Footnotes

1) Secondary autoformers are used to adjust the amount of output gain.

All linestages with this feature have 6 adjustable gain positions.

2) Full Function remote features the following actions:

Volume, Balance, Mute, Phase, Home Theater Bypass, Input Selection and display off. All except for balance control are available from both the remote handset as well as front panel. Balance control is only available via the remote handset. Home Theater Bypass only on front panel.

3) Passive Mode

When using this feature, the signal is still utilizing the transformer coupling at both the inputs and outputs.
