6.1 Setup for Multiple Inputs
With the PH-77, in addition to the use of a single cartridge/tonearm/turntable by selecting ‘Direct’ on Input switch
(R3), it is also possible to select ‘Normal’ on Input switch (R3) and connect 1, 2 or 3 different cartridge/tonearm/
turntable combinations and select them via the remote control.
For example, three different cartridge/tonearm combinations on one turntable may be connected via inputs 1, 2 and
3 for effortless switching during playback of the same vinyl record.
To setup multiple sources via the “Normal” Input option switch (R3), at the rear of the PH-77:
i. Use the ‘POWER’ rocker switch (R11) to switch off mains power to the PH-77.
ii. Check/disconnect cables to Direct input (R7), Ground posts (R5/R9) and Load post (R6).
iii. Connect the tonearm RCA connectors from the various cartridge/tonearm/turntable sources to the desired inputs
1 through to 3 (R8) at the rear of the PH-77 and ground posts (R5/R9).
iv. Select “Normal” by ensuring the Input switch (R3) as viewed from the rear, is set to the left.
v. Power the PH-77 ON via the rocker switch (R11).
To make switching between the multiple inputs the default selection setting (instead of the selection of EQ curves)
see Section 5 - Special System Setup.
When switching
between different
inputs, the countdown
of several seconds
allows for the PH-77 to
be optimally re-
configured
