The mid-sized option in Teenage Engineering's innovative POM range, the 170 is designed as an introduction to modular synthesis. A simple DIY build in IKEA-style flat-pack format.

Supplier notes:
POM-170 is a home-build analogue monophonic synthesizer with built-in programmable sequencer. A complete kit with powder coated chassis, keyboard, oscillator, filter, envelope, LFO, VCA, speakerbox, power distro, powerpack, a screwdriver, 8 patch cables, and an illustrated build guide.

Each kit comes with all of the parts needed to build the project. Included in these flat packed synthesizers are everything from a powder coated aluminium chassis to an illustrated build guide with instructions and bend angles. When bending is complete, move on to mount the modules, snap the wire connectors and finalise your build with knobs and rubber feet. Remember, think twice and double-check the angles before bending.

Warning: Make sure to remove the batteries from the battery holder before connecting the DC-plug to the external AC / DC adapter.

Use separate battery charger to charge re-chargeable batteries.

Note: There is no power supply included. If you want to run the units on wall power you need an adapter with the following specifications (sold separately):
AC / DC adapter
12V, min 1A (12 watt)
Polarity: center negative
Plug: 4.75 / 1.7mm

MEET THE MODULES
M-1
square
square oscillator
Rich in odd harmonics, the square wave oscillator is great for hollow basses and screaming leads. The pulse width modulation (pwm) input makes it possible to generate
a faux two oscillator detune sound.

M-4
filter
low pass filter
Shape your sound with the 24db / oct low pass filter. Get lost in space while tweaking the resonance and frequency pots.

M-5
env
envelope
A classic. Attack, decay, sustain and release. Give your sonic creation the contour it deserves. Triggered by any signal that crosses the two volt threshold.

M-6
vca
voltage control amplifier
Automate your volume! Feed it control voltage and your signal will adapt accordingly. Best friends with the envelope for classic configurations, and your oscillator in wired configurations

M-10
lfo
low frequency oscillator
Generating both square as well as triangle waves, the low frequency oscillator is the perfect tool to spice up your patches. Great in everything from automated filter sweeps to syncing the clocks.

M-11
speaker
amplifier+speaker bellow
Cables goes in, sounds come out. Show off your amazing patch to the rest of the world. Let them hear it.
Warning: never connect headphones directly to the outputs! You can damage your ears and your headphones.

M-16
keyboard
keyboard+sequencer
Keyboard with individual tuneable keys and a programmable step sequencer.
