Venue 1 is the main venue of the students union. It is designed to be a multipurpose venue, and as such can hold bops, theatre productions, Live TV sports screenings, boxing, and debates.

Location

The venue is on the ground floor of the union. It serves as home to the Beer Bar and Poison Bar, the Raised Seating Area and Seating Block, and the Stage.

Attached to the venue are the Ents Cupboard and Green Room, whilst the Projection Box looks out over the floor.

Lighting

Venue 1 has three main rigging areas: the Octagon, the Stage Rig and the LX Bars, numbered LX1 (nearest the stage), LX2 and LX3 (farthest from stage) as well as "Left" and "Right". At times, the space frame above the front of the octagon is used for rigging lights; this is referred to as LX2.5.

There are also 2 side projectors mounted on the octagon, pointing at screens above the speaker stacks on either side of stage, and a projector pointing at a roll-down screen which fills the entire proscenium arch. These are all linked to Entsputer, while the latter is also linked to a Freeview tuner.

Equipment-wise, the venue has

Sound

The FOH sound system in the venue is a Martin Audio Wavefront series system. The two stacks of speakers, one on either side of the stage, each comprise;

Total power handling of the speakers is ~5.6kW AES, ~22.5kW peak.

Notes;

  • The subs are the original WSX model with the original RCF L18P300 drivers rated (by Martin) at 600W AES/2.4kW peak. They are NOT the current WSXa model offered by Martin, which have newer drivers rated at 1kW AES.
  • Front-loaded horn subwoofers are a poor choice for indoor use, for use in stacks of less than 4x & for use with an audience closer than 12 feet. Thus sub coverage in the venue is poor, whilst sound pollution outside the venue is high.
  • In order to properly cover the width of the venue with mid-high, especially for audience members close to the stage, the W8C cabinets need to be positioned & splayed correctly. Each W8C cabinet has a 55° horizontal coverage. A 40° splay between 2x W8C cabinets (26cm/10" between cabinet front covers) provides a flat 95° horizontal coverage, which is sufficient to cover the width of the venue when the cabinets are positioned correctly. A smaller splay will not only reduce the horizontal coverage, but also boost the forward output levels - the result being that the centre of the venue is too quiet whilst the areas in front of the speakers is too loud. Essentially, the inner W8C on top of each stack of subs should be rotated 62.5° inwards (from the perpendicular pointing straight out of the subs toward the rear wall of the venue), whilst the outer W8C on top of each stack should be rotated 12.5° outwards. However in reality the surface area of the top of the subs isn't enough to actually rotate the W8C that much without them toppling off...

The venue amp rack contains;

The MX5 units are responsible for taking a full range line-level signal (such as that from a DJ mixer or sound desk) & splitting it into 4x frequency bands (sub, low, mid, high) each of which is output to the respective amp. The MX5's also apply the necessary delays (due to different horn lengths of the different drivers) & have (internally set) limiters to ensure that (even when the AVC2 is bypassed) the speakers can not be damaged by excessive power. The MX5's are mono units, hence why there are 2x of them - one handles the left channel, the other handles the right channel.

The Crest, C-Audio & Crown amps all run in a stero configuration (eg the Crest powers the left stack's W8C compression drivers from one of its channels & the right stack's W8C compression drivers from its other channel). However the JBL amps each power one stack's WSX subwoofers - the top unit powers the left stack's subs whilst the bottom unit powers the right stack's subs. On both units channel 1 powers the top sub in its respective stack, whilst channel 2 powers the bottom 2 subs in its respective stack.

The processing rack on top of the amp rack contains;
