2.7 Speed Conversion (BIII)
Normally, the MX-5050BIII-2 is shipped from the factory with set at High Speed (15/7.5 ips).
If you want to change this to Low Speed (7.5/3.75 ips), follow the steps below.
1. Remove the bottom panel to access the CONTROL PCB. Rotate the
CONTROL PCB.
2. The Speed Version Select SW1-1 is located on the CONTROL PCB. Change
the switch position to the LOW position. (☞§2.3.)
3. Replace the bottom panel on the machine.
4. Make all necessary adjustments (Reproduce EQ, SRL, Bias Record EQ,
Record Level) referring to the corresponding explanation in Section 7.
NOTE: The MX-5050MKIV-2 cannot be changed to Low Speed.
2.8 Equalization Change
The Equalization type is set to the customer’s specifications at the factory. The setting can
be changed between NAB and IEC by sliding the EQUALIZER switch on the rear panel (☞
§2.3). If the setting is changed, equalizer adjustments (§§7.3.3 and 7.4.5) must be made.
