be placed to regular
telephone hybrids |
| |
(no BlueBox or other codec
is required on the receiving end of the call). |
|
Other Noteworthy Features |
|
Two contact closures are
available at each end of the BlueBox. One is automatically enabled
upon |
|
connection. |
|
The second is a momentary
contact closure that can be initiated by pushing a button on
the keypad. |
|
The BlueBox
gives the option of automatically answering a call or letting
you answer manually. |
|
The BlueBox
may be dialed from an external telephone. |
|
The BlueBox
may be programmed for any of 20 different international dialing
protocols. |
|
It will also work on virtually
any A/C power in the world. |
|
Up to 44 digits (including
pauses) can be entered into the BlueBox's dialer - useful for
credit card or |
|
international calls. |
