Manufacturer's description
- Connects to IO module to provide 24 balanced audio outputs
- Connects to Xcelon mixer and expanders for 12 stereo direct outputs
- D-Sub connectors accept 8-channel balanced audio snakes
- Low-noise signal path with isolated channel circuitry
Direct multi-channel expansion
DB25 is part of Boredbrain’s direct multi-channel audio series of modules, which interconnect to provide a multitude of audio outputs to Eurorack systems. DB25 can interface with the IO module and/or Xcelon mixer for up to 24 balanced audio outputs.
Flexible Interconnection
On the front of the module are three 25-pin D-Sub connectors, which each output eight channels of balanced line-level audio for a total of 24 outputs. The channel numbers next to each DB25 connector (1-8, 9-16, 17-24) correspond to those on the rear input ports.
NOTE: The pin-out for these connectors is consistent with standard DB25 balanced audio snakes like the Hosa DTP-800 series.
The four input ports on the back of the module (INPUT 1-6, 7-12, 13-18, 19-24) accept signals from compatible Boredbrain modules using the supplied 8-pin ribbon cables. When connected to the IO module, these ports accept groups of six individual input signals. Similarly, when connected to the Xcelon mixer or XP3 channel expander, these ports accept banks of three stereo mixer channels for direct output. The connections to these ports can be mixed and matched in any order, and both the PRE and POST direct outputs for a bank of channels (Xcelon) can be used simultaneously.
Balanced Audio Output
Balanced audio is essential in pro audio applications due to its immunity to noise introduced in long cable runs. Audio signals in this format are commonly used with pro audio interfaces, mixers, patchbays and live sound equipment.
The module’s three DB25 connectors output differential signals scaled to +4 dBu, which can drive long cable runs with high capacitive loads. The compact layout is made possible by using high performance balanced line driver ICs rather than much larger isolation transformers.
These differential or “balanced” signals are the key to noise rejection. Prior to signal output, a duplicate is made with an inverted polarity. The original signal, SIGNAL +, is carried on one wire, while the inverted signal, SIGNAL –, is carried on another. At the balanced input, the inverted signal is re-inverted and combined with the original signal. Because any noise picked up across the cable affects both signals equally, it undergoes phase cancellation and is removed from the FINAL SIGNAL.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK, 'next working day' shipping is free if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.
Shipping to mainland EU typically costs between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of DPD, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we aim to dispatch the same working day if we get the order before 16:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.
Saturday/Sunday shipping
If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.
International shipping times
Since April 2020, the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer. There is absolutely nothing we can do about this, unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
