F7-USB 7-Input Compact Stereo Mixer With Effects
Seven inputs with effects and published bench figures at 29 USD — the value point of the range.
Price excludes shipping. Freight is quoted for your destination once quantity is confirmed.
Product Overview
The F7-USB is the model that does the most for the least. Seven inputs cover a small band or a presentation rig, effects are on board, and unlike most desks at this price the specification is published: 20 Hz to 25 kHz within +/-1 dB, 0 to +40 dB of microphone gain, 120 dB E.I.N., and three EQ bands at defined centre frequencies. At 29 USD with a hundred-piece minimum it is the obvious volume line for a distributor who still wants numbers on the box.
Problems It Solves
Buyers at this price are usually forced to choose between a cheap desk with no published data and a documented desk at twice the money. The F7-USB is documented at the cheap price.
Who It Is For
Distributors who need a high-volume entry model that still survives a technical question, and brand owners filling the sub-30-dollar slot in a catalogue.

Compared With Our Other Models
The F7-USB and the F4-USB share the same published bench specification; the F7-USB adds three inputs and effects for eight dollars. Step up to the CT-80S at 44 USD for an eighth input, tighter +/-0.5 dB channels and published output and headphone figures.
Use Guide
- Set gain with the channel at working level, aiming just below clipping on the loudest passage.
- Treat the three EQ bands as cuts first — 80 Hz down will clear more mud than 12 kHz up will add air.
- Apply effects to vocal channels only and leave spoken word dry.
- Use balanced connections on longer cable runs; the mic and line inputs are electronically balanced.
- Leave headroom on the main fader so the mix can be lifted without re-gaining every channel.
