Goodwood Audio Isolator TX
Isolators Purpose
We get asked all the time how to start experimenting with a Wet Dry or Wet Dry Wet style rig. To fully commit takes a lot of patience, time and honestly, some hardware. If you aren't sure this is the way you want to do, experiment with as little as possible first! Add Isolator and instantly get a mute-able, isolated dry output to add to your series pedalboard!
Ground Lift and Phase Control: You can add an isolation transformer to the Dry (B.out) Output to correct against ground loops and phase issues between amps.
If this is something you find confusing (do I need it or don't I), a good way to look at this is if you want to use 2 amps at a gig, get one transformer. If you're happy to drop to one amp if you get a ground loop / phase issue at a gig, don't get any transformers. If you're happy to drop to two amps at a gig if you get a ground loop / phase issue, get one transformer.
You need one less transformer than the amount of amps you want to use while playing.
This doesn't necessarily apply to amp simulators as they typically send to a DI which has ground lift built in (double check your DI to make sure). Therefore you wouldn't necessarily need a transformer in this box as well as the DI transformer.
Manual & Specs
Isolator at its core is a buffered split with a few extras added in for good measure. The main goal here is to take your dry effects (overdrives, fuzz, distortion etc) and send them to your modulation / wet effects (as normal) AND to a dedicated dry amp.
This allows for your core tone (your dry effects) to be heard clearly without being muddied up by delays, reverbs and other glorious noise makers that we as guitarists tend to overuse.
Instantly mute your dry amp with Isolator using your midi controllers amp switching jacks, an RMT or any other normally open momentary footswitch you have laying around!
Input
Plug your last dry effect in here. Your signal will now be split to two places:
Out A - Send this to your first wet effects
Out B - Send this to your dry amp. This is the output that is both mute-able and isolated with ground lift and phase pushbuttons.
Outputs
There are two outputs on Isolator:
1. A Output - This is the output you use to send signal to your first wet effect. This output is not affected by the dry mute.
2. B Output - This is the output that you use to send signal to your dry amp. This output can be muted and is connected to the ground lift and phase pushbuttons (it is an isolated output).
RMT Jack
The RMT jack on Isolator can be used to mute the dry output remotely. You can connect a TRS cable and a Goodwood Audio RMT pedal to control this dry mute or connect your midi controllers amp switching jack.
If you decide to use your midi controllers amp switching jacks, or a standard momentary switch, you can use a TS / mono patch cable. No need for TRS.
Pushbuttons
There are three pushbuttons on Isolator:
a. TX (if transformer added) - Use this to lift the ground on the B output. This is only needed if you hear a hum in your multi-amp setup. If you have a ground loop between amps, this button should get rid of it.
b. 180 (if transformer added) - Use this if your two amps are out of phase with each other. If out of phase, they will most likely sound 'honky' and have a reduced bottom end. If you unplug one amp and the bottom end returns / honk is gone, you are most likely out of phase. Push this button to correct that.
c. Mute B - If not using the RMT jack, use this pushbutton to mute the B output.
Note: If the RMT jack is plugged in and being used, the RMT will override the pushbutton state.
These are designed to last and come with a 2 year warranty!
All Isolators are made with high quality, durable components.
IMPORTANT - Use only 9vDC centre negative plug to power!
Current Draw/Power: 75mA, Center Neg 2.1mm
Isolator Box Dimensions: 113mm x 60mm x 31mm
Input Impedance: 1Meg
Output Impedances: 500ohms
Warranty & Returns
All New products are covered by the manufacturers new warranty. Please check their website for the length of warranty and warranty conditions. If an item you receive is faulty get in touch with us ASAP. Second Hand products come with a 4 week warranty from us. If there is an issue let us know ASAP! This covers normal use and does not cover accidental damage, misuse, wrong power plugged into it, modding, water damage or any other damage caused by mistreatment. Just treat it nice and all will be good!
Shipping
We send A LOT of packages every week so don't worry about the shipping side of things!
We've never lost a thing and your awesome new gear will be packed up really well to avoid any damage in transit.
If your order comes in before 2pm we will ship it same day. Most of the time we pack things up all the way to 4pm so just call if you need it to leave same day after 2pm.
We ship mainly with Australia Post but may use a courier depending on location and size of the package.
Free Post ships with Australia Post standard and expected shipping times are between 4-6 business days depending on location. It will be longer to outside of metro and rural areas.
Express Post will usually be with you next business day in metro areas of QLD, NSW, SA, VIC and TAS. WA will take 2 days to metro and extra days after that to out side metro and rural areas.
Everything we ship has a tracking number with the exception of some power cables and smaller envelope packages. You will be emailed tracking once your order has been shipped!
