Description
The DIRECT4 combines features found on four DIRECTOR ® direct boxes in one unit. Perfect for converting unbalanced signals from multiple instruments, keys, acoustic guitar preamps, CD and tape players, computer sound cards, etc. The input and output grounds of each section are isolated from each other. This allows the DIRECT4 to be used as if it were four completely separate DIs without fear of creating ground loop interaction.
Features:
- 1/4 parallel wired in/out jacks
- Ground Lift switch to help eliminate hum and buzz
- Filter switch to help reduce amplifier noise and hiss
- -20dB pad switch for connection to hot input signals
- Uses Whirlwind's TRHL-M transformer with metal shield
| Impedance Ratio (input to output) | 133:1 |
| Frequency Response | 20Hz-20kHz ±1dB |
| Level Change (input to output) | -20dB (pad out), -40dB (pad in) |
