3. GENERAL DESCRIPTION
The TOA SR-D8-M and SR-D8-S are all-in-one Active Line Array Speaker Systems, each featuring a CobraNet
digitalaudioinput(SR-D8-Monly),digitalsignalprocessor,digitalpoweramplier,andspeakersconguredin
a line array. Precise control of the speaker’s vertical directivity and acoustic beamwidth makes it possible to
create fully optimized sound spaces in a wide range of locations.
All function settings can be controlled from a remote PC using the supplied SR-D8 PC Software. Equipped with
a primary audio input, the SR-D8-M transmits the audio signal to the secondary SR-D8-S via the SR-D8-M’s
dedicated local link. The local link allows up to 3 SR-D8-S speaker units to be connected in series to one SR-
D8-M, permitting a line array of up to 4 connected speakers (hereinafter, a line array speaker system consisting
ofoneormorespeakersisreferredtoas“stack”)tobecongured.Inacompletesystem,upto4stackscanbe
controlled, making it possible to build systems consisting of up to 16 speakers.

Notes
• Avoidsolderingstrandedorshieldedcable,ascontactresistancemayincreasewhenthecableistightened
and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
• Whenconnecting2cablesorashieldedcabletoasingleterminal,useaferruleterminalwithaninsulation
sleeve to crimp the cables because such cable conductors could become loose. Use the No. 4 ferrule terminal
when connecting 2 cables to a single terminal.

Step 1. Connect the wire to the supplied removable
terminal plug.
1-1. Loosen the terminal screws to insert the wire.
1-2. Tighten the terminal screws.
Ensure that the wire does not break free when
pulled. If the wire does pull free, repeat the
connection procedure from the start.
Step 2. Insert the wired terminal plug into the
corresponding terminal block in the unit’s rear
panel.
Step 3 Tightenthexingscrews.
Note
Do not reverse Steps 1 and 2 above.
Force is applied to the connected receptacle pins
while tightening the terminal screw and they may be
damaged, resulting in bad connector contact.

10.7. System Expansion Using CobraNet Connection
10.7.1. CobraNet connection outline
The system can be expanded by connecting the SR-D8-M’s CobraNet terminals to the D-2008SP with the
D-2000CB CobraNet Interface Module.
Connect the SR-D8-M to the D-2008SP via a switching hub. Connect each of CobraNet Primary and Secondary
ports of the SR-D8-M to the same switching hub or different switching hubs connected in cascade.

Notes
• MaketheCobraNetterminalscompletelyindependentfromotherLAN.
• ThedistancebetweeneachoftheSR-D8-Mandtheswitchinghubislessthan100m(110yd).
• BesuretomakeconnectionsofbothterminalsPRIMARYandSECONDARY.
• AudiosignalsmaybeinterruptedtemporarilyatthetimeofswitchingbetweenPRIMARYandSECONDARY
ports.
• When connecting CobraNet terminal PRIMARY or SECONDARY to multiple switching hubs, be sure to
connect the hubs in cascade.
• Upto7switchinghubscanbeconnectedincascade.ThenumberofswitchinghubsbetweentheSR-D8-M
and all CobraNet devices connected to the SR-D8-M should be 7 or less. (Refer to connection examples 1
and 2 on the next page.)
• Whenusingmultipleswitchinghubs,makingstarconnectionatthehubdirectlyconnectedtotheSR-D8-Mas
shown in Connection example 2 is highly recommended to reduce the number of cascade-connected hubs.
