Doepfer A-174-4 Joystick II Eurorack Module

JOYSTICK MODULE FOR EURORACK
 
Module A-174-4 generates several control voltages and a gate signal controlled by a spring-loaded X/Y cross potentiometer (so-called joy stick). The control voltages for X and Y are controlled by the X and Y position of the joystick in the usual way. The third control voltage Z is controlled by the rotation of the spring-loaded joystick knob. The gate signal is generated by a button at the center/top of the joystick knob. As an additional feature four control voltages are generated that are assigned to the quadrants of the Cartesian coordinate system. These quadrant voltages are derived from the X and Y voltages by means of a special algorithm.
 
For each joystick function the non-inverted signal (X, Y, Z) as well as the inverted signal (-X, -Y, -Z) is available. The generic joystick control voltages are bipolar and range from typ. -5V (lowest position) via 0V (center position) to typ. +5V (highest position). By means of the Offset controls OX, OY and OZ a variable voltage of up to 5V can be added to the generic voltages. That way it’s possible that the X, Y and Z outputs become pure positive (0…+10V instead of -5V…+5V). That’s necessary if e.g. VCAs have to be controlled, because VCAs require a pure positive control voltage. The offset voltages can be adjusted by means of three small potentiometers. When the control in question is fully CCW no offset is added and the “pure” control voltages X, -X, Y, -Y, Z and -Z without offset are generated. As soon as the offset control in question is moved clockwise up to +5V are added to the voltage in question. The offset voltages are also added to the inverting outputs. With max. offset the range of an inverted output becomes also pure positive (+10V…0V instead of +5V…-5V). These six voltages are output at the sockets “X+OX”, “-X+OX”, “Y+OY”, “-Y+OY”, “Z+OZ” and “-Z+OZ”. Each of these outputs is equipped with a dual color LED (red/yellow) that displays the present voltage and allows to distinguish between positive (red) and negative (yellow) voltages.
 
On top of this the four quadrant voltages Q1, Q2, Q3 and Q4 are calculated. A quadrant voltage becomes positive when the joystick is positioned in the quadrant in question. The absolute value of the voltage depends upon the position of the joystick lever in the quadrant. By means of the Overlap control overlapping of the voltages between the quadrants is attainable. When the overlap control is fully CCW there is no overlapping, i.e. only the control voltage of the currently addressed quadrant becomes positive, all others are zero. As overlap is increased the voltages overlap more and more. E.g. both outputs Q1 and Q2 become positive in the 12 o’clock position of the lever when the overlap control is turned up. The overlapping increases with the position of the Overlap control. We will explain this behaviour by means of a drawing shortly. Each quadrant output is equipped with a single color LED that displays the present voltage. The quadrant outputs provide only positive voltages in the range 0…+10V.

Features

  • Because of the construction height of the joystick (about 7 cm) the module cannot be installed into the cases A-100P6, A-100P9, A-100PMS6, A-100PMS9 and A-100PMS12 during transportation as the depth of the case cover is not sufficient. Into the base cases A-100PB and A-100PMB as well as in all other cases without cover the module can be installed without problems. We are about to find a solution for this problem (maybe deeper covers, but this requires also the modification of the cartons).
  • Because of the outreach of the lever in the extreme positions (fully left, right or down) it may be necessaey to arrange the adjoining modules in a different way or to install blind panels instead of modules. It depends upon the controls and sockets of the adjoining modules if that’s necessary.
  • In theory it’s possible to remove the return springs for the X and Y potentiometers. For this the joystick case has to be opened and the return springs removed by means of suitable tools. But because of the small friction it cannot be guaranteed that the lever will remain in the last position when it is released. That’s why we do not recommend this modification. Even the warranty is void if such a modification is carried out by the customer.
  • The joystick is a wear and tear part and is excluded from the warranty!
  • For this module the bus connection is located at the top because of the position of the joystick at the bottom (in contrast to most other A-100 modules with the bus connection at the bottom)!

RETURNS

The majority of items that we sell are covered by the Distance Selling Regulations in the UK which gives you 30 working days from receipt of the goods to cancel the contract and return them. There are some items which are not covered by the DSR's including Software and Hardware that includes Software needed for it's operation and Music items (Records, CD's DVD's and so on), (mainly in ear headphones and microphones).

If you do wish to return an item then please contact us and we'll give you the relevant information - buyers are responsible for the cost of shipping items back to us and also for ensuring they arrive back to us in good condition. If the returned items arrive back to us in a damaged state, or the product's original box/packaging is damaged, we reserve the right to deduct an amount from the refund in order to compensate for the damage. This amount will be decided by our staff after inspection of the items.

If you have received an item and it is faulty then please get in touch straight away. We will do our utmost to sort out any problem quickly and to your satisfaction.

Where items are faulty within 7 days from date of purchase, they will be classed as an out of box failure. These items will be collected, and replaced with an identical product (subject to availability of stock).

We may ask you to post small, low cost items, such as headphones, back to us.

Any items over 30 days old will need to be returned to either our service department, the manufacturer or their appointed agent for warranty repair. We will always advise you of the return address details that you should send the goods to where this is not our normal returns address.

SHIPPING

We use different couriers depending on the size, weight and value of your equipment: Royal Mail van for smaller stuff or UPS for larger boxes. If we're using a trackable service (Courier, Tracked, Special Delivery) then we send you a tracking number by email when we ship your order so you know what to expect.

Shipping services to Mexican and Russian addresses are currently unavailable.

For courier deliveries we use a next day service (Mon - Fri only) and they get there over 99% of the time but if you need a timed service for a before 12 or before 10AM delivery then just let us know and we'll get you a reasonable quote. We can also do Saturday deliveries (on items under 2kg only) if you need something for the weekend and you've left it to the last minute (as we all do sometimes)! Northern Ireland and other non-mainland locations might be a two day service and of course the Scottish Islands may be a bit longer again.

If you've any questions before you order, please call 0141 882 9900 (Option 2) between 10AM and 5PM (Mon-Fri)
