21U Studio Case

The Studio Case is the first eurorack case in the SynthRacks line and a fantastic addition to any studio; home or professional. The case is available with a selection of variables to help customise the case to your needs. Including, horizontal pitch, power supplies and fixing components. The case is made from solid wood and finished with danish oil for a great finish and to protect the wood. The inner panels are black, which works as a nice contrast to the solid wood.

At the back of the case, there is a continuous air vent and a utility cut-out (60mm x 90mm) in the rear panel which is blanked off with 2 removable and interchangeable panels that simply screw into the rear panel covering the cutout. The main purpose of the cutout is to allow for easy access to install an alternative power supply. We can supply a variety of panels including a plate housing an unwired IEC C14 male connector (a kettle lead). This will occupy half of the utility cut out. The second half can remain as a vented blank panel or we can supply a plate with a variety of handy pre-punched panels.

POWER

We have 2 options available for our cases over 9U in size. The TipTop Audio Zeus Power System & the Konstant Lab HammerPWR. There are more details on both below. We can fit both systems in your case if you decide to go for either of these power options

TipTop Audio

The TipTop Audio system provides quality Eurorack power for your system. If you purchase your case with the TipTop Audio Zeus Studio Bus system, you will be provided.

• Zeus Studio Bus board – one for each row of modules.
• Zeuss Access Switch.
• Cincon-TTA Power Supply.

There is lots of information and additional details in the TipTop Audio Zeus Studio Bus manual. The manual is well worth reading to understand the system, although a great deal of the information is about installing the power in your case. Of course, if you order a SynthRacks case with a power system, we will install it for you. If you are starting to build up your eurorack system, we can supply a single Zeus Studio Bus board, to which you can add additional boards as your system builds up (please get in touch to enquire about pricing). The case will be pre-drilled to accept new boards – if you get these from SynthRacks, we will supply all the necessary hardware (the standoffs/spacers) and hook-up wires.

The Zeus Studio Bus board offers a total of 16 module connectors: 14 of them are 16-pin headers for connecting Eurorack modules and two of the connectors are for Analogue Systems modules. The additional 5V voltage needed by some modules is being generated internally by the Zeus Studio Bus. Three LEDs show the active voltages 12V, -12V and 5V. The maximal current per bus board is 1250mA at 12V, 800mA at -12V and 300mA at 5V. Tiptop Audio recommend the use of a powerful external power supply with 4.6A for providing up to three Zeus Studio Busses with power. The Cincon power supply will be supplied with a 13amp IEE lead (kettle style lead). If you are buying outside of the UK you will need to supply your own lead to connect the power to the mains.

Note: Cincon switching power supply works with 110v to 230v.

Konstant Lab

HammerPWR SET – includes a small 100W power board (zero HP) (+12V / 5A, -12V / 2.5A, +5V / 2A), a power inlet panel with switch, four filtered bus boards – each of them has 18 output headers (6 filtered and 12 direct) which ensures that you will be able to power up quite a lot of modules, 120W Meanwell power brick, wires, spacers, and screws.

HammerPWR is a small but powerful, low-weight PSU solution. You can mount it into your synth case without sacrificing any HP. HammerPWR is safely supplied from an external DC power brick (19-24V).

The Filtered Bus Board is a low-profile bus board with extra filtered output headers. The bus board contains 18 output headers. 12 direct headers and 6 filtered headers with LC filters. Filtered headers are specially dedicated to feed analog modules that are sensitive/susceptible to power quality. Filters reject noise caused by PSU and digital modules by 70%. Each power rail is protected against overvoltage so your modules and system are safe under all conditions. 90% of the bus board area has only 11mm with inserted connectors. This feature makes the Filtered Bus Board an ideal power distribution solution for skiff cases where depth is a concern.

Dimensions – 43 × 30 × 6 cm

Weight – 1.8kg

Power – 100W

Output – +12V / 5000mA, -12V / 2500mA, +5V / 2000mA

Typical output ripple noise – under 15mVpp / 20MHz BW

Number of headers –  Total 76 output shrouded headers

Other features

• Overvoltage protection on PSU also on each bus board – keep your modules safe
• High-quality shock-resistant ‘Push to Connect’ terminals
• Unique LC filtering circuits
• LEDs indicate the presence of voltage and voltage drop
• Easy for montage and connection
• Meanwell power brick with a worldwide input range
• All parts for PSU system included (PSU, Powerbrick, Busboards, power cord, Inlet with switch, wires, screws, spacers, fixing stripes…)

MODULE FIXINGS

SynthRacks Eurorack Cases are all set up to accept M3 machine screws. We would recommend the square sliding nuts and with each case, you will be supplied with the following:

• 84HP cases – 40 M3 sliding square nuts per 3U frame.
• 104HP cases – 50 M3 sliding square nuts per 3U frame.
• 126HP cases – 60 M3 sliding square nuts per 3U frame.

However, you can specify – as an optional extra – that your case is fitted with threaded rails instead of the sliding nuts. (Note: threaded strips will come in two parts, in cases larger than 126HP)

Each 3U will also be provided with M3 machine screws, which are suitable to use with the sliding nuts or the threaded rails. We keep a stock of all fixings so additional M3 machine screws and nuts can be purchased as required.

Sliding nuts are more economical and should allow you – by loosening the screws – to slide a module along the rail to reposition it without taking it out of the case. They will also ensure that the modules can butt up neatly to each other, which otherwise may not be possible with threaded rails, due to different manufacturer tolerances of the module face panel.

Either way, not a matter to dwell on for too long, as the frame can be removed from the case without much effort and additional nuts or threaded rails can be inserted.

Delivery

All our cases are handmade. If you place an order with us you can expect your case to take about 3-4 weeks before delivery. We will be in contact throughout the process to confirm requirements and communicate delivery dates.
