Introduction
The RetroTINK-2X MINI (hereinafter, “MINI”) is a device capable of line-doubling standard
definition sources from composite and S-Video signals from retro consoles to 480p/576p,
which can be readily accepted by modern displays. All processing are essentially “zero added
lag” to preserve the original gaming experience.
The MINI supports multi-region decoding of NTSC/PAL/PAL-60 and other encoded formats.

Advanced Features
COMB Switch
The MINI’s comb switch is primarily used to toggle between a notch style composite decoder
(Retro) or an automatic 5-line comb filter (Auto) mode.
Many older off-spec systems such as the NES will look better with a notch style filter. Other
systems such as the PC Engine may look better in (Auto) due to their higher quality
composite output.
The ‘Auto’ setting also engages a high frequency luma filter in S-Video mode. This reduces
the luma sharpness slightly but eliminates chroma cross-talk noise. This setting is mainly
useful for PAL/PAL-60 N64 users as chroma noise may be a problem unless you are using
shielded S-Video cables. In the case of the N64, since the image is already blurry, the slight
loss of luma resolution is negligible.
Multiple Inputs
You can connect both composite and S-Video inputs to the MINI at the same time. The MINI
will automatically detect and select the first active input. When the selected input is turned
off, the MINI will go back into search mode until a new valid source is found.
The audio inputs are shared. If you are connecting two consoles, you may use a Y-splitter for
each audio input to accommodate both sources. Of course, you will only want to have one
console on at a time, or else the sound will mix together.
You can also connect a S-Video/composite switch to the MINI using a Y-splitter, and the MINI
will automatically work with the switch to go to your selected input.

Troubleshooting
Q: Only colorbars are shown.
A: Colorbars is the default pattern when no signal is received from the console. This indicates
an error with your console, cart or video cable. The first thing to do is to clean your cart
carefully and make sure your console is in good working condition.
Q: No image is shown.
A: Double check that the MINI is powered up and that the Digital Video cable from the MINI
is securely plugged into your TV. Try another TV and Digital Video cable. Without any console
connected, you should see a blue screen. If you do not, contact your seller for additional
assistance.
Q: Picture is noisy and/or interference is seen.
A: In almost every case, the noise originates from the console, console’s power supply and/or
the cables used to connect the console to the MINI. The noise almost never originates from
the MINI itself. In addition, to preserve image sharpness, the MINI does minimal filtering to
attempt and smooth out noisy sources. For the best image quality, always use official power
supplies for your console and shielded video cables.
For PAL/PAL-60 users, try setting the ‘COMB’ switch to ‘Auto,’ which increases noise filtering of
PAL chroma noise at the expense of slightly reduced luma sharpness.
Q: No sound is heard.
A: Double check to make sure the audio cables are connected correctly. Try another TV. The
off-spec video timing of some-retro consoles causes some displays to reject the audio stream
in the Digital Video connection. Alternatively, directly connect the audio output from your
console to your sound system and bypass the MINI..
