® SRC 4018 FC, 4026 FC and 4034 FC ® The SRC 4026 FC, 4034 FC and 4018 FC are versatile four-bus consoles in 18, 26 and 34 channel versions, built into road-worthy cases. Designed for sound reinforcement applications, they can also be used in multitrack recording. The standard channels feature discrete low-noise mic preamps with globally-switched 48V phantom power, low-cut filters, and four-band EQs. There are six auxiliary sends (four dedicated pre-EQ for mon- itor sends, two switchable pre-E

Channel Functions 1. Line Input 1 1/4" balanced (TRS) high-impedance input for high-level signals. The tip is the positive input, which should also be used for unbalanced inputs. This input is connected through a 10 dB pad to the Mic Input (#2). The two inputs cannot be used simultaneously. 2. Mic Input XLR balanced low-impedance channel input optimized for a microphone or other 2 low-level source. Pin 2 is the positive input. Because of the wide range of gain adjustment, signal levels as

AUX 5/AUX 6 Adjusts the level of the channel signal that is added to the corresponding AUX mix. These are selectable Pre- or Post-EQ Fader (#12) on all channels, and are configured in stereo (AUX 5=L, AUX 6=R) on the two stereo channels. They can be used as a stereo pair to drive stereo effect units. (See #14) 12. Pre/Post

21. Pad Attenuates the input signal by 10 dB. This will increase the dynamic range to accommodate a higher input level before clipping which may be necessary when close miking loud guitar amplifiers or drum kits. 22. Polarity Reverses the polarity of the input signal. This will compensate for an out-of-phase input that would otherwise cause frequency cancellations in the mix. (Often needed for drum mics where both sides of the drum head are picked up in multiple microphone situations.) 23

29. LED Meters 29 Six 12-segment LED arrays monitor the levels of the sub mixes and the main L-R outputs. The 0 dB reference level corresponds to +4 dBu. The L-R meter array is also used for PFL metering. (See #18, 28 and 33) 30. Sub Pan Sets the position of the sub mix in the L-R stereo field. 31. Sub PFL LED Illuminates when the Sub PFL switch (#33) is depressed to indi- cate that this signal has been assigned to the PFL mix. 32. Sub Mute Mutes the sub mix signal to the sub output and t

39. Tape Out Level Sets the level of the main left and right stereo signal sent to the tape output jack. It is post master fader. 40. Tape Input/Output One half of this stereo RCA phono jack provides a 40 signal for the recording inputs of a stereo tape deck, with an amplitude set by the Tape Output Level 39 control (#39). The other half accepts a stereo input (nominally -10 dBu) from the output of a tape deck or CD player. 41 Caution: The tape output signal includes the tape input si

APPLICATIONS (Cont.) RECORDING: The connections for recording are very similar to those of the sound reinforcement section above with the following differences: 1. For recording tracks, connect the input sources as described above and use the sub mix sends to feed the recorder's inputs. For mixdown, the multitrack recorder's outputs are connected to the line inputs and assigned to the L/R mix. 2. Connect the Sub outputs (the Left and Right outputs are included in this group if they are not in
