CV 20 includes those features most-desired by touring and permanent installation engineers. Full-VCA control is provided, not only on input channels but also on group masters (aux masters in fader reverse mode) and L/R and Mono masters for maximum control of complex mixes. Four band sweep able EQ with Q control on the mids and a variable High Pass Filter are provided on all mono inputs. 12 auxiliary sends and 8 sub groups are standard on all CV 20 models with fader reverse functionality for easy use as a monitor console. CV 20 consoles are supplied with either 24, 32, 40, 48 or 56 mono input channels, plus 8 full stereo input channels. Basic configurations for all consoles included 12 auxes, 8 subgroups, Left/Right/Center/Mono with full metering. Also provided is an 11x4 matrix, full dynamics which can be either routed to the subgroup and L/R/M buses or auxiliary masters, true LCR panning on mono inputs and subgroups and full metering on all main outputs (Auxes, Subgroups, L/R/M buses). CV 20 also comes stock with a total of 16 mute groups, 136 mute scenes and 128 VCA assignment scenes. One Internal Field replaceable, power factor corrected, universal power supply is standard on all CV 20 frames. An optional expansion system enables the addition of a second internal PSU and a 3rd external PSU. Also provided is an optional meter bridge with analog metering of all main outputs (VU), bus link I/O module for linking multiple CV 20 frames and modules to deal with digital audio transport. 8 sub groups 8 VCA masters Semi-modular inputs in blocks of 8 Inserts on all mono and Main outputs Optional Meter Bridge to monitor outputs in VU LED bar graph metering on all inputs and outputs True LCR panning from mono inputs and subgroups Optional Bus Link modules to link 2 consoles together Optional Digital audio transport modules Frames sizes available 24, 32, 40, 48 and 56 mono + 8 stereo Flexible design allowing FOH, Monitors or Monitors from FOH applications Fader reverse function allows fader and VCA control on aux outputs 12 auxes with flexible configurations (1-4 mono, 5-10 switch able between mono and stereo, 11 & 12 stereo with pre and post switching in the same configuration) Full dynamics on all main outputs (L/R/M and subgroups) that are routable to the Aux masters 16 mute groups, 136 mute scenes and 128 VCA assignment scenes with easy editing, snapshot automation and MIDI/RS485 control USB Link for saving settings via a jump drive or external control via Crest Audio’s NexSys® audio control software package Direct outs on all inputs (Switch able between pre and post fader from the top of the surface) C V 2 0 WELCOME TO THE CV-20 Mono input module blocks are made up of assemblies of 8 channels. Each channel includes switches for; 48 volt phantom power, -25 dB pad and polarity in addition to a high quality mic pre-amp that features high headroom, high slew rate and excellent CMRR performance. Also provided on all mono inputs is a high-pass filter that is variable between 20 and 400 Hz. Separate . inch jacks are provided for a pre-EQ balanced send and a balanced return at a nominal level of +4 dBu. Insert on/off switching is also provided to allow permanent patching. Four-band EQ is provided with sweep able high and low frequency points and selection between shelving and peak, full parametric control on the mid bands with frequency sweeps and Q control. The entire EQ circuit can be bypassed by disengaging the EQ ON Switch. 12 auxiliary sends are divided into 3 versatile sets. 1-4 being fixed mono sends with their own pre/post switch. 4-10 are switch able between dual mono and stereo with pre/post switches per pair and 11 & 12 are fixed stereo with pre and post selection for crucial “In ear monitoring” applications. The default “pre” selection is pre-fader/post EQ, but internal options allow this election to be changed to pre-EQ. C0501909BB MONO INPUT MODULE 8 Subgroups are also provided for conventional groupings of the inputs via 8 individual assignment switches. Stereo panning between group pairs can also be achieved by selecting the “PAN ON” Switch. Left/Right and Mono routing is done by pressing either the L-R or M/C switches. A separate LCR switch is provided. This allows panning between the Left, Mono and Right buses for LCR applications. A high quality 100 mm fader is standard on all inputs with 10 dB of gain when in the full up position. Also provided is full VCA control of the fader via a soft VCA assignment and mute control locally or via grouping (see master control block). The Solo switch allows PFL or AFL monitoring of the channel selected from the master section. The Solo Switch is also part of the VCA assignment (see master section). Other monitoring functions include a 5-segment bar graph meter for maximum visibility. MONO INPUT MODULE CV 20 Eight full-time stereo channels are provided standard on all CV™ 20 frame packages with the ability to add more modules on custom frame packages. The stereo mod...
