Heady master – Merrill's new Master Tape Head preamplifier [$15'000] is for reel-to-reel decks and upgrades the previous unit with new VU meters for calibration, HF level adjustments, output level control, channel balance, VU meter level adjustment and a new "studio-quality tape head gain circuit. It's an ideal addition to the Ampex ATR 100, 102 and 104 models or Otari MTR desks. We can provide the plug-in card to access the tape head directly on the Ampex ATR 100 series machines, replacing their on-board preamp cards for an order increase in performance. We set our max gain to 71dB. There are six speed and equalization settings for 3.75ips/NAB, 7.5 IPS/NAB, 7.5 IPS/IEC, 15IPS/NAB, 15IPS/IEC and 30IPS/AES. These are accessed from the capacitive 5" color touch screen. Your configuration is saved to memory and restored upon power up. The machine accepts tape outputs from 0.3mV-6mV and has a maximum peak-to-peak output range of 24 volts. The Kratos II external power supply gives this an ultra-low noise floor with great immediacy."
