Quadratt 1U
Four channel active/buffered attenuverter and summing mixer. Each channel has a knob functioning as a unipolar attenuator or bipolar attenuverter, with inputs normalled to +5V DC and outputs normalled into the adjacent channel for submixing.711
Capabilities 4
- Attenuatorattenuator
- Four independent attenuator channels, each switchable between unipolar (0 to +5V out with normalled input) and bipolar (-5V to +5V out) modes.711
- Attenuverterattenuverter
- 711
- DC Voltage Sourcedc-offset-source
- Each input is normalled to a precision +5V DC source, enabling manual offset voltage generation when nothing is patched in.711
- Mixermixer
- Outputs are normalled from left to right, allowing submixes of 2, 3, or all 4 channels. OUT D outputs the sum of all four channels when A-C are unpatched.711
Jacks 8 — 4 in / 4 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (4) | |||
| IN A | mixed | — | Input for channel A. Normalled to +5V DC when nothing is plugged in.711 |
| IN B | mixed | — | Input for channel B. Normalled to +5V DC when nothing is plugged in.711 |
| IN C | mixed | — | Input for channel C. Normalled to +5V DC when nothing is plugged in.711 |
| IN D | mixed | — | Input for channel D. Normalled to +5V DC when nothing is plugged in.711 |
| Outputs (4) | |||
| OUT A | mixed | — | Output for channel A; the attenuated/attenuverterd value of IN A.711 |
| OUT B | mixed | — | Output for channel B; attenuated/attenuverterd value of IN B. When OUT A is unpatched, outputs the sum of channels A and B.711 |
| OUT C | mixed | — | Output for channel C; attenuated/attenuverterd value of IN C. When OUT A and OUT B are unpatched, outputs sum of channels A, B, and C.711 |
| OUT D | mixed | — | Output for channel D; attenuated/attenuverterd value of IN D. When OUT A, B, and C are all unpatched, outputs sum of all four channels.711 |
Parameters 8
| Name | Type | Range | Behavior |
|---|---|---|---|
| Channel A Attenuator | knob | 0V – 5V | Attenuates the voltage level at IN A. Behavior depends on the position of the polarity switch. Attenuation amount is linear.711 |
| Channel A Polarity Switch | switch | — | UNI: channel is a standard attenuator (0 to full input voltage). -/+: channel is a bipolar attenuverter (-full to +full input voltage). Input is normalled to +5V when nothing is patched.711 |
| Channel B Attenuator | knob | — | Behaves the same as the Channel A attenuator but for channel B.711 |
| Channel B Polarity Switch | switch | — | Behaves the same as the Channel A polarity switch but for channel B.711 |
| Channel C Attenuator | knob | — | Behaves the same as the Channel A attenuator but for channel C.711 |
| Channel C Polarity Switch | switch | — | Behaves the same as the Channel A polarity switch but for channel C.711 |
| Channel D Attenuator | knob | — | Behaves the same as the Channel A attenuator but for channel D.711 |
| Channel D Polarity Switch | switch | — | Behaves the same as the Channel A polarity switch but for channel D.711 |
