1. Status indicator (green)
Lights when the speaker is placed in fault state*
This indicator may light arbitrarily during PC
communication using the SR-D8 PC Software.
*
The state in which audio signal can be directly
1
input from the Analog 1 input terminal (4) to
a digital amplifier without passing through the
speaker's internal CPU by shorting the fault
contact input terminals (5).
2. rUN indicator [rUN] (green)
Flashing:
Correct operation of the unit.
Lit or Unlit: Abnormal operation of the unit.
3. power indicator [pOWer] (blue)
Lights when the power is switched ON.
4. Analog input terminals [FAULT SIgNAL/
ANALOg 1, ANALOg 2]
Removable terminal block (3P) with electronically-
balanced inputs.
(H: Hot, C: Cold, E: Ground.)
The ANALOG 1 input terminal can be used to
directly input audio signal to the digital power
amplifier, bypassing the unit's built-in CPU, when
the Fault contact input terminal (5) is shorted.
Note
Up to 4 units' terminals can be connected in
parallel.
5. Fault contact input terminal [FAULT cONTrOL]
Used when audio output is interrupted due to
failures in the built-in digital signal processor
(DSP) or other circuit.
Shorting between the terminals of removable
terminal blocks (2P) allows audio signals to be
directly input to the built-in digital power amplifier
from the ANALOG 1 input terminal (4), bypassing
the unit's built-in DSP.
Therefore, the directivity control (variable beam
function) cannot be performed through the DSP.
Notes
• As this terminal is a no-voltage contact input,
never apply any voltage to it.
• Up to 4 units' terminals can be connected in
parallel.
6. MAc address (cobraNet)
MAC address for CobraNet.
7. MAc address (cONTrOL)
MAC address for the LAN.
8. Local link output terminal [LOcAL LINk OUT]
Outputs signals from SR-D8-M to SR-D8-S's
Local link input terminal (14) when interconnecting
SR-D8-M and SR-D8-S units in multi-unit
configuration.
Use RJ45 connector.

equipment to these terminals via a switching
hub. Connect the PRIMARY and SECONDARY
terminals to a single switching hub or 2 cascade-
connected hubs. Use RJ45 connector.
