User manual FOSTEX X-26

[. . . ] Heed warnings - All warnings on the appliance and in the operating instructions should be adhered to. Follow instructions - All operating and use instructions should be followed. Water and Moisture - The appliance should not be used near water - for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, and the like. Carts and Stands - The appliance should be used only with a cart or stand that is recommended by the manufacturer. [. . . ] Then, slowly move the head demagnetizer tip to the head and wave the tip up and down several times close to the head surface. 3) On completing the above procedures, slowly draw the demagnetizer away from the head and switch it off when it is more than one meter away from the head. As demagnetizm in the head cannot be seen, unlike the soiled head, routine demagnetizing is necessary. It is recommended to do so at the same time the head is cleaned. 3-2. Test Equipment and Adjusting Tools The following tools and equipment are required for adjusting the Model X-26. 2) Connect an AC volt meter to the TAPE OUT and playback the 12. 5 kHz section on the TC-284W test tape. 3) Rotate the REC/PLAY head azimuth adjusting screw to obtain a maximum output level. 3-7. Tape Speed Check and Adjustment 1) Confirm that the Pitch control knob is at center position. 2) Connect a frequency counter or wow & flutter meter with frequency counter to the TAPE OUT and playback the Model 9152 test tape. 3) Check the tape speed and wow & flutter if they satisfy the following specifications. Tape Speed: 3000 Hz ± 30 Hz at both BOT (beginning of tape) and EOT (end of tape) positions Wow & Flutter: 0. 25 % (CCIR WTD) at both BOT and EOT positions 4) If the tape speed is not within the above specification, adjust R43 (3. 3 k) on the R/P AMP PCB assy. (The switch should be turned on. ) 2) Apply a 400 Hz, -35 dBV (18 mV) signal to the INPUT 1 and 2 phone jacks. 3) Record the signal, rewind and playback the recorded section of the tape and memorize the output level at TAPE OUT 1 ~ 4. 4) Next, apply 6 kHz & 12 kHz, -35 dBV (18 mV) signals to the INPUT 1 and 2 phone jacks. 5) Record the signal, rewind and playback the recorded section of the tape. 6) Check if the 6 kHz / 12 kHz output level at TAPE OUT 1 ~ 4 is within ± 2 dB comparing to the 400 Hz output level. If the AC volt meter reading is not within the above specification, adjust the pot R133 ~ 433 (220 k) on the R/P AMP PCB assy so that the recording level at 6 kHz will be within the specification. 3-14. Measurement 1) Connect a distortion meter, 400 Hz HPF and 30 kHz LPF to TAPE OUT 1 ~ 4 and set the controls under the same condition as 3-12. 3) Playback the recorded part and check if the distortion level is less than 2 %. 3-15. Erasure Measurement 1) Connect a 1 kHz bandpass filter and AC volt meter to TAPE OUT 1 ~ 4 and set the controls under the same condition as 3-12. 2) Record a 1 kHz, 0 dBV (1 V) sine wave signal which is 10 dB higher than the reference recording level on a blank tape. 3) Rewind the tape to the start point of recording and advance it by a short length.
