The Gigagain TISO-7 is a compact multi-output power supply for guitar and bass pedals. Its 7 fully isolated DC outputs provide each pedal with a separate power channel, helping to reduce noise, hum and unwanted crosstalk between pedals.

The power supply is suitable for pedalboards combining analogue pedals, digital effects, delays, reverbs, multi-effects and high-current pedals. Each channel can deliver up to 6 W, with up to 660 mA available at 9 V.

Flexible, isolated outputs

All 7 outputs can be manually set to 9 V, 12 V, 15 V or 18 V:

• 9 V: up to 660 mA per output
• 12 V: up to 500 mA per output
• 15 V: up to 400 mA per output
• 18 V: up to 330 mA per output

Always check the pedal’s manual or markings before changing the voltage. A pedal that only supports 9 V must not be connected to an output set to 12 V, 15 V or 18 V, as this may damage its electronics. Pedals that support higher voltages may, in some cases, provide more headroom and dynamics when operated at 12 V, 15 V or 18 V.

Outputs 1 and 4 support polarity switching. The anti-mistouch design is intended to help prevent accidental changes, but the polarity should always be checked before connecting a pedal, as incorrect polarity can damage certain pedals.

Power meter and channel monitoring

The built-in power meter with status LED shows the total load:

• Green LED: the power supply is operating within a safe range
• Yellow LED: moderate load
• Red LED: the total load is approaching the maximum

The outputs also feature individual monitoring with current-limit indicators. If a channel exceeds its limit, an indicator identifies the output causing the problem.

24 V AUX output

A 24 V DC AUX output with up to 2 A can be used as a daisy-chain output for compatible equipment requiring 24 V DC. The total maximum capacity is 48 W. The TISO-7 includes a 24 V 2 A power adapter and supports an AC input range of 90–265 V at 47–63 Hz.

Construction and specifications

The red metal housing has a low profile and is designed for placement under or on a pedalboard. Dimensions are 124.5 x 90.2 x 22.6 mm, and the weight is approximately 0.36 kg.
