NOTES

1. For low voltage operation between JU and 13V, lUkQ resistors are requlnbetween each output and earth to prevent cUpping; this will reduce the gain tapproximately 6d13. Similarly between 8 and IOV, 3. 3kQ resistors. are requirecwith a reduction in gain to apprOXimately 3dB.

2. Each output 1s at a d. c. potential of approximately 6Vwhlch should be decoupllbefore being fed into the succeeding audio stage.

3. The module is a ligned for optimum performance when used with an i. f. amplifiewith the a ttenuation of O. 5dB at 38kHz (relative to 1kHz). For test purposes, t~

(a) The mod}lle may be soldered directly into a circuit using either a Boldering ironor a Bolder bath _ The soldering temperature must not exceed 245°C and thesoldering time mUl:>t be less than 5 seconds-_

(b) If it is desired to bend the terminations, extreme care must be taken to preventdamage to the printed circuit of the module.

(c) All soldering irons and input signal supplies should be earthed to prevent break­down of the transistors.
