The ZERO 4001 has been designed for club, band, mobile and display applications and has been based upon the industry standard Zero 3000 and 4000 units. To these world famous units many additional features such as full dimming and remote control have been included by our research and development team to make the Zero 4001 the most comprehensive 3/4 channel effects controller available today.

The Zero 4001 features a fully automatic self-adjusting mains circuitry that allows it to operate on any supply voltage within the 100-240V 50-60Hz range. Utilising either 3 or 4 channels the Zero 4001 can control up to 5 Amps per channel but not exceeding the 15 Amps maximum total load for the unit. Each channel is capable of controlling any resistive load such as ordinary tungsten lighting and any inductive load such as neon, pinspots, properly ballasted fluorescent lamps and motorised effects in any combination.

5 amp, F-Fast, 5 x 20mm, ceramic, high rupture current (HRC) output fuses are provided for protection of each channel. The fuse holders are mounted on the back panel adjacent to the output sockets which are available in different output types, Bulgin, U-Ground and IEC.

On the front panel LED indicators monitor the status for Standby / Go, Power and additionally one monitor LED per channel shows the current channel levels.

The Standby mode can be selected from the front panel switch and can be overridden by an external control voltage of above 5 volts applied to the Remote Control Socket. The channel monitors provide continuous indication and operate even in Standby mode allowing you to "preview" your selected effect.

A Master Dimmer knob provides control of the overall level of all the channels allowing continuously variable intensity control from 0-100%.

4 Manual buttons are provided with the facility to flash a channel to the Master Dimmer level at any time, providing the unit is NOT in Standby.

4 Channel Selection switches select each channel to one of 6 modes. The Off, Half and Full modes control the static brightness of the desired channel. The Chase mode selects that the channel is to be included in the selected chase pattern. The Bass / Tenor / Alto / Treble mode selects the channel to Soundlite mode. Finally the Remote mode provides for external control from other Pulsar products via the rear panel Remote Control Socket.

Any of the channels selected to Chase will be affected by the Pattern select switch which allows choice of one of 11 patterns or allows the unit to Auto Change through the patterns (Flip-Flop and Flash are not included in Auto Change). Additionally a Direction select switch selects between Forward, Reverse, Bass direction change, Bounce/2, Bounce/4 modes or allows the unit to Auto change the direction.

The Slope control knob varies the chase from a crossfade (gentle fading) to a fast switching effect. A Constant / Bass Burst switch gives either a burst of chase steps for the duration of the bass beat or a fixed speed set by the Speed control of 10 minutes per step at Minimum to approximately 50 steps per second at the Maximum setting.

A 3/4 Channel Chase switch on the rear panel allows 3 or 4 channel chase patterns to be generated by the unit.

Whilst in Soundlite mode the advanced sound-to-light function separates the incoming audio signal into 4 audio bands and uses the volume in those bands to control the 4 channels. Automatic Volume Control (AVC) circuits adjust for overall changes in the music volume and tone. The Contrast control knob varies the sound-to-light effect from a crossfade (gentle fading) to a fast switching effect.

A full range Audio Input is provided via standard 1/4" stereo IN and THRU jack sockets mounted on the rear panel. They accept signals from a sound system in the range of 0.5-100V RMS with a input impedance of 33K ohms. The signal is not earthed directly within the unit but through a resistor. This serves to eliminate any possible earth loops and hence hum and interference on your sound equipment. Additionally there is an electronic circuit to enhance the separation between the sound-to-light channels to increase effectiveness.

When any channel is in Remote mode it can be controlled via the Remote Control 8-pin DIN socket on the back panel of the unit. It provides advanced control facilities over the Zero 4001 unit. This input is ideal for use with the Pulsar Litefoot footswitch. Technically the socket accepts six 0-10V channels where channel 6 can be used to override the Standby function on the front panel (channel 6>5v to GO). Channel 5 on the socket enables channels 1-4 to function in 2 modes as follows:

Mode 1 is selected when channel 5 is below 5 volts. It allows channels 1-4, when switched to Remote, to become dimmer control channels (0-10v = 0-Master Dimmer level).

Mode 2 is selected when channel 5 is above 5 volts. In this mode channel inputs 1-4 have special functions, including Standby/Go, Chase/Soundlite, Run/Step chase and chase Step. These features are present on the Pulsar LiteFoot.
