Description
AUDIONICS SOUNDCHECK SC1 MONITORING UNIT
The compact Soundcheck system monitors analogue audio signals by means of a pair of powered speakers and a PPM meter. One of six stereo inputs may be selected for checking in control rooms, equipment racks, dubbing rooms or similar facilities, and the unit may also be used as a simple source-selection facility. The unit is AC powered and occupies only 2U of rack space.
An electronically interlocked relay source selector is combined with a pair of electronically equalised, powered speakers and a stereo analogue PPM meter. The rear panel is fitted with a 56-way Edac connector to input the 6 stereo balanced signals. Front panel facilities include a stereo pair of test jack inputs (B gauge, wired as break jacks) which inject signals into the system after the relay matrix directly into the electronically balanced inputs to the monitoring chain. (Output feeds of this signal, prior to the volume control, are provided on the Edac connector). The volume control adjusts the level to the speakers, or to the stereo headphone socket (A gauge), which mutes the speakers when in use. The speaker equalisation produces an extended output range, suitable for “confidence” checking and fault finding. The PPM meter is a dual, 24-segment LED type marked -12 to +12 in 4dB steps with 1dB resolution. A single bi-colour LED shows the phase relationship between the left and right inputs. The transformer option includes the cost of two factory-fitted high quality bridging transformers. The BBC option substitutes a B-gauge headphone jack wired with capsules out of phase, in accordance with BBC convention. Power supply: 230V AC via an IEC mains inlet with fuseholder (cable not supplied). Dimensions: 2U rack-mounting, 300mm deep.
