BEACHTEK BALANCED INTERFACES - Camcorder and Camera Audio Adapters - XLR
These interfaces convert between professional balanced XLR connectors and the domestic audio inputs on camcorders and digital SLR cameras. The range includes passive and active units, some with phantom powering or metering. Includes hardware to secure the interface to the base of the camcorder. Two year, limited, manufacturer's warranties are included with all adapters.
DXA-2T - Universal camcorder, passive, robust
A passive device for small compact camcorders. A threaded screw and retractable azimuth pin connects the box to the camcorder, and a tripod bush is provided in the base. Two XLR inputs are transformer balanced. An auxiliary input is provided as an unbalanced 3.5mm jack socket, which injects signals, such as radio microphones into the right channel. The output is unbalanced, at microphone level; a 3.5mm stereo jack socket and supplied output cable, terminates in a right-angled, 3.5mm stereo jack plug. Each channel has a switch to select microphone or line level, and a mono/stereo switch allows the connection of a mono input to both channels. A ground lift switch assists in removing annoying hum components.
Inputs: Microphone -35dBu nominal, -6dBu maximum (ideal), for low impedance microphones. Line: -10dBu nominal, +4dBu maximum (ideal), high impedance. Response: 20Hz to 20kHz +/-3dB. Chassis: Die-cast aluminium, with shaped plastic bezel offering protection of controls and switches. Dimensions: 95 x 64 x 38 (l x w x h)mm. Weight: 280g.
Included accessories: 3.5mm stereo to 3.5mm stereo output cable.
DXA-SLR ULTRA - Universal DSLR camera, active, peak LCD meters, playback monitoring, phantom power
For use with any DSLR camera that has a microphone mini-jack input, this variant is similar to the DXA-2T, and has most of the same features except it uses active circuitry to allow more sensitive recording. XLR inputs are combined with 6.35mm jack inputs, allowing connection from a variety of input sources. Each channel has a switch to select line or microphone level (with or without phantom power). In addition a pair of 8-stage VU meters on an LCD back-lit display are added for monitoring output levels. These are calibrated to indicate levels between -18dB and +3dB, and are useful to ensure optimum levels are sent to the camcorder inputs. Also a headphone amplifier with volume control is added, for monitoring camera input level, as the camera may not feature this function, or the playback from the camera via a 3.5mm 3-pole minijack socket. A pair of red, LEDs indicate when a switchable, fast-acting limiter is activated by high levels, which can help to avoid signal overload. Other features are switchable 12V or 48V phantom power, high/low channel gain switches, and a power/low-battery indicator LED. There is no ground-lift facility, unlike the DXA-2T.
Additionally, a supplied base plate can be fitted to provide support rods on which to attach a matte box, follow-focus or other such device. Two 75mm rods are provided, but can be extended via the purchase of additional rods. The base plate can then be attached as usual to the camera.
Power source: PP3 9V alkaline or lithium battery (typically lasts 3 hours (alkaline), 8 hours (lithium).
Inputs: Microphone (Hi gain) -20dBu, (Lo gain) +10dBu; Line: +14dBu. Gain: 'Lo' gain 0dB, 'Hi' gain 30dB. Response: 20Hz to 20kHz +/-0.5dB. THD: <0.01% @ 1kHz, -30dBu. Signal to Noise: 85dB @ 1kHz, -30dBu. Battery: 9V PP3 type, 3 hour typ. with alkaline, 8 hour typ. with lithium (no phantom). Chassis: Die-cast aluminium, with shaped plastic bezel offering protection of controls and switches. Dimensions: 152 x 95 x 44 (l x w x h)mm. Weight: 510g (adapter), 230g (rod mount).
Included accessories: 3.5mm stereo to 3.5mm stereo output cable, 3.5mm stereo to dual RCA phono AV output cable for camera playback monitoring.
