Now supplied with version 2 firmware CTP presents the second incarnation of their essential equipment for the sound and audio installation engineer. The dBbox2 allows monitoring, metering and generation of analog, AES/EBU and SPDIF audio from a pocket sized box.
The dBbox2 includes a simple five key menu interface to make any test as simple as possible.
The case has been formed using our own purpose designed aluminum extrusion then machined and painted to give the unit it’s very individual look.
What you can do with the dBbox2:
- Monitor mono or stereo line level analog inputs using the built in speaker or 1/4 inch or 3.5mm headphones. Meter using either PPM or VU scale also with stereo phase meter.
- Monitor microphone level analog inputs, with or without 48v phantom power, using the built in speaker or headphones. Meter using either PPM or VU meter scale with stereo phase meter.
- Monitor AES/EBU balanced or unbalanced inputs using the built in speaker or headphones. Meter using -18dBFS, -20dBFS, PPM or VU scale with stereo phase meter.
- Analyze AES sample rate, status and data errors.
- Generate steady tone, tone sweep, GLITS, EBU, left only, right only, on both analog and AES/EBU outputs. Tone frequency may be adjusted in third octave steps. Adjust Tone level from +10 to -60dBu in 1dB steps.
- Use the built in microphone to talk to analogue or AES/EBU outputs.
- Generate pink noise and send to left/right/both outputs in both analog and AES/EBU with a choice of levels in 1dB steps from +10dBu to -60dBu.
- Use the built in microphone to talk to AES outputs with a choice of levels and with a built in limiter.
- Send an external mic to analog and AES outputs with gain adjust and phantom power.
- Phantom power test with voltage read out. Also useful for checking 2 wire talkback power and channel.
- MIDI receiver identifying channel, note on/off and note number.
- MIDI transmitter with a choice of note, channel and velocity, note on and note off.
- Analyse incoming MIDI signals with pass through.
- Use the dBbox2 as an analog to digital or a digital to analogue converter with adjustable gain in 1dB steps, a limiter and HF, LF and Mid range equalization.
- Mono or stereo microphone amplifier with 48v phantom power and analog, AES/EBU or SPDIF output. Also with adjustable gain in 1dB steps, a limiter and HF, LF and Mid range equalization.
- Four wire box using the built in microphone and speaker or headphones.
- Monitor and meter 2 wire channels.
- Test XLR, BNC and MIDI cables.
- Output tone and monitor incoming audio simultaneously using Analog or AES inputs and outputs. Particularly useful for frequency response and performance tests.
- Intelligent power control to extend battery life. The dBbox2 automatically switches off all electronics not required for the current task. A dynamic battery level indicator shows if you have enough battery power for a selected function.
- Switchable back light.
- Update firmware online using the dBbox2 USB port via CTP Systems web site.
- External power input via a standard mini USB.
- Protective case available with belt mount.
- The architecture of the dBbox2 is based around a powerful digital signal processor and a separate micro controller allowing us to add many more features in the future with just a firmware download from our website.
- For the future we are also working on software to allow the dBbox2 to be used as a ‘test hub’ allowing it to be controlled by both PC and Mac software with test sequences and results available on the computer screen.
- The SPDIF functions are available on the input and output BNC connectors. We can supply compact adapters to convert to phonos if required.
- The dBbox2 takes a PP3 size battery, alkaline battery highly recommended. Battery life is around 8 hours continuous but very much depends on the function selected. With phantom power selected, a fair bit less!
- We also offer a soft case for the unit and a universal mains adapter.
- Dimensions: 146mm tall, 89mm wide, 48mm deep.
