Presentation
The Taramps X PRO 234 crossover is designed for fine-tuning audio details with frequency filtering, bass/mid/treble equalization, and volume control, delivering peak performance. It features a built-in player with multiple connection options: Bluetooth, USB, memory card, and front auxiliary (P2) input, enabling playback from various sources. An optical input is also included, ideal for connecting to TVs.
With a 1U rack height (44.45 mm), the X PRO 234 is auto-voltage (90V-240V) and uses a switching power supply for higher energy efficiency. The unit is turned on/off via the front panel switch. For prolonged periods of non-use, unplugging the unit is recommended. The product uses a plug according to the Brazilian NBR 14136 standard; a compatible adapter may be needed for other regions.

Bluetooth
To use Bluetooth, select the "bt" mode. The X PRO 234 enters pairing mode. Search for "TARAMPS" on your smartphone, tablet, or computer and complete the pairing process. To pair a new device, first disconnect the currently connected one.
Bluetooth specification: Class II, with a maximum range of up to 50 meters (164 feet). Actual range may vary based on environment and connected device.
Pairing Example (Visual Description):
On Android: Navigate to Bluetooth settings, ensure it's on, and search for devices. "TARAMPS" should appear under available devices. Tap to connect.
On iOS: Navigate to Settings > Bluetooth. Ensure Bluetooth is on. Your iPhone is visible to nearby devices while Bluetooth settings are open. "TARAMPS" should appear under "Other Devices" or "Paired Devices" once connected.
Connection Examples
Stereo Connection Example:
This setup connects an Audio Mixer (e.g., T 0804 PLAYER FX) to the X PRO 234 Crossover, then to an Amplifier (e.g., T 2.800) and Speakers (e.g., T 400.4 HF).
Signal Path: Audio Mixer Output -> X PRO 234 Inputs (A & B) -> X PRO 234 Outputs (CH1/CH2, CH3/CH4) -> Amplifier Inputs -> Amplifier Outputs -> Speakers.
Configuration Notes:
- For the X PRO 234: Set HPF to 120 Hz, and the MONO/STEREO selector to STEREO.
- For the Amplifier (T 2.800): Set Channels A and B to FULL, and the MONO/STEREO selector to STEREO.
Mono Connection Example:
This setup connects an Audio Mixer (e.g., T 0804 PLAYER FX) to the X PRO 234 Crossover, then to an Amplifier (e.g., T 2.800) and Speakers (e.g., T 1200.1 LF + T 400.4HF).
Signal Path: Audio Mixer Output -> X PRO 234 Inputs (A & B) -> X PRO 234 Outputs (CH1/CH2, CH3/CH4) -> Amplifier Inputs -> Amplifier Outputs -> Speakers.
Configuration Notes:
- For the X PRO 234: Set HPF to 120 Hz, LPF to 120 Hz, SUBSONIC to 40 Hz, and the MONO/STEREO selector to MONO.
- For the Amplifier (T 2.800): Set Channel B to FULL, and Channel A to FULL. The MONO/STEREO selector should be set to STEREO (as it's receiving a mixed mono signal from the crossover's B input, which is then duplicated to A for the amplifier's stereo inputs).
