6 EURODESK SX3282 User Manual 2. SX3282 Overview 2.1 Architecture The SX3282 is a conventional split console. By this we mean that the inputs and outputs occupy separate areas of the board. This makes for easier visualization of signal path compared to an in-line design, which uses combined input/output channels. The main section on the right hand side handles all the outputs (as well as 4 stereo aux returns and a 2-track tape input), input channels are located on the left. The configuration is 32 into 8 into 2. This means that there are 32 channel inputs in total (there are 24 mono and 4 stereo channels), assignable to 8 subgroup buses (plus the main mix) which in turn may be blended into the main mix stereo output. The subgroups (configurable as stereo pairs if required) are provided for connecting to a multitrack tape recorder, or for use as a mixing aid during mix-down or during a live concert. Every channel, and two out of four stereo aux returns included in the SX3282, can access any or all of these subgroups or the main mix directly, via comprehensive routing matrices. All channels also have access to eight aux send buses. Each channel can access 6 aux sends simultaneously. For each channel the 8 aux sends are switchable between two configurations: six pre- and two post-, or six post- and two pre-fader, for live or studio operating environments respectively. Input channels The first 24 input channels are mono, with a choice of balanced mic (XLR, +48 V phantom power switchable) or line (¼" TRS) inputs, both with exceptional gain architecture. A further 8 line inputs are configured as 4 stereo input channels, accepting all line level signals. Every channel has mute, Solo/PFL and comprehensive EQ. A high-quality 60 mm fader feeds the main mix and/or subgroup buses via subgroup- and mix-assign switches. A constant-power channel Pan also selects between odd and even-numbered subgroup buses. Subgroups For ease and flexibility of mixing, eight mono subgroups with Pan and Solo are provided. Each has its own individual output, and each may also be assigned to the main mix. Aux sends There are eight master aux send outputs, each with Solo and Gain. Aux returns Four line-level stereo aux returns, each with Solo and Gain, are located above the subgroup faders. Note that AUX RETURNS 1 and 2 are assignable to any mix bus. Stereo aux returns At the main section's top end (middle) you will find four stereo aux returns, each with Solo and Level control. AUX RETURN 3 and 4 are hard-wired to the main mix, while AUX RETURNS 1 and 2 can be switched to either main mix or the subgroups and therefore are equipped with a BALANCE control. Main mix output / additional features Main mix output level is being controlled via a pair of high-quality 60 mm faders. The main section also includes an assignable headphones output with LEVEL, a 2-track tape return assignable to the control room/monitors, and a solo output, adjustable for audition level and switchable between the solo and PFL function. The monitor (or control room) output is independently adjustable for level, and the integral talkback mic is routable to 6 of the 8 aux buses, i.e. all possible pre-fader (cue) sends. A BNC connector is provided for a gooseneck lamp for those dark winter's night mixes. Inserts Mono channels, subgroups and the main mix all have insert points for patching in dynamics processors etc. 2.2 Metering All input channels have signal and overload LEDs, while the L and R output has a pair of 12 digit bargraph meters. The main mix (L/R) meters also have clip LEDs (+28/22 dB: balanced/unbalanced), and double up as mono PFL or stereo solo meters, or 2-track return meters (in general, what you hear is what you see). During Solo/PFL only the main mix bargraph meters illuminate. ◊ The master clip LEDs (+22 dBu) should never be allowed to illuminate. If they do, reduce either the MAIN MIX fader or the group(s) and/or channel fader(s), or (as a last resort) the channel input gain(s). Maybe it's time to do a round of PFL metering. ◊ In Solo/PFL mode a 0 dB meter reading matches an internal operating level of 0 dBu (0.775 V). However, when looking at the mix, 0 dB is referenced to +4 dBu, the 2-track operating level. I.e. if only one signal is present in the main mix bus, soloing that signal will cause the meter reading to increase by +4 dB.
