CT-80S 8-Channel Audio Effects Mixer With USB
The fully specified desk in the range, with published output levels, headphone loading and mains versions for five markets.
Price excludes shipping. Freight is quoted for your destination once quantity is confirmed.
Product Overview
The CT-80S is the model to quote when the buyer asks for numbers. It is the only desk in the range with a complete published specification: mic and stereo channels held to +/-0.5 dB across 20 Hz to 25 kHz, 120 dB E.I.N. on the microphone inputs, shelving and peak/dip EQ with defined centre frequencies, and stated maximum input and output levels on every connector. Eight channels, AUX and effects sends, a tape output and a headphone stage rated into 30 to 600 ohms make it a working desk rather than a toy.
Problems It Solves
Most mixers at this price publish nothing measurable, which leaves a distributor unable to answer the first technical question a customer asks. The CT-80S ships with the figures already stated.
Who It Is For
Buyers who have to defend a specification to their own customer — distributors selling into education and broadcast, and brand owners whose datasheet has to survive comparison.
Key Benefits
Why Buyers Choose the CT-80S
Specification a buyer can check
Frequency response, gain, signal-to-noise, send levels and headphone loading are all published figures, not claims.
+/-0.5 dB on mic and stereo channels
Tighter than the +/-1 dB quoted for the F-series, which matters when the desk feeds a recording rather than a PA.
Separate AUX and effects sends
Both at +22 dBu unbalanced, so a monitor feed and an effects unit can run at the same time.
Built for five mains standards
120V 60Hz, 240V 50Hz, 230V 50Hz, 100V 50/60Hz and 220V 50/60Hz versions are documented.
Headphone stage with real loading
350 mW into 30 to 600 ohms drives studio headphones, not just earbuds.

Manufacturing and Quality
How This Desk Is Built and Checked
The CT-80S is assembled in Enping using surface-mount technology, in the same plant that builds our wireless systems. The factory's instrumentation includes Motorola high-frequency wireless testing instruments, an HP high-frequency signal source, Fourier analysers and frequency sweep instruments.
Factory audit is acceptable for buyers who need to verify the process in person.
TBC Certification marks such as CE and RoHS are not published on the factory catalogue for this model. Confirm the certification you need on your enquiry before ordering.
Customisation Options
- Own-brand silkscreen and logo
- Retail and export packaging to your artwork
- Mains version selected per destination market
- Documentation and manual in your language
Compared With Our Other Models
The CT-80S is the specification benchmark of the range. The F7-USB gives seven inputs at a looser +/-1 dB for 29 USD; the RX12 adds four more channels and Bluetooth but publishes no bench figures. If the decision is being made on a datasheet, this is the model.
Use Guide
- Confirm the mains version matches the destination country before shipping — five versions are built.
- Start with all EQ controls centred; the mid is peak/dip at 2500 Hz and cuts as usefully as it boosts.
- Keep maximum input inside +24 dB on mic and TRS inputs and +20 dB on other line inputs.
- Use the tape output rather than the main output when feeding a recorder, so the recording is unaffected by the main fader.
- Match headphones between 30 and 600 ohms to get the rated 350 mW.
