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-EQ/post-fader for monitor or effect sends), as well as bus assign (L/R,
1/2, 3/4), mute and PFL switches. The PFL logic automatically shifts the L/R meters to the PFL signal
when any PFL button is pressed to assist in input gain adjustment and operates even when the channel
is muted. The mute circuitry squelches all sends from the channel, including all auxiliary sends and bus
sends.
Two “super” mic channels also have pad and polarity switches for those applications that require it, as
well as the standard channel functions. There are no line inputs on these channels. In addition to the
mic channels, there are two stereo (line level) channels for tape, CD or synth inputs. These have all the
standard channel functions except low-cut filters. AUX 5 and AUX 6 on these channels are
configured for stereo (AUX 5 is Left, AUX 6 is Right) and are pre-EQ/post-fader switchable.
There are four fully-assignable stereo returns with PFL and mute, two of which have treble and bass
controls. They can be used for effect returns or for additional stereo inputs. A dual function
headphone/control-room level control sets the volume of the headphones and the output level at the
control room output jacks. RCA type stereo tape inputs and outputs are provided, with sends to the
main L/R mix and the AUX 1 and 2 (monitor) mixes. A talkback mic input can be also be assigned to the
main mix or to AUX 1-4 for announcements or stage communication.
All bus summing amps are designed with discrete transistor circuitry for low noise operation. A unique
gain structure gives an additional 6 dB channel fader and summing amp headroom over other designs.
The Left, Right, and four sub-mix master outputs each have LED meters. They are calibrated for a 0 dB
reading at a +4 dBu output level. A balanced mono output (derived from the post fader Left and Right
outputs) has its own level control. Each channel, stereo return, and master AUX send has an overload
LED indicator that illuminates when the signal level is within 2 dB of clipping or when the PFL switch is
activated. Electronic muting of the AUX and the Left and Right outputs greatly reduce any turn on and
turn off transients.
