- Dividing network with a crossover frequency of 1.2 kHz ideal for 2-way horn systems. In addition to an attenuator for high frequency adjustment, it is also equipped with an HF boost switch, so it is possible to adjust the sound to the optimal sound when using a bi-radial horn when using PA. The exterior has dullness and small scratches. (YONEJIMA Satoshi) Maintenance information: 2020.11.8 Maintenance completed (the lug plate is broken at the attachment part of the internal wiring, repaired with bare terminals (carried out on both left and right). Reinforce the coil with silicone so that the attachment does not slip. Terminal rust removal, acid washing treatment, polishing, cleaning, insulation bush & mounting screw replacement ATT (SW type) contact cleaning. Frequency characteristic measurement checks (~ approx. 42 kHz) were performed, and the results were good, so the original capacitor was continuously used. (Input/output waveform and balance check, sound output check) Accessories: no accessories Main Specifications: Crossover 1200 Hz impedance low range 8 ohm/high range 16 ohm high frequency attenuation 6/8/10 dB switch
