Lighting Equipment Notes

AutoYoke

The City Theatrical AutoYoke (new for the 2000-2001 season) is permanently mounted just SR of center in the second beam. Getting it there was a bit awkward but it works very nice. The upstage shot is somewhat limited due to the nature of the theatre. Our AutoYoke is equipped with AutoIris but not AutoFocus.

Our AutoYoke is setup for 8-bit operation and requires five DMX channels - Pan, Tilt, Iris, Focus(unused), Setup(rarely needed). We suggest you plan for three console channels Pan, Tilt and Iris.

I-Cue

The Rosco I-Cues can be set for either 8 bit or 16 bit operation. The Play House does not currently own a console capable of 16 bit control. The unit is supplied 24vdc and DMX from scroller style power supply and control cable.

• 8 bit mode
  • Channel 1 - Pan - 0.9° resolution
  • Channel 2 - Tilt - 0.225° resolution
• 16 bit mode
  • Channel 1 - Pan Course - 0.9° resolution
  • Channel 2 - Pan Fine - 0.228° resolution
  • Channel 3 - Tilt Course - 0.225° resolution
  • Channel 4 - Tilt Fine - 0.028° resolution

We have found the I-Cues to be quite a bit quieter than the ElipScans and as such they are the only option for the Baxter Stage.

ElipScan

The Meteor ElipScans require a total of five DMX channels Pan, Tilt, Pan Speed, Tilt Speed and Relay(unused). One oftens plan uses only three console channels - Pan, Tilt and combined speed. The speed channels are of little use but should be set to FULL for the unit to work properly. The ElipScan makes a high pitched whine that makes them inappropriate for the Baxter Stage.

Double Gobo Rotator

The Rosco Double Gobo Rotators can be controlled via MFX adapters or via the DMX control box. When using the MFX control you will have single direction control of one of the motors. When using the DMX DC controller you will have bi-directional control of both motors.

Rosco advises that the max cable length from the DMX control box to the rotator be 50 feet.

Indexing Double Rotator

The DHA Indexing Double Rotator is controlled directly via DMX. There are several modes of operation.

Mode 1 emulates the operation of standard double gobo rotators with the DMX DC Controller but with the added functionality of indexing. The rotation speed of each gobo is controlled by two channels of DMX, channel 1 controlling the forward rotation and channel 2 controlling reverse rotation. Setting both channels to the same non-zero level will stop the gobo in an index position represented by the channel level -i.e.both channels at 1% level will stop the gobo at 0° rotation;both channels at 50% will stop the gobo at 180 °rotation. Channels 3 and 4 are used for the second gobo.

Mode 2 provides basic control of rotation speed/direction and index position similar to that used by many moving lights, using just one DMX channel for each gobo.

All indexing will take place at approximately 5RPM.

Mode 3 uses 3 DMX channels for each gobo and allows for 16 bit indexing which is accurate to 0.1°(see note*). This mode also allows for independent control of direction and speed of indexing.

Indexing will take place at the speed and direction set by channel 1 (or channel 4 for gobo 2)unless it is set to zero,in which case indexing will take place at appr x.5 rpm.

*NOTE:The gears that are used on the Indexer have a small amount of backlash which is used for heat expansion,and this can affect the accuracy of the Indexer.Accuracy can be maintained if the lighting console is programmed so that indexing always occurs in the same direction.

Diversitronics Strobe

The Diversitronics strobe has an attached control box with dials for intensity and rate. The unit is approximately 6" x 6" x 15".

Diversitronics Ellipsoidal Strobe Module (ESM-DMX-S4 for ETC Source 4)

The Diversitronics ESM-DMX-S4 is a replacement cap for the ETC Source Four. The unit requires two DMX channels - Intensity and Rate. We do NOT own an analog controller. The unit must be powered with direct AC not from a dimmer or a non-dim. A max of two modules per 15amp circuit. The flash rate is variable from 15/sec to 15/min. Color temperature: 5600K; 22 joules/flash max.

Wybron Forerunner Color Scrollers

The Wybron Forerunner Color Scollers use a 16 color scroll. There is not an option for a partial scroll. We currently have three sets of "stock" scrolls.

Wybron ColorRam Scrollers

These are original Wybron ColorRam scrollers NOT ColorRam II. Maximum of 24 colors in a scroll. Due to fan noise these are NOT recommended for the Baxter Stage.
