Dynacord CPA 2000 User Manual

4. Inputs
4.1 Input 1
INPUT 1 ([40] or [41]) lets you connect sound sources with output levels, reaching from 0.5 mV to 1.3 V.
The connector (INPUT 1, [40]) is specially meant for the connection of microphones with PTT button (e.
g. the DYNACORD MT 101), providing you with the advantage of a single connection for the signal and
the switching of the priority function. The pin-assignment of the XLR-socket (INPUT 1, [41]) is: 1=ground,
2=pos. input (+), 3=neg. input (–).
Using the sensitivity selector switch (MIC / LINE, [42]), you can determine if the input’s sensitivity is high
(for the connection of microphones, the button is not engaged) or low (for line-level equipment, the button
is engaged). The GAIN [43] control has to be adjusted, so that the optimum internal operation level is
achieved (the Clip-LED of the meter instrument [15] lights only frequently) when the input control (MIC 1,
[1]) as well as the MASTER [6] control are both set at their 2 o’clock position (“7" marking of the printed
scale). The MIC 1 [1] control lets you adjust the input level of input 1. The corresponding TREBLE [7] and
BASS [8] controls can be used to match the channel’s sound according to acoustical conditions of the
installation site. The connection of unbalanced line-level sources makes internal bridging necessary, using
the jumper J 101.
Important Note: In case the priority function is activated, the MASTER [6] control is bypassed. No gong,
alert signal, or voice message should be activated. The speaker zone has to be assigned before activating
the priority function!
When using the priority function, a priority has to be set which is controlled via the INPUT 1 [40] connector
or the REMOTE CONTROL [58] connector. See also paragraph 7 (Priority function).
4.2 Input 2
INPUT 2 [44] lets you connect sound sources with output levels, reaching from 0.5 mV to 1.3 V.
The pin-assignment of the XLR-socket (INPUT 2, [44]) is: 1=ground, 2=pos. input (+), 3=neg. input (–).
Using the MIC / LINE [45] selector, you can determine if the input’s sensitivity is high (for the connection
of microphones, the button is not engaged) or low (for line-level equipment, the button is engaged). The
GAIN [46] control has to be adjusted, so that the optimum internal operation level is achieved (the Clip-LED
of the meter instrument [15] lights only frequently) when the input control (MIC 2, [2]) as well as the
MASTER [6] control are both set at their 2 o’clock position (“7" marking of the printed scale). The MIC 2
[2] control lets you adjust the input level of input 2. The corresponding TREBLE [9] and BASS [10] controls
can be used to match the channel’s sound according to acoustical conditions of the installation site. The
connection of unbalanced line-level sources makes internal bridging necessary, using the jumper J 105.
Important Note: In case the priority function is activated, the MASTER [6] control is bypassed. No gong,
alert signal, or voice message should be activated. The speaker zone has to be assigned before the
priority function is activated!
When using the priority function, a priority has to be set which is controlled via the INPUT 1 [40] connector
or the REMOTE CONTROL [58] connector. See also paragraph 7 (Priority function).
If microphone terminals MT 2005 are connected to the RJ 45 socket, the MT 2005 are using this LF-input
and no other sound sources can be connected. The MIC / LINE [45] selector has to be set for low sensitivity
(button is engaged) and the corresponding GAIN [46] control should be adjusted at its approximate center
position.
4.3 Input 3
INPUT 3 [47] lets you connect sound sources with output levels, reaching from 0.5 mV to 1.3 V.
The pin-assignment of the XLR-socket (INPUT 3, [47]) is: 1=ground, 2=pos. input (+), 3=neg. input (–).
Using the MIC / LINE [48] selector, you can determine if the input’s sensitivity is high (for the connection
of microphones, the button is not engaged) or low (for line-level equipment, the button is engaged). The
GAIN [49] control has to be adjusted, so that the optimum internal operation level is achieved (the Clip-LED
of the meter instrument [15] lights only frequently) when the input control (MIC 3, [3]) as well as the
MASTER [6] control are both set at their 2 o’clock position (“7" marking of the printed scale). The MIC 3
[3] control lets you adjust the input level of input 3. The corresponding TREBLE [11] and BASS [12] controls
can be used to match the channel’s sound according to acoustical conditions of the installation site. The
connection of unbalanced line-level sources makes internal bridging necessary, using the jumper J 109.
