TANCHJIM SPACE II (Space 2) EQ app for Android
Contour EQ is a free, open-source Android app that writes the parametric EQ stored inside the TANCHJIM SPACE II, also written Space 2, and reads every send back. The EQ is written into the dongle itself, so it works in every app and on every device you plug it into.

Using Contour with the SPACE II
- Send a profile with HOLD TO SEND. Contour reads every band and the preamp back from the DAC, and shows ON DAC only if everything matches.
- Change FILTER, OUTPUT, GAIN, BALANCE or MIC GAIN on the DAC page. GAIN stays after unplugging; the SPACE II has no physical gain switch that would override it.
- The preamp goes from -30 to 0 dB in whole dB.
Everything else works the same on every DAC: How to use Contour.
Contour EQ and the Tanchjim app
Tanchjim's own app for the SPACE II sets the gain, the digital filter, the amp class, the microphone gain and the USB mode. Contour's DAC page has the same settings as FILTER, OUTPUT, GAIN and MIC GAIN, except the USB mode, and adds BALANCE. MIC GAIN is for the headset microphone on the 3.5 mm jack (CTIA), which the phone or computer sees as a USB microphone.
The WalkPlay catalog that devicePEQ uses lists the SPACE II's USB ID with 10 bands and -10 to +10 dB. Contour offers -12 to +12 dB, Q 0.1 to 10, and LOW PASS and HIGH PASS next to PEAK, LOW SHELF and HIGH SHELF. On a test rig the SPACE II played all five filter types as drawn, with cuts to -12 dB and boosts to +9 dB. Contour runs on the Android phone the dongle is plugged into, keeps your profiles in a library on the phone and needs no internet or account.
Questions about the SPACE II
Is there an EQ app for the Tanchjim Space 2 (SPACE II) on Android?
Yes. Contour EQ writes the SPACE II's 10-band EQ and preamp from an Android phone, reads every send back, and sets FILTER, OUTPUT, GAIN, BALANCE and MIC GAIN on its DAC page. It is free and open source (Apache 2.0). Tanchjim also has its own app for this DAC.
Which PEQ filters can I use on the SPACE II?
PEAK, LOW SHELF, HIGH SHELF, LOW PASS and HIGH PASS on 10 bands, from -12 to +12 dB and Q 0.1 to 10. Each filter type played as drawn on a test rig, with cuts to -12 dB and boosts to +9 dB.
Does the EQ work on a PC or an iPhone?
Yes. The EQ is stored in the SPACE II, so it plays on every device you plug the dongle into, PCs, Macs and iPhones included. You need an Android phone only to change it with Contour.
Can Contour update the SPACE II's firmware?
No. Contour does not update firmware. It writes the EQ and the preamp, and the five settings on the DAC page. It was tested on firmware 1.2.
