WORKSHOP 2&lt;br /&gt;
----------&lt;br /&gt;
I    b)   12 sine/square wave generators (Jason) associated with keying unit&lt;br /&gt;
             and adjustable decay unit (workshop construction)&lt;br /&gt;
          High stability decade sine wave generator (Muirhead-Wigan)&lt;br /&gt;
          Sine wave generator with frequency modulation (Br&amp;amp;uuml;el and Kjaer)&lt;br /&gt;
          Square wave shaper (Muirhead)&lt;br /&gt;
          Zither and guitar with electromagnetic pick-ups&lt;br /&gt;
&lt;br /&gt;
II   a)   Reverberation plate (EMT) with remote control&lt;br /&gt;
          4 high/low pass filters with 9 cut-off frequencies (BBC)&lt;br /&gt;
          Variable frequency response control unit (BBC)&lt;br /&gt;
&lt;br /&gt;
III  a)   Tape recorder, 7&amp;amp;frac12; and 15 i.p.s.  (EMI, BTR 2)&lt;br /&gt;
          3 tape recorders, 7&amp;amp;frac12; and 15 i.p.s.  (Philips, EL3503)&lt;br /&gt;
          Tape recorder, 7&amp;amp;frac12; and 15 i.p.s.  (Ferrograph)&lt;br /&gt;
          Disk playing equipment (BBC)&lt;br /&gt;
&lt;br /&gt;
     b)   8-track tape recorder with continuously variable speed from&lt;br /&gt;
            0 to 40 i.p.s.; uses 1&amp;quot; tape (Leevers Rich)&lt;br /&gt;
          Specially designed mixing controls with 20 channels each with a&lt;br /&gt;
            pre-set attenuator.  8 channels are normally associated with&lt;br /&gt;
            8-track tape recorder.  The remaining 12 are low level input&lt;br /&gt;
            channels, with switching facilities making available three&lt;br /&gt;
            types of artificial reverberation.  Each channel may be&lt;br /&gt;
            independent, or switched to either of two group faders&lt;br /&gt;
            associated with different filters.  Remote control of four tape&lt;br /&gt;
            recorders and acoustic fold-back facilities are included.&lt;br /&gt;
&lt;br /&gt;
IV        Oscilloscope (Cossor, double beam)&lt;br /&gt;
          Peak programme meters (BBC)&lt;br /&gt;
&lt;br /&gt;
V         Loudspeakers (BBC)&lt;br /&gt;
&amp;lt;/PRE&amp;gt;&lt;br /&gt;
