Page: 9 / 25

There are also TRS jacks for linking etc. They are wired as follows:
TIP - HOT (+)
RING - COLD (-)
SLEEVE - SHIELD/SIG. GROUND

The input impedance is sufficiently high (20k ohms balanced) to allow
"daisy-chaining", or multiple parallel input connections. To daisy-chain, use
the TRS jacks provided on each channel. The input circuits also have high
enough headroom to accept the maximum output level from virtually any
low-level signal source.
