Parallel Connection
Contacts for each of the SRA-200E's three types of
input connectors (XLR-3-31, TRS standard phone, and
screw type) are wired in parallel internally, so signals
can be output unchanged and then input again at a
separate device's connector, allowing connection of a
multiple number of power amps.
*With parallel connections, the total impedance is
reduced. Check the output impedance of each device
to be connected (mixer, preamps, and so on) to make
sure that the outputs of the mixer and other devices
do not overload the system.
●
The input impedance of a single SRA-200E itself is 10
kiloohms (with balanced or unbalanced input).
●
The total input impedance of "n" number of SRA-
200Es connected in parallel is "10/n" kiloohms (with
balanced or unbalanced input).
