TORTUGA LDR3.V2 + ALIMENTATION PS12B

PREAMPLI LDR3.V2

• Preamplifier type: Passive stereo attenuator
• Inputs: Three single-ended RCA
• Outputs: Two parallel single-ended RCA outputs
• Attenuation technology: Resistive attenuation via light-dependent resistors in series/shunt (L-Pad) configuration
• Attenuation range/increments: Discrete 71 steps (70+ mute) between -60dB and 0dB
• Gain: Passive unity gain (1.0x) without buffer; no active amplification
• Output impedance: 100 ohms to 5k ohms, depending on attenuation setting
• Left/Right channel balance: 0.4dB or less
• Control system: 8-bit/16MHz software-driven digital microcontroller
• Accessories included: Apple remote, external power supply, USB cable
• Dimensions: 5.4″ x 1.75″ x 8.7″
• Weight: 3 kg

ALIMENTATION PS12B

Pushbutton/Green LED:

• On – charger connected
• Off – charger disconnected

Status LED:

• Blue – AC power connected and unit turned on
• Red (blinking) – Battery voltage low
• Red (solid) – Battery voltage too low | overrides all control inputs by connecting charger | turns off output from PS12B until battery voltage recovers

Battery Voltage Levels

• 14V – Fully Charged (max) – no load
• 12.1 -13.7V – Normal operating range under load
• <12.1V – Battery low – red LED starts blinking
• <11.9V – Battery too low – red LED solid – power supply output disconnects
