2.On the SSA-424A front panel, set the 4W LEVEL REF SEL switches to the position which most closely matches
the audio input and output levels of your 4-wire system. If you don’t know the levels, select the +8 dB position for now.

1.Use standard TW intercom cables. Standard TW system cables can carry either one or two channels, while each hybrid in the SSA-424A can only interface one TW
channel to one 4-wire channel, which channel is determined by the front panel 2W CHAN SEL switch. If your TW system cable is only carrying one channel, or if you only need to connect one of two channels, connect directly to J1A (System A) or J1B (System B). If your TW system cable is carrying two channels, and you want to connect to both, use a TW-5W or similar device as shown in Figure 3 on page 7.
