Tape Input
The Tape Input is a 1/4" balanced TRS connector which will accept either -10 dBV or +4 dBu, depending on the setting of the +4/-10 switch (see next section). The Tape Input is the normal source of the Monitor path. However, when the CHAN/MON REVERSE switch is pressed, the Tape Input is switched over to the Channel path (see section 6.0.5). Connect the outputs of your balanced or unbalanced multitrack tape machine here; however, this jack is normally intended for use with unbalanced inputs, since the ELCO-type connector provides an easier way of connecting balanced tape inputs and outputs.
If you don’t use all the Tape Inputs, unused jacks may also be connected to the outputs of synthesizers or effects devices.
+4/-10 Switch
The +4/-10 switch adjusts the input level of the Tape In path. Its setting affects both the 1/4" jack and the ELCO balanced connector. When pressed in, the -10 setting is selected. When out, the +4 setting is selected. When using equipment with a high output, switch this to the +4 setting. When the source has a low signal, select the -10 setting.
Tape Send (Direct Output)
The Tape Send output is an unbalanced 1/4" connector which provides either a direct output of the post-fader channel signal or a Group Out signal, as set by the DIR switch on the top panel of each channel strip. It is set to give a -10 dBV output. Connect this to the track inputs of your multitrack tape recorder, if you aren’t using the ELCO connectors for balanced operation.
Insert
The INSERT connector is a TRS 1/4" jack which consists of an insert send (the tip of the TRS plug) and an insert return (the ring of a TRS plug), and is used to insert an outboard effects device (such as a compressor, EQ, or chorus) directly into the signal path of only the channel it is connected to. A special Y-cable consisting of a TRS 1/4" plug on one end and two mono 1/4" plugs on the other end is required.
